Part 1 - LMT Enhanced Bolt Physical & LMT Enhanced BCG & Barrel Autopsy

[@SmallArmsSolutions]

That carrier is not designed for that caliber or pistol gas system. The bolt if fine. The can track timing is different, designed to increase dwell time in a 14.5 in internal piston barrel. Use standard carrier.

[@starxlord9856]

Wrong the bolt was undersized check out his part 2

[@lancekilkenny721]

​@STARxLORD Chris is NOT wrong about the redesigned cam pin geometry. It was designed for 14.5-inch carbine length gas systems Ala the M4. The dwell time in a pistol length gas system is totally different. The fact that this particular bolt was out of spec in no way negates Chris's original comment.

[@bretc1012]

Sooooo.... I looked at lmt defense description of the enhanced bcg. "This carrier group was designed to function effectively in full-auto, suppressed, and short barrel weapon systems,..." From what I understand, 1) definitely not for a piston ar platform (if that was what you were trying to say) and 2) it is to increase dwell time, in short barrels as well. I agree, I don't think it is needed for a 300 blackout rifle, and could be a problem... but would be sweet in any other sbr as dwell time is an issue in a mk18 ect... If I am mistaken, please let me know.

[@swatbwana]

Chris is 100% correct about the carrier

[@bretc1012]

@swatbwana then my question is... Is the dwell time bad in a 14.5? Enough that someone would make an enhanced bcg specific for 14.5? Edit: I watched an lmt video on this. Yes, you are absolutely right. The intended purpose is for carbine length gas, 14.5 upper. I thought 11.5 and up were good with dwell time... I'm just a sad confused man 🤔

[@yankeefist9146]

My credit card is getting nervous after seeing all the gauges I think I need. Good video, thanks!

[@blackcheetos]

I love how he shows all the fancy tools but also the tests you can do without anything but the weapon itself

[@doktorfaustus]

The LMT "Enhanced" BCG was solicited by Crane and engineered by LMT to address parts breakage/reliability issues on a very specific platform-a military M4 with a 14.5 in. barrel and Carbine length gas system; the further you stray from that platform, the more chances you take that it will be a detriment to reliability rather than an enhancement. While the bolt is just generally strengthened and stress relieved in ways which should provide increased durability in any AR-15 platform (occasional spring replacements notwithstanding-they are wear parts after all), the carrier is another matter. LMT altered the cam path in a way which optimizes timing for that M4 Carbine, and the change is not universally compatible. The Navy didn't even end up buying these EBCGs because they didn't work in rifle-length M16s. I have no idea if it's a good choice for a .300 AAC with a pistol-length gas system, but it seems like without a lot of data to support that use case, you're just rolling the dice.

[@gwpattrick]

That's what I'm thinking also. There cam pin i, think is smaller. This might be a proprietary bolt carrier, but might not be the enhanced one. Without looking and all

[@marzcapone9939]

@Your Internet Buddy Yep, I have the same 10.5" 300 blk barrel from LMT, and ran a standard carrier and bolt. I even have an 11.5" in 5.56 and also run a standard carrier, but with the LMT enhanced bolt. No need for the e-carrier in those.

[@luiscolon921]

My understanding is that the e-bcg was failing in the rifle length intermittently and only under automatic fire. I've been running this in a suppressed Daniel Defense 9" 300BLK pistol gas setup. It runs flawless and noticeably reduces the emitted gas coming back towards me. I probably wouldn't have picked it up if I wasn't running a suppressor with a fixed gas system due to the price.

[@JTTTTT850]

That's not true at all. All it does is relieve stress on the 2 lugs that sit next to the extractor. watch the video. And if that was the case why did LMT sell it in this configuration? Clearly stated at the beginning of the video it was a LMT factory built gun.

[@doktorfaustus]

@@JTTTTT850 I'm afraid you do not understand the system as a whole. The enhanced BOLT is designed to relieve stress on the lugs, but the enhanced bolt carrier also differs from a milspec design, and in a way that is not helpful for all gas systems. As I said in my initial comment, the enhanced bolt should be compatible with most 5.56mm ARs, and provides some additional durability, but the enhanced bolt carrier group is only an "enhancement" in certain specific configurations.

[@honestguy6345]

Great video...I appreciate you demonstrating the clear differences and variations in manufacturing and tolerances. Please consider wearing gloves in the future.

I have one of the LMT ebcg's and it runs flawlessly. But I am using it with a 14.5" with a carbine length gas system. Works both suppressed and non, without an adjustable gas block. I just throw an H2 buffer in it with the can on. Runs like a champ.

