[@chadwik4000]

@brassfacts could you possibly do a video and speak to the popularity of the 18-inch barrel. I've looked over a lot of numbers in regards to Velocity and 18 inches seems to be a pretty lame jumping velocity from 16 in yet 18 to 20 in yields a big jump similar to 14 1/2 to 16. I'm off the frame of mine now that I'll either run 16 420. 18 inches only yields a nominal increase in velocity from 16, yet two more inches from 18 to 20 and there's another big jump. Thoughts?

9 Holes has a fantastic podcast episode about the Mk12 SPR and its obsolescence in the modern AR15 market. The quality in a 1-10x optic and accuracy in modern machined barrels and free float rails kind of makes most GPRs also fit the criteria for what the SPR was meant for in its time of conception. So really i think the focus nowadays should be on dudes understanding and being confident at shooting at ranges past 500yds with whatever "GPR" they have.

[@compulsivegunbuyer]

Exactly right. The most important training element for the modern minute man is increasing your personal effective range with whatever platforms you own. Too many folks have 600-1000 yard guns and have never shot past 200.

@jurpo6 I'd be happy if the average minute man could shoot past 200, but there is absolutely a case for longer range training. The original Minute Men relied on sniping to harass the British on the road to Concord....so I'm not sure I see your point.

It's worth remembering that while the mk12 was 18", the spr builds it was based on were 16". The army wanted a longer barrel, and it fell out of favor after that happened.

[@BrassFacts]

good point! Vindicated or something

[@LRRPFco52]

The original light Sniper carbines were free-floated 723s with Ops Inc suppressors, and had mounts for PAQ-4C or AIM-1 LAMs, plus optics, 2-stage triggers, and select CMV barrels that shot well. They started out as lightweight 14.5" carbines with CLGS, FSB pocket cuts, and rail sections bolted on where needed. Some were aluminum tubes, while others were fiberglass from KAC SR-25s or ArmaLite AR-10s later on (1996). The original Sniper carbines were put together after Panama due to Combat Development folks collecting AAR comments from everyone that was part of Just Cause. Most of them had the "CAR-15" cheek piece and John Masen sharktooth rubber recoil pad zip-tied to the Colt Fiberlite stocks. Lone Star Ordnance grips were very common for both the main PG and the VFG. They had Harris 6-9 bipods that would be attached in the dismounted local overwatch support role. When doing aerial sniper overwatch/support, they used Aimpoints.

[@LRRPFco52]

Magnified optics were Japanese Microdots and even some early ACOGs once Dam Neck guys asked their armorers to duplicate what they saw in Army JSOC. M4A1 hit JSOC in 1994, so there were a lot of Sniper carbines that transitioned with the front-end, but mounted up in an M4 upper. Prior to M4 production, there were several 723s that had shaved carry handles and Weaver rails drilled and tapped onto the uppers, then risers with normal scope rings attached. Some had 16" barrels. Dam Neck snipers had Lilja make them stainless 17" CLGS barrels and did reflex cans over those, both with and without FSB pocket cuts on their 727s. Assaulters even got carbine-length free float tubes on their 727s and M4A1s before/as the RIS was being developed in response to all this at KAC. There's a great photo of Sawman Sawyer with a non-FSB pocket cut Sniper carbine with reflex can, PEQ-2A, Harris, I think a Leupold LPVO, with a SIMRAD mount on it. This is all way before the Mk.12 prototypes even existed. Range 37 SOTIC Committee guys and White-side SEALs saw the JSOC Sniper carbines and wanted something similar. That's when enough momentum built up and Crane was brought on board to do the SPR uppers, and complete rifles with A1 lowers. Army JSOC got KAC MREs to replace the older FSB pocket float tubes, since they are much easier to remove and install for their frequent barrel-changes on The Unit shoot schedule. It's also why The Unit didn't stick with stainless pipes, because they shot out too quickly. CMV lasted longer of course, so they went with accurate CMV barrels instead. They had some issues with the 3-piece collar Ops Inc cans with return-to-zero, so KAC made the NT4 in response. Allen Engineering developed the brake and conucal alignment collar with specific barrel dims to address that as well, which is what the SPR got. Dam Neck had some slick transitional Sniper carbines that had the KAC rifle free-float RAS, with 16-17" barrels and reflex cans. Big difference with the Mk.12s was 18" Douglas pipes with RLGS (smoother impulse), and the PRI flip-up front sight/gas block, as well as the new collar. The challenge is getting back to the lightweight, shorter 14.5" 723 carbine, with Mk.12 recoil/sight picture and friendliness to clip-on NVDs. 723s and 727s with FSB pocket float tubes weren't friendly to in-line clip-ons.

