I’m sure when manufacturers who know you see your name on an order say oh shit, make sure everything is in spec we don’t want to look bad on KZbin. I think it’s great how some of the supposed highest quality manufacturers have parts that dont meet certain specs. Before someone says I’m an idiot I do understand when he says pass and fail doesn’t always mean parts are “ good or bad”

It is so diffucult to get screw threads in spec, especially turned threads that are plated or anodized. I have to approve so many deviation orders due to threads being out of spec. If the threads are not a critical characteristic that is called out on the CAD file, pass the part.

[@raydon14ify]

Very impressed with the gas block

[@ddesoto10]

Great video. Just an FYI. The military is requiring less tolerances in the threads of the buffer tube do to the fact that if dirt or sediment gets in the threads it makes it harder to disassemble. If the threads were of very tight tolerances as what your desire seems to be and you get dirt in the threads while in the field it makes it very difficult to disassemble. If you are just a range shooter and don’t actively shoot in an environment that would get the rifle dirty it’s a moot point. Again great video.

There is not a lot of videos out there, reviewing the LaRue- I am very glad and enjoyed this video very much. He is a walking talking master of firearms. I have had a LaRue stripped lower for a while now, and I am waiting on the extra key parts to arrive. I am excited that I chose a LaRue, but also, I enjoy this video EVEN MORE. He has no bias, and TELLS IT WITH THE FACTS AND PROOF.. I truly respect his work. I am so far inspecting my LaRue products and they seem to be very good to go. Lets hope it stays that way. PS, for the record, LaRue customer service is extremely professional and responsive. ( i can almost garuntee when they saw this, they did a deep dive into it not happening again. Cheers from the woods of Maine and thank you for your videos.

Very educational. I just replaced one of my gas tube, turned out it's slightly bend testing with the bc as shown here. Must've bent it by accident when I was tightening the barrel nut.

[@LRRPFco52]

When tightening the barrel nut, the gas tube shouldn't be anywhere near the work. There should only be the upper, barrel assembly, and barrel nut. Same for removal.

[@Mike-ls1yc]

I had a similar experience with my Larue gas block screws. I started to think they welded them in place.

[@AnAggressiveSquirrel]

[@geoffadams5004]

If when determining the poor fitment of the buffer extension tube threads, how do you remedy that? Is it just a matter of trial and error by changing out different assemblies until you find one that fits properly or is there a company that you can contact to request the correct class of thread fitment? I have assembled one or two rifles myself from parts ( not a particular makers kit but random parts but trying to at least from the same manufacturer) and noticed poor fitting buffer tubes and castle nuts also but just attributed it to “mil-spec” tolerances because I didn’t know any better. But after watching your videos I am determining to pay much closer attention to tolerances and start adding tools that I have been missing to verify proper fit. Thanks for all your time and effort in making these videos and for your wife also for filming for us too! You have shown me that I have obviously not chosen well in the past who to take advice from. Humbly I thank you.

[@Ghost17110]

Hey Chad, do you believe something like a BRT gas tube would be a good option for taming the gas on these barrels? Wouldn't require taking off the thermally fitted gas block for those of us who want to make the upper a bit smoother shooting and less gassy when suppressed.

[@akmarksman]

@Gamer Gamerson If I had a can, I'd probably pick up a bootleg adjustable BCG and call it a day.

[@kerberarms]

did you buy most of your tools or make them?

[@user-kw1xf4kg3i]

Have you ever tried using an electric soldering iron to heat up screws with threadlocker on it instead of a blowtorch, i think it allows for more protection from damage

[@80439]

I like to heat a spare allen wrench red hot with a torch and stick it in to heat the screw. Works great but ruins the spare wrench, of course.

[@johnphillips222]

I've heard of tips and tricks where home machinists cobble together unique tips for soldering irons. I know that gunsmithing operations cannot necessarily afford the tools and equipment we use for professional applications. I use a portable inductive heater, instead of a torch when possible. It is only $600 for the generic kit, and we can make specialty inductors in house. It provides a very focused and controlled kilowatt to the assembly or part. It is super easy to follow OSHA hot work rules, and smoke emissions are minimized. I usually get called names, but that is how we do it professionally. Torches can work. MAPP gas works better than propane. Rosebud tips work well for Oxy/Acetylene torches. Another option may be to put it in an oven. We use process furnaces, although it is possible to use a residential oven. As a Loctite certified engineer, note that 99.8% of all gun and gun accessory manufacturers use the wrong Loctite product or use Loctite in the wrong joint design. Loctite 222 should be the most common product for guns, but most people have never heard of 222. I hope this helps.