[@JohnZ556]

Cool! That's what EBCG was made for, a 14.5 or 16 inch 5.56 with a carbine gas system. The delayed unlocking and faster pressure release in a 300aac probably just created issues that won't exist in the first place.

[@jackfern7102]

Hello from the PNW, Chad, Thanks for the really informative videos, I'm self taught but a bit ocd when it comes to tolerances & gauging also but I don't have your breadth of knowledge or experience. I'm going to forgive you for giving away one of my closely held sources, Pacific Tool and Gauge, lol! While watching some of the SOTAR Bolt & BCG inspection videos, I saw these videos, part 1 & 2 on the LMT enhanced Bolt (2) & Carrier, followed through by checking the headspace on the .300 Blackout Barrel. I really appreciate the thoroughness of your instructional video here as I have a LMT MRP Upper w/ 10.5" Barrel in 5.56x45, I'm using this for a build project with an LMT Defender lower Receiver & I have 2 Complete LMT enhanced Carriers w/ enhanced BCG's. I'm signed up for back in Stock notifications with a few Companies for the 14.5" LMT MRP Barrel w/ Carbine length gas tube. As this is the set up I want to run and I believe the 14.5" barrel with the enhanced Bolt & Carrier should offer the durability, reliability, longevity & hopefully accuracy I'm hoping to achieve w/ this build project. I'm likely not going to use the 10.5" Barrel but will use a XM-177 style flash hider/moderator pinned & welded for NFA compliance, since I have a couple in my Shop. But I was writing this comment on the headspace checks that you did on the .300 Blk. Barrel, I planned on headspacing the Barrels before final assembly & test firing. I have a set of go, no go & field gauges but I was very impressed by your design and set of go, no go & field gauges. In your video on Why do we gauge so much, you stated that you started making these for people who were in your classes and at the request of friends & others who had seen them and mentioned that you would be selling them. I have checked the School of the American Rifle website and as yet haven't seen these headspace gauges available. Will they be offered through the SOTAR website in products or is this set something you do as a custom order? I would really like to purchase a set for the 5.56x45 but would also be interested in versions for the .300 Blk. , 6mm ARC , for AR platform build's. I would definitely be interested in a set in .308 Winchester perhaps other Cartridges if you expand your offerings. The modification of base's of the headspacing gauges was sheer brilliance exercised through experience & into physical form, well done. I'm definitely interested in the set of bolt tail gauges, the taper pin gauges are of interest as well. I noticed in the comments one from the Gentleman from smallarmssolutions which was a good tech answer, I thought. Their channel has an excellent video "The Buffer - Theory & when to use what Buffer. I found it really interesting, having worked at Colt and being well versed with the exhaustive testing @ Colt for the AR platform, he's in the video said he has a thick tech sheets folder regarding the results of testing of buffers at Colt and provides a really detailed and cautionary breakdown of the various weights & types, when, and for various gas systems, barrel lengths, weather condition effects ect. I would recommend the video for others such as myself who believe safety to be a critical part of a build project. Just have to say I'd prefer watching these types of gunsmithing, technical videos to the Golden Globes or Academy Awards any night of the week! lol! I guess I am a bit of a firearms geek as charged. Anyway thanks again sincerely for the giving us all a better understanding of the AR platform, it's internal operating systems and functions. I believe it is vital for people considering the popularity of the Rifle to be familiar with it's internal operating systems, components, tolerances and what's compatible & safe when making changes or alterations and what's not. As I mentioned I'm seeking reliability, durability, longevity and accuracy as well as safety and compatibility of parts when building these Rifles for myself, and there's far too many people who claim expertise & experience with firearms making video tutorials, how to videos ect. It's important to separate the "Wheat from the chaff." I think the School of the American Rifle and the information you so thoroughly provide is one of the absolute best resources for working on the AR platform & firearms in the Country. Our here in Washington State we're also fighting several restrictive firearms related measures in the State House and Senate and we have some great firearms Rights Organizations based here in WA. State. We have a great legal Firm, WA. Gun Law that does up to date videos on firearms Rights, Laws and Legislation in the State, neighboring States across the Nation & Federally and keeps us informed, armed with information to participate in defending our Rights and Liberties as well as the Second Amendment of the Bill of Rights under both the US Constitution and State Constitution's. Be well and keep up the Great Work. Sincerely, Jack Fern, Tacoma, WA.

Question for you Chad, I didn't see you check for throat erosion on this 300BO barrel??? That was going to be my guess right next to head space issues.

[@ScottKenny1978]

If you're having failures, it's better to get the rifle in the conditions it is failing in. Sure, rifle being dirty may be the issue, but an AR should be able to go several thousand rounds between cleanings with no loss of reliability.

