Your people? I don’t think he cares.

I bet. Size matters especially length. This is 1.625”x12” and sits about 4” back over the barrel. It sounds very good in person.

It literally made it quieter per his testing. It’s tested same way each time and showed it metered quieter. Nobody puts a meter in direct line of the bullets path.

Thanks John,I want to try the 165gr again. It’s just for fun and quietest output possible. If I had the cash(I always say this..) I’d love to try my 5” SA Prodigy 9mm. A threaded barrel is over $275 so it’s not in the priority list but I believe 1911/2011 are said to be great suppressor hosts. 😮

@coal_tactical Faster burning powder will achiever better suppression especially in longer barrels and/or than while using slower burning powders. Lower muzzle pressures too. Faster burning will also slightly reduce the velocity as well. For instance, titegroup is about 30 fps faster than clays, the very next faster burning powder on hogdons burn rate chart. Welcome to the wonderful world of reloading.

@@DingusDangus42069 thanks man! I appreciate it. I’m not a fan of Modular’s with a ton of “baffles” or “sections”. I think a 2 piece modular is fine and handy but a can built with like 9 separate sections seems a bit overwhelming if they get seized together from carbon lock. Hope to have more random content as usual as time goes on. I have a lot planned just not the time to do it or money to build my projects lol!

It really is. It isn’t going anywhere and can still be found just about anywhere. Unlike 300blk. Some gun shops don’t have it and you’re stuck reloading. Not everyone wants to do it either.

147gr Federal FMJ. Got a 500rd bulk buy.My handloads definitely test better for noise reduction. But these are good enough.

@@arm_usa Thank you for the info. Yes, the prices are much better for bulk buy. I get at least 2000 rounds every time. Last time I got 4000 rounds of the 125gr CCI Blazer FMJ. I've also got 1000 rounds of the "Federal Premium Law Enforcement 9mm 147gr HST Hollow Point". I've tested both ammo with S&W FPC suppressed with Rugged Obsidian 9. The 125gr CCI Blazer FMJ is much louder. The noise level of the 147gr ammo is tolerable.

@@lakesidemfg3552 check out the Part 2 Gordon video. I change a muzzle device and it made a huge difference on performance.

@ 140s still pretty loud. Guess I can’t expect magic

@@lakesidemfg3552 if I had it bored for .22 instead of .30 cal it might’ve been a smidge better or high 130s. There’s definitely better designs that will be an improvement on my form 1. Possible to get lower 130s with a 556 but it’s gonna take a lot.

@ sorry I didn’t listen to the entire video. Yeah that totally makes sense. Pretty cool form 1.

There’s a chart online for the drops and it’s not great. Anything below 10.5 lacks power. But…this package suppressed still has more penetration and power than a 9mm+P+ coming at ya. Without a suppressor it’s pretty worthless IMHO. 😂

@arm_usa Definitely. 300 Blackout is supposed to be decent in a short barrel. I'm having a hard time deciding on a caliber for an AR pistol...

@ I hear ya. I’m hoping to buy a cheap BCA 7.5” 300 blackout barrel to compare soon. I will do some low light testing like this and suppressed testing aswell. Hope in the next month I can help ya decide. I have no chronograph anymore but I’m sure there’s online data of the ballistics for comparison. Keep an eye out for the video. Probably NOT be a “short” next time.

@arm_usa awesome! Which suppressor are you using? Thinking about getting one or doing a form 1.

@ this was a YHM resonator K 30cal.

Your Suppressed shotgun is sick AF! I’m sorry for the lack of my email reply. Just been hectic in life. 😅

@arm_usa That's what I figured bro, I understand

Tom,thanks man! I can just give you that AK style funnel to try out. Keep it. Send me your info via Email or on the 308 forum. [email protected]

@@netpackrat I got a mount conversion done by Eccomachine.net. He’s the man. He will make it feel useful again by converting it to standard HUB threads 1.375”x24. Best thing I ever did.

Thank you! Those are all great calibers in 10.5” barrels still.