[@LRRPFco52]

So the barrel history in JSOC Sniper carbines goes like this: 14.5" pencil with Reflex can 14.5" 727 profile with heavy forend and 203 step cut, reflex can 16" CLGS with Reflex and early KAC NT4 17" CLGS Lilja with Reflex can Whatever SOCOM did after that with the prototype SPR uppers came later, settling on 18" for Mod 0 and Mod 1, 16" for Mod H. Original match ammo was loaded by Hornady and Black Hills in the 68-69gr weight classes. AMU, Black Hills, and Crane worked on 77gr Nosler and SMK later on, which of course became Mk.262 OTM. There's a lot of history behind the scenes that never saw the light of day, due to how clamped-down JSOC is with their CDD stuff.

[@bradsimpson8724]

Kyle Defoor spoke about this. Around the same time NSWC Crane wanted to standardize the "recce rifles" of the time, the 5th Special Forces Group wanted an accurized 20" upper receiver. Both the Army Marksmanship Unit and the Marine Corps wanted the same 20" barrel. When NSWC Crane specced the initial upper receiver, it had a 20" barrel. But the procurement systems of the time wouldn't approve it, because there were already 20" barrels in the system. Because they were accountants and not warfighters, they didn't see the value in a differently-specced barrel of the same length. Crane got around this by simply changing the specification to 18". The Mod H came to be because unlike the Marines, the AMU, and the 5th SFG, the SEALs didn't want a dedicated semi-auto sniper; they wanted a general-purpose rifle with some added capability, and the longer barrel pushed too far in the other direction for a lot of them. Ultimately, the 18" barrel on the most well-known SPR versions was actually not wanted by either side, but rather due to a quirk in the procurement process. Sorry to necro your long-past post, but it's an interesting tidbit.

[@tomitiustritus6672]

The core problem with this prepper/shtf-fantasy is: When shtf, which is historically precedented and abundant, the communities and populations that get to live to see the end of it are those that carry on and stick together. Most of prepper and shtf-fantasy culture is based around the assumption that "everybody is on his own". This does not only lead to a dead end for the prepper, it also contributes actively to fracturing the community and to the community, prepper included, to go under. In most shtf-scenarios, except one that is actively brought about by tribalist or sectarian warfare in the first place, people in general don't react by immediately going Mad Max and murdering each other for a sack of potatoes. People help each other and try to get to the other end of it together. In the exception mentioned above, lone wolfing will also get you mostly killed.

"we against the world" is inacceptable

[@PaddyInf]

5:28 I'd suggest that a .308 AR can be pulled into the role too. In the British Army, each 8-man section has a sharpshooter with a 16" 7.62 LMT. We train to use this weapon for CQB as well as longer ranges. Essentially, the sharpshooter runs through the same drills as the other riflemen and can function in the same role, but with an added reach. This has worked well for us.

[@480JD]

The crazy thing about urban vs rural areas, is that there's the potential for longer shots in a city environment due to the cleared foliage, taller lookout spots, and long wide open lanes such as roads and highways that give you long distance visibility as opposed to biomes like forests and even deserts where there is an abundance of cover and concealment. And where you'd be able to pass by a possibly hostile patrol party by mere dozens of yards without either knowing the other is there depending on the circumstances.

