I'm stoked on my Crusader lower! Can't wait to finish the build!

I bought a military contract overrun surplus FN A4 M16 upper and put it on an FN M16 Military Classic lower. It came complete with the Knights rail and the BCG. I call it my FN Military Classic +. Except for the lower not being full auto it is Mil Spec. Another way to get actual Mil Spec is by buying a military surplus parts kit. Unfortunately the barrel and the lower receiver are cut into pieces but you do get all the small parts.

“Mil-spec” isn’t always a good thing. Just look at the junk the US military bought from Sig. The M17/18 has problems

I don't watch Garand thumb much, so I must have missed the drama. Using a empty primed case, you can measure the before and after it is fired using a gauge.. I have never used a Tubbs action spring..So you are running a full length rifle action spring with a carbine buffer?? I just want to be clear about this..

Thanks for the video. Interesting topic and some useful information you've given out. Nice picture of the Lancaster WW2 bomber on the wall behind you. At least, I think that's the Lancaster that was flown by the Brits? I'm a fan of the bombers of the WW2 era, as My dad flew in the B-17, then in the B-26 Marauder in WW2 and Korea as a Bombardier and navigator. I have some nice pictures of a couple of his planes from that era, The Missouri Mule 2 in particular. What was the rifle you were holding, a Colt A2 carbine? I love the carry handles, especially the A1s and A2s. Thanks again and have a great evening!

Great info! Thanks SRT.

Have you tested the Luth-AR barrel chamber with a function gauge? I have never used or seen one on my bench. I have ring gauges to find the bolt tail O.D. size to find the tolerance between the carrier bolt tail I.D. bore to the bolt tail O.D. I prefer to find the tolerance between them rather than just the carrier bore size using a pin gauge..Many bolts have over sized bolt tail O.D. that will compensate for over sized carrier bores. I will also shine a light inside the carrier with a proper pin gauge to see how oblong the carrier bolt tail is. I also check the hammer spring strength (ignition energy) on high round count rifles using a depth micrometer. I like your idea of marking the barrel's gas port size on the barrel. I really enjoy watching how other armorers do inspections. Thanks for sharing.

I wonder why you went with a non CL barrel, with a Stormy Daniels sized GPD? Isn't .0625/.063 per TDP? I wish you could still get the Remington Defense Socom barrels. They were cheap. The two examples I had were not as accurate as the two Colt ones I have now. But were accurate enough. I'm not a Clone/Mimic enjoyer. I end up changing stuff. My Colt collection is highly sacrilegious to cloners. I carried a A4/M4 during the GWOT for a living. I like nostalgia. I have a F'ed up version of my service rifle. It started out as a Colt Competition HBAR. No threaded muzzle. It had the A3/A4 carry handle upper. Thats the reason I bought it. Marine Corps Times had a article with the Commandant General Jones holding the new A4. I went to the Del Mar gunshow and overpaid happily for that rifle. My roommate at the time was a armorer and he changed the barrel out for a new military barrel. He wanted the HBAR cause he shot service rifle competition. I refused to register it under the California Assault Weapons Ban and sent it to live with my uncle. He shot that A2 barrel out. And I retrieved it upon his death. I replaced the barrel with a Criterion 1/8 that ADCO re-pinned FSB to. And it has a 12 inch Centurion C4 rail. And a TA31/RMR combo with the ACSS Aurora reticle. It has a AO Precision BCG in it now. It's also the test bed subject for the Schmid Tool 2stage. Which seems to be pretty good. I have a hard time buying stuff from companies now. Knowing where this stuff comes from. I've had good luck with Anderson lower recievers. Mine are all newer. I had bought 2 of the Poverty Pony ones and one I sent back to Anderson and they replaced it.(Small mag well.) Then I bought a 5 pack of the no logo ones. They all pinned perfectly. And everything drops free. $194.00 for 5. 🤷🏼‍♂️

I agree, if you like this upper then I personally would build another m4 upper. Personally I like the centurion arms extended fsb rail system

Build another upper! Then you will have both!

Larue mbt2s they're solid triggers i had a geissele g2s previously and after a couple thousand rounds i couldn't tell any difference in pull weight or reset between a friend's ssae that being said the larue is almost identical in feel and pull weight as the g2s and I'm sure after a few more rounds thru it it will get even better like the g2s did

This is the first time ive seen your channel. Subcribed. Thank you

YSF fasteners on gas keys are known to sheer. Their fine for other applications, but not on the component that takes a beating. If you've got 3k rounds on yours, maybe whoever made those gave a shit lol. I know for certain Ruger uses them on their ar-556, and sfar. I'd never buy a Ruger AR for that reason.

PSA's assembly is were they lag big time imo. I've had good luck with the parts themselves, but I wouldn't use any of their products until that stuff is taken apart and put together again properly.

Where can the average civilian purchase tools for guaging things like pin-hole sizes as you've demonstrated in your other videos? Appreciate your content. I'm a stickler for precision and quality control so your videos are very helpful. Thank you!

That lower looks used, or poorly anodized

like your video quick question... have you had any experience with a company called Sharps? they make a BCG called fail safe BCG?

I like what you have to say but CHF is not TDP. They are button-broached even though the CHF is better.

I couldn't agree more.. I get asked the same question all the time too and when I don't give a cut and dried answer, I get the look lol.. When I try to explain head space, function gauge, bolt face, carrier, bore, etc, testing along with the fit and fitment, I watch their eyes glaze over...Then I will explain that price does not always guarantee quality or crap and that crap can even get through some of the best reputable manufactures, (even though the odds are higher it won't) is when I seem to lose them.. There is a lot of bad information being spread on forums and in UA-cam land that makes it even harder to educate.. It is channels like yours that can make a difference..Once again I enjoy your content and I always look forward to it, keep up the good work!

Thanks for video, plz check my comments from your PSA video. I would love to have a copy of your spreed sheets.

I really enjoy your information, it has been spot on..Were you at the Colt armorers class last summer at Gunsite by chance?

Great content.. I noticed the Aero M4E1 lower does not have the pivot pin detent bore oil hole drilled in the receiver boss..Glad I found your channel..

Thanks Brother!!!

Dude, found your comment on SOTAR's Facebook page. PLEASE keep making content. We need more of this in the AR UA-cam space. Chad does a wonderful service, but we need more of this. I won't name names, but I get so tired of "top five budget rifles", and then those videos don't bother bringing up material science whatsoever. Brownells did a video on cheaper vs expensive parts, and offered NO material science to back up anything they were saying. Lets actually explain why something is quality or not quality. Usually, the most elaboration I ever hear is "higher quality materials". Talk about vague and just plain unhelpful. Fantastic video man!