@bricethaice not all of them are blowback. There are DI 10mm and delayed uppers too. I am not aware of any mag conversions. Most use a 45/10mm glock lower. I'll also point out that in a 16" 10mm carbine barrel, with the right load of No.9 powder and 155 gr bullet, you can see around 1775 fps averages. That's more energy at the muzzle than a 55 gr 223 traveling 2950 fps. So, while it's not a long range sniper gun, don't discredit it for a "get home" gun. Also wanted to mention, even with blowback, there's things that can be done with buffers if you're concerned about recoil. I don't know why so many people get hung up and think pistol caliber carbines kick hard. It's still a freakin' pistol round. Anyone that thinks pistol cals are uncomfortable to shoot, please for the love of God and all that is good, never ever pick up a shotgun. You'll HATE it !!

​@@utubegeneric ya 10mm is badass. ive never actually done a pistol cal ar (dunno why) but am aware that blowback sucks more because everyone comments about it, di would be the way to go. my thought process is if its an ar platform might as well be a rifle caliber, dedicated pistol mag lower kinda changes that i guess.

@@bricethaice lots of people say that blowback semi's sucks. Reality is a lot different. The pussification of America has been ongoing for a few generations now and at the end of the day, you're still shooting a pistol caliber. Putting a pistol cartridge in a shoulder fired weapon doesn't magically transform it into something it's not. I wonder how many old cowboys in the wild west complained about the recoil when they started getting their lever actions in 357 instead of 45-70. My guess, none of them and it's the same principle. Smaller bullet, less powder. less kick. Yet, here we are in 2024 where online forums are full of soy and estrogen wussies. Lots of what you read online about PCC's are just regurgitating foolishness. If someone says they can't handle a hi point carbines, you know not to believe anything else they say. Further, PCC's are one of the fastest growing markets in the gun world. Even S&W now have their hands in the cookie jar.

​@@utubegeneric Let me start by saying, I'm not trying to take a dump on 10mm pcc's but I want to understand your reasoning here. And this is coming from somebody who thoroughly loves pcc's. In fact I just finished my 8" radial delay ar9 build this week. Shoots buttery smooth. I don't think 10mm in that case is a good idea. For one thing, you should never use handloads for any defensive application as you'll destroy yourself in court....... if it comes to that. Secondly if you're using a 16" barrel it's no longer a pdw/truck gun. It's just a rifle at point. And even though a 10mm may produce more energy than a 5.56 with that barrel length. It won't maintain that advantage for long enough for it be a benefit. Based on my ballistic calculator reading, using a hornady xtp 10mm 155gr bullet at 1775fps you'll lose your power advantage over a 55gr 5.56/223 in under 25 yards. You also have to take into consideration ammo availability and weight. A 55gr m193 load is a few grains lighter than a 115gr 9mm fmj, and if that's the case, I don't even have to weigh a 10mm cartridge to find out which is heavier.

​@@hardlylivin6602 I wish that youtube hadn't deleted my previous comment. I'm not downing your response either. I would however like to mention a few things. Carbine length is generally classified as any barrel length shorter than a rifle. If we're talking about AR15, in this instance, that is 20". So, 16" barrel is still yet a carbine and why I referred to it as such. As for handloads, I always use handloads. I stopped buying commercial ammunition a decade ago (except 22lr simply because I still can't reload 22). Everything else including shotgun ammo, I load myself. As for overzealous prosecutors, we don't necessarily deal with that here. And even if I did, I would still use my handloads. Why? For starters, handloaded ammunition is not illegal to make. Is not illegal to possess. Is not illegal to use. Therefore, they are just as legal. So, the overzealous prosecutor should be made to have a harder time proving you broke the law by either making it or using it in a defensive manner when it's not unlawful. That's where having a good lawyer comes in. Nor have I ever heard of an instance whether store bought or hand made ammo tipped the scale either way in criminal court. Besides, there are commercial ammunition that loads to the maximum pressures on the market too. For that matter, if pressures or velocities were even a consideration, any commercial +P ammunition would be unlawful. They would be comparing pistol and rifle velocities in every trial. We both know that a 30-06 has more energy than any pistol caliber or many other smaller rifle calibers. Is that going to become the new "standard" of measurement for trial courts? I don't think so. People just twist themselves into knots sometimes. If you know of an instance where someone was convicted based on thee ammunition they used, I would be very interested in obtaining the court records to that case, so please share if you do. As for what I would use to defend myself with, I'm not limited to what I think some prosecutor would like me to use. I'd use whatever was available to me at the time. Flamethrower, cast iron skillet full of hot grease, knives, machinegun, fists, trebuchet, pistol, broken stick, shotgun. Bazooka. Drone. Feel free to let your imagination roam. As for your comparison about 223, where I live, I don't get really long shots. Most any shot I would take would be well within 100 yards. Actually would be more likely to be within 75 yards. I have a lot of bears, big cats, etc. I'm not opposed to anyone using 223 for their circumstances and situations if that's what they want. I have several 223's. I rarely ever use them though. I gravitate more towards bigger heavier bullets. They work better for me.