[@johnw4999]

11:35 I did the same thing, took my 16-in Geissele SD and built it in to a similar role, a convertible if you will. Topped with a S&B 1-8 Dual CC, Atlas bipod, Surefire SOCOM, BH Mk-262 Mod 1 C, it’s a .5 MOA to my range’s limited distance of 400yds. I say convertible because I can quickly remove the bipod and silencer to make it more CQB friendly, though I have SD builds of similar set up in 11.5 and 14.5 p/w running a Mini-2 silencer, EoTech w a 5x magnifier. All superbly accurate, but the 16-in gives me a good bit more velocity out the gate. All are set up to accept NV should the need arise.

[@Minutes-Mils]

Glad youre covering this concept, i had the same idea a couple years back, 13.7 AR with a suppressor, 1-6x, WML, and a bipod, primarily using 75-77gr ammo. Its more of a GPR/SPR hybrid. Had 1-8x for a bit, but decided to lighten the rifle with a lighter optic and a lighter rail before pinning. Now i have an 8.7lb rifle that is is the same length as a 20 inch, capable out to 600yd first round hits no problem. Good video.

I run a 13.7 with a similar setup, only I went with a 3.5-18 optic and piggybacking a red dot. It's a night and day build. She's about 14lbs right now, so I lighten up everywhere else to make up for it

[@kalanipitmon7817]

14.5 is the perfect do all length imo. I run a ddm4a1 with an exps3-0 on it now, but used to use a 1x6 and shooting 300yards was as easy as shooting 25yds. Also an easy length to manuever inside a house or room with while still getting decent fps. A 13.7/9 wouldnt be bad to go with either . But i do love my 18inch as well for them zoomers

I've been thinking about taking this exact set up and build but chambering it in 308. Not a battle rifle set up but an SPR/DMR for suburban areas where increased penetration is required because of structures but also the need for a "longer" ranged cartridge that can more easily buck the wind. The wind issue is something that doesn't get covered because of how of a non issue it is to many. However man made wind breaks & wind alleys IE streets heavily lined with buildings (city blocks, row houses, tight neighborhoods) that channel wind and intersections where turbulent wind collides the slower surrounding air. This can be much more violent than in a field or flat land where most people shoot.

[@DinoNucci]

Wrong

[@BandAid350z]

Do some research on 308 bbls being shorter than 16”. They tend to suffer more velocity drop and also more wasted powders means louder and brighter signature at the muzzle. Also, good luck on building an AR10. I speak from experience they’re kinda finicky. You might have better luck buying off-the-shelf.

Galil ace in .308 isn’t far off from this, I would still go with the 16” barrel myself however. Mine is surprisingly accurate but does suffer huge accuracy loss after it’s hot. First round hits at 700 yards has been no problem what so ever though.

Running a 20" HBAR 5.56 chamber 1-8 twist with a 4-14x44 and a top dot over a KE Arms KP15 lower as my SPR. My GPR is a 16" 5.56 pencil barrel in 1-8 with a 1-8x and a top dot. It's set up exactly the same as my 10.5 build. Same scope, same light, same positioning of the pressure pad, same LAM, everything. I highly recommend something in the 4-14x range with a top dot if you're running an SPR. Especially if you're running an 18"+ barrel. Id even consider the Primary Arms SLX 4-16x44 with HUD DMR reticle or R Grid 2b reticle to be a good SPR scope on a budget. That extra magnification coupled with the HUGE amount of info you can pick up with the HUD DMR reticle makes it a very valuable tool. Having a top dot for the true 1x in a pinch is also a necessity for me.

On your point about “1 go to rifle”, that’s my philosophy too. An 11.5” with an Elcan Specter on it. But, there may be times when I need more magnification and want more velocity.

If I build a shotgun, pcc, and a rifle, on one chassis, it is an SPR?

A 16 inch barrel is 500 yard capable with 5.56. a 1-6 LPVO is capable of doing 500 yard distances with training. Maybe a 1-10 if you want good ranging beyond that. And the original mk12 rifle I believe had a 16 inch barrel to do 500 yard things effectively. Anyone reading this please correct me if I'm wrong about that. But the mid taper, semi heavy barrel profile is a multirole profile that enables you to do a bunch of stuff. Basically, a 16 inch general purpose rifle with slightly more powerful glass up top and even without a bipod would be great for doing just about everything well enough to get by and be a good middle ground for use in those scenarios. Weird, it's almost like a general purpose rifle can do general purpose things. That said, this would be a great concept for forward operations and shock troops to use because it's a do-all rifle concept and you need a do-all rifle for those kinds of things.