[@jimmyhernandez5203]

@@boinger1988 idk. I bought a Colt upper a few weeks ago and I need to take the time out of my day to call CS. The extension bore was nowhere even close to concentric, sloppy as all hell too. Failed the fitment test and one of my 3 lowers I can fit a .030 feeler gauge in between, where my other uppers are relatively tight. In the BCG bore there's tool marks EVERYWHERE and it wouldn't bother me but they're incredibly rough. My dog bone marked upper that I got from DSA for $40 doesn't have any of these problems. But Colt is supposed to be "top tier". What a joke. If you buy Colt prepare to have CS on speed dial.

[@Tyler-uc4ye]

Little more info on the dog bone uppers, they're manufactured by Demco under a contract with the DoD. So "mil-spec" isn't an excuse, I'd love to send it to SOTAR and have it gauged just to watch him snort some BC Powder just to get through it. Damned thing should've never left the factory and it wasn't the only one I seen like this either.

I thought you could not check the headspace with the ejector and the extractor still in the bolt. But, I'm not an AR proficinado either, just wondering.

[@michaellee213]

13:58 As an improvised workaround, could you just use some type of tape, like maybe plumbers tape, as a way to augment the undersized buffer tube threads? Or am I smoking crack?

[@pdlane43]

For removing a broken bit, is there anything wrong with a soft tap from a center punch? That always removes mine in one or two taps.

[@l800x8]

I guess it's personal preference on whether to break the finish on melonited bolt carriers wtih heavy staking, or preserve the finish with moderate staking? Seems to me that solid staking would be better given the heft of a bolt carrier. I'd never considered that as a drawback to that finish.

[@ryanpeck3377]

The issue isnt breaking the finish, its actually breaking some of the metal off. Nitriding can make metal more “brittle” and if you tried to stake it heavily the bit of metal you are trying to push into the bolt head could fracture.

[@l800x8]

@@ryanpeck3377 I thought that was only a surface treatment?

I got my 14.5 Pin and weld LaRue UU this week. i was not satisfied with the fit of the Buffer tube. I do not have guages. I just mocked it up with other tubes and it seemed like it did not have a tight fit. I emailed the dimensions to LaRue and they say its In Spec and OK. i might try vibratite. but I did order a BLEM VLTOR standard tube for 30 bucks with shipping. I think i will test fit that and make a choice. I am running it tomorrow AS LaRue sent it. but I did not stake it yet. just torqued. just going to shoot 25 Match grade rounds. I shot 20 rounds today using the HOWA break in specification. followed by two 5 shot 1/2" groups at 50 yards! and i was just shooting 62 grain FMJ reloads. Great accuracy and i am totally satisfied despite the issue with the tube. it might not be a problem. i will find out i guess maybe.

[@stevemcafee2747]

I was hoping for the same, but I respect Chad’s judgement in not pulling it off.

[@Ghost17110]

Really wish he showed it as well but it's understandable why he didn't. In my experience it's at least large enough that you need Sprinco Blue + H2 when using milspec ammo or maybe even H3 or H4, though I wish the data was out there on how actually big it was so I could consider installing like an BRT gas port insert or BRT gas tube.

[@stevemcafee2747]

Depending on Larue’s answer, I may just put an A5 system on it. It’ll largely depend on how receptive they are to righting this issue.

[@Ghost17110]

@@stevemcafee2747 Yeah, especially considering how the tube and castle nut came out an A5 is definitely a consideration. Luckily mine didn't come out that iffy. Is this your kit in the video? If so, did you notice that your bolt catch pin is a bit large? Maybe it's just the lower receiver I'm using, a Zev/Mega, but holy crap I've never encountered a harder bolt catch pin before. I got it in far enough that it's crossed the channel into the other side but it's still not flush.