@@bricethaice always been a fan of these fat old handguards.

@@arm_usa i copped a troy 9" bravo quad rail recently cuz i like the 2014 vibes. i like the one u rockin there i had some like that, easy install wonder if i can find some for cheap still.

You like I mentioned the good ol’ 10mm? ;) I’d like to do one of those eventually.

@@arm_usa I do like that you're thinking outside the box. You load up 10 mil like you're supposed to, it'll leave a mark.

@@utubegenericI’ve always had one in a handgun but never in a subgun style. Currently only have a Glock 29. Would be fun to and very usable in a 7-8” barrel SBR setup.

Interesting,though never heard of it. What case is it built off of?

@@arm_usa10mm pistol case. Makes more sense than the .338 Arc.

@@ForOdin for the average joe it’s great. Plus,the money and engineering for garage guys might not be there so this is still king. I don’t think for me personally it’s worth it to dip into the printing aspect of cans. I enjoy my old school lathe and what I can do with it. To each their own.

@@nemoexnuqual3643 .22LR ,300blkout and a 350 legend. All suppressed of coarse in an AR15 platform. 38 special from a lever action suppressed is also freaking quiet. You can get subsonic ammo for all these choices from some big box stores like Cabelas and Sportsman’s.

@@MTMILITIAMAN7.62 I actually I don’t have 16” barrel anymore. 7.5,10.3,12.5,14.5 and 18” is what’s in the stable now. Bare muzzle 16” a while back I got about 164-165db if I remember correctly. With a Flash hider and they YHM on a 16” it did low 150s. Maybe a decibel better than the 7.5. It was way better for the shooter and at the ear was a tad better though. Testing this can on an actual 30 cal gun in 308 it also oddly gets similar results regardless of barrel length. There’s some difference but not a lot going to longer barrels. The “at ear” readings get a bit better along with less percussion.

@@arm_usa A 16 inch long barrel is not what I first thought of when I read, "16-inch gun". I was thinking of the U.S.S. New Jersey!! And there are suppressors for artillery too! For those that never realized that it a thing.

@@Kesssuli true. Would be the last AR I grab for anything. Especially in Unsuppressed form. That little can knock’s off some serious percussion still but it’s rough.

@@arm_usa Someone would guess that there is a reason why pretty much every law enforcement/military forces using shorter than standard barrels seem to have supressors installed on those guns. Im aware how much handy shorter rifle/shotgun is specially at hunting when going trough forest. But damn just normal birdgage flashider will remind you how bad it is to shoot rifle whitout protection which is pretty much impossible to have while hunting. And about last thing to use for anything you know that there is 8 inch barrel .300 winmag ? For shit and giggles i would guess😆

@@MinutemanMedic I hear ya. I actually would use this caliber over 300blkout. I like ammo availability and 5.56 prices better too. A 9mm shorty would definitely be handy with a 30rd stick too. The 9mm AR would be way better on the ears too.

@@arm_usa Yeah it's also that for truck gun where you're living out the LARP fantasy of zombies and rioting murderers trying to pull you out of a car, a 5" 9mm is pretty handy and probably won't deafen you as much as the 7.5" 5.56 since you likely won't have ear pro.

@@1GLO919 BK 2209. For measuring gunshots you’ll need a 4136 1/4” microphone and pistonphone for regular calibration. These components need to be had in order for it to function and meter correctly.