I think it’s a solid concept but I’m biased as I have built a similar rifle. Currently it’s a 13.9” with a Vortex 2-10 FFP (at some point I want to add the secondary dot but not now due to budget) running a cloud defensive light, Griffin Explorr Can, and I would like to add a bipod as well. Ballistically the 13.9 will work out to 600+, and locally I’m pushing it to get a 310 yard shot at the range. I collected some Chrono data comparing the 11.5, 13.9, and 16” rifles I have, as well as suppressed/unsuppressed with 4 silencers on the 16”, my main takeaways were: 1. The 13.9 only lost 60 fps vs the 16” (2,975 vs 3,035) with Winchester M193 55 grain. 2. On the 16” rifle the data was so close, with one suppressor averaging below unsuppressed (the shortest can, 4.4 FPS below) and the the other averaging as much as 75.2 FPS faster (the longest can but also a .46 cal can) I don’t know that a suppressor truly has a measurable impact on velocity. 3. 62 grain 223 was only at 2,652.2 FPS with the 13.9 whereas the 16” was at 2,723.8, I feel like that’s kinda slow but I would like to get my hands on 556 loaded 62 grain. Overall I like how the 13.9” shoots suppressed with a mid length gas system and it’s been relatively reliable except for the CMC trigger.

@@DinoNucci Brass and Hop know what I mean, theyve done videos about this. GPR = General Purpose Rifle. SPR = Special Purpose Rifle (this video). 18, 16, 14 are barrel lengths. Pretty straight forward with the context clues in the video

[@nikos6220]

In one of your videos you mentioned that you would give a bullpup a try. It would be great if you were to take a 16’ 308 a Desert Tech MDRX and put it against your SPR in a course with targets that reflect impact energy (even water jugs will do the trick). Take the Mantis handguard to cover your bipod needs on the MDRX. And I am sure you as a lefty will enjoy the forward eject feature. That would be an awesome video.

[@BornSisu]

I have been through many rifle set up’s andI have to say i completely agree. I prefer a 16” accurate enough 556. I do like the capability of running a light as can be bipod a small white light, a LaRue QD Mount “ SOLID” and actually a SFP LIGHT OPTIC. Currently running VX 5HD 3-15 SFP HTMR RETICLE. The thing is 19oz’s. I can see my reticle at closer ranges and have practice making damn sure I’m on 15 so I can hold if need be but If I have time I will always dial. My rifle is a lot lighter than some of my previous “DMR” set ups. I love it

[@BandAid350z]

I see the application for this as more suburban DMR, but I get the concept. Flex into an urban carbine setup but with the reach of (close to) an SPR. A GPR of sorts, but a nuanced position that is distinct.

I've found that an 18" to 20" fluted barrel will get you all the weight savings you need without significant penalties in heat, accuracy, etc. A 13.5" handguard will provide enough 'rail-estate' and additional weight savings.

@@lordhellfire153 I have the 16" VHS, I personally have no interest in the longer one. The trigger pull is long but its not as bad as some people make it out to be.

Lastly, cowitness height is ~1", so go for a 1.1" optic height. Scope rings for an MPVO or LPVO are easy, and the Primary Arms prisms sit at 1.1" on their low mount.

[@andreivaldez2929]

I built something like this a while back: 20" heavy barrel, rifle gas and stock, 2-12 scope, binary trigger, drum mags, and a QD bipod. Ended up being mostly fired in semiauto as a pseudo SPR but I was basically going for what I thought would've been cool for a "M27 for the regular guy".