[@ditzydoo4378]

I think I've seen less grunge on a truck axel then there was in that LMT carrier. Apparently the owner doesn't yet know of the importance of cleaning after use.

[@toki89666]

I don't think its necessary to clean an AR-15 after every use, you didn't explicitly say this but it was implied, I think a cleaning every 500 rounds is more than sufficient. But yeah that BCG was disgusting, mine doesn't look like that even after 500ish rounds. Perhaps suppressor use here?

[@ditzydoo4378]

@@toki89666 Yes, cleaning any gas driven system after use, be it an AR, or gas operated shotgun is a must if one is to prevent corrosion of the metal, or Carbon lock. after use simply field strip the gun, flood with Gun-Scrubber, scrub area's with stiff "Nylon" brushes (no steel) re-wet then blow out with compressed air, takes all of 5-minutes. Apply a quality "Gun" specific lubricant such as Ez-Zox (*no WD-40, it's a water displacing agent that is designed to dry over time*) and allow to cool to room temp before placing into a Sack-Up silicone treated gun sock and storing in the safe.

The biggest take away from him I’ve got is that it’s not about what brand is best or whatever it is but you HAVE to do your due diligence in checking your own products once assembled and make sure it works. I have seen everything from the low end brands pass with flying colors and even the “Best” brands fail horribly. You have a sample of 1 and it could be good or bad but you won’t know until you check. This is why he will not make a recommendation to buy a specific brand bc he has seen them all fail to some extent.

[@Gunner-73]

I think an explanation of the field gage and No-go gages should be explained. I will try to simplify; go-gage means the barrel headspace is with-in tolerance, No-go gage means it out of tolerance but if it closes on , it will still fire but needs to go to a gun smith for repair. Field gages were designed for the military to allow for extra tolerances of acceptable wear in combat but there is a danger of case separation and case damage. Brass life will definitely be shortened if firing a field gaged fail rifle.

[@wingracer1614]

Closing on a go gauge does not mean headspace is in tolerance, it just tells you it's not too tight to function. It could be way to big which is why you also need to test with a no go gauge.

[@pwrbomb1970]

For those who shoot steel case ammo, any magnetism is detrimental

[@ScottKenny1978]

If you shoot steel (or bimetal jackets), you can scrape fragments of steel off the ammo. If your bolt etc is magnetic, those fragments stick to the magnetized parts and can jam things up or just slow things down enough to cause issues. Those little fragments will also cause excessive and uneven wear on parts over time, which also causes reliability issues.

[@erichironsson8592]

No. The BCM is phosphate coated on the outside, and chrome-lined on the bolt bore. It will handle gas better over time than the Geissele which is "nano" coated. Which probably just means DLC. Which is a fine enough coating, but the chrome lining in the bolt bore will retain dimension amd gas efficiency better.

[@JH-oh1in]

[@CertifiedBullpupHater]

Unrelated topic but quick question. What is the is the issue with having “too heavy of a buffer”

[@tylerxi3828]

From my understanding, the heavier the buffer, the more resistance behind the BCG. Therefore, an over-gassed rifle will be less violent, but less reliable with a heavier weight buffer. An under-gassed rifle will have short stroking issues with a buffer that's too heavy. It's easy to think of it as a continuum: Heavy buffer=less recoil, more risk of short-stroke failures. Light buffer=more recoil from higher carrier velocity, this can cause parts failures prematurely. What I do is load one cheap steel round into a mag and fire it. Then I increase the buffer weight until the rifle will fail to lock open on a steel .223 rem round. Does that make sense? Once you fire a properly tuned gas-system you won't go back!!

[@CertifiedBullpupHater]

Tyler XE I’ll probably try the same. I finally found an a5 buffer system on SOLGW website( their sold out everywhere) but they only had an a5H3 buffer so I just bought it

Any idea how many rounds on the bolt with weak springs?

[@CubanPete]

the bolt had 2-3 mags stuttered through it before its first trip to LMT due to cases sticking and failing to eject, pretty sure i was shooting Fiocchi ammo. Went at least 5000rds of Federal AE 5.56 on a suppressed 10.5 fine before I then dropped in a .300blk barrel and every case I could find stuck. I tested it with 5.56 again to see what was up and this time all I had was PRVI, cases kept sticking, sent it to lmt, they changed the ejector spring like the first time. I doubt I put another 200rds on it before sending it to Chad because I was seeing the exact same issues I had seen a year earlier. Round counts are approximate given its been a year since some of these events happened.