I’m getting 2745 with that same load at 1400ft elv. 10 ft from the muzzle from a Faxon 18” so not sure whats up with your barrel. Dropping barrel length is the right choice for 99% of people who are likely to engage 150 yards or less however when you are trying to maintain terminal performance beyond 350yards that extra 1-200 fps is going to extend the ability of a projectile to fragment or expand an additional 100 yards. Look into the terminal threshold of the bullet you are using and you’ll find yourself reconsidering shortening the barrel when you realize you’ve got an over gassed .22

I had concluded long before the Super Special Forces Delta Ninja SWAT Seal style SBR rage started. That a 14.5 or 16 inch carbines were where it's at. For the general purpose rifle. Even before Crane had said anything about the, "Recce Rifle" concept. Crane/NSW wanted the Mk12 to be a 16 inch gun. I served with the two guys that did all the requirements for the M27. Gunner Mortimer was a Squad Leader with another platoon in my company. And was the lead on development at 29 palms. And Gunner Wade and I went to Boot Camp together. And he was a CAAT platoon guy with 3rd Battalion, 1st Marines. When I was a lowly boot 0311. He was the East Coast lead on tge development of the M27. They both had concluded a 16" carbine was optimal. Especially for the general purpose aspect of things. Infantry sh*t. And Infantry sh*t is going to be the order of the day every day if'n this all goes south.

Kind of an old video but I actually just built a 13.9” 6.5 Grendel with a sons of liberty match barrel. It’s so much easier to maneuver than my 18” faxon 6.5 Grendel actually in early testing it’s more accurate too. Using my go to round 107 grain smk I’m only losing about 80fps. Still getting right around 2600fps. My 18” was a musket with a suppressor. This setup with the suppressor is just a touch longer than the 18” with a muzzle brake. I know 6.5 Grendel isn’t the most popular cartridge but I’m deep invested with 5 rifles chambered in it with plenty ammo + reloading supplies but I also have 5.56 rifles if for some reason ammo availability/compatibility is ever an issue I can just swap over

Noticed you mentioned the PSA AAC 77gr ammo. I bought a few boxes of their OTM and their Sierra Matchking. Goal is to compare the 2 and see if paying $15/box vs $12 is worth it. Same applies for their 69gr with same offerings. I’m guessing the extra $ isn’t worth it. Time will tell!!

Similar for me, I have a 9” .300 upper so decided I might as well go a little longer than the typical 11.5” to a 12.5”. Was going to go with an 18” for my SPR/GPR build but now I’m second guessing that. Not sure how true the talk on the internet is of 12.5” getting close to 14.5” velocities.

I like many have a 18" DMR or SPR. But I also have 16" rifles with a LPVO of 1-6 and routinely shoot those to 300 yards with no problem. I've shot very accurately with the 18" guns I have out to 725 yards. Each have their own purpose for sure. The weight of a goof 16" barreled rifle with some type of glass with a loaded 30rd mag is going to weight almost 10 lbs. The 18" is going to be even heavier and most likely have a bipod to boot. The topic is an interesting one we could all sit around and talk about, but honestly having a DMR for an urban situation in this country with the likely hood of actually using it that way is so remote, it's almost not even worth talking about.

Sorry to be that guy but i'm gonna be that guy. I certainly don't mean to be a dick about it because I do enjoy all the content You and hop put out. My take from this is: Basically with this build we are back at a basic infantry grunt rifle build. A GPR or whatever acronym cool guy phrase one wants to use. It's a 16" do-it-all rifle/carbine. Neither a DMR or a CQB type build but it's versatile enough for almost any of the plethora of situations one can find oneself in. With a bit of planning, zeroing and dialing one can probably stretch it out to 500meters and hopefully have a decently lethal shot. As for room clearing it's not optimal but definitely doable. Been doing room clearing in narrow apartments with a 18", fixed stock HK G3 and although it's a bit clunky it's mostly about training and adapting the gear to the situation. The optic on top is what makes it sort of stand aside from maybe current issue standard grunt rifles that mostly use RDOs but from what i've heard standard issue rifles these days are being fitted with LPVOs/MPVOs aswell. Took that from your video "Who Has The Better LPVO? Army Vs USMC". Anyways, keep up the good work! Cheers
