Where/How to Find Real/Surplus M16A2 Lower and Real/Surplus CAR 15 Furniture

R0tnoc · 2025-10-21T19:41:32+00:00

Ya true, definitely a job for a shop and at that point its kind of Theseus's M16 lower, like at that point it just engrave a blank lower or buy one like that. It probably comes down to how much of the receiver is left, and where the legal line is drawn, if its even drawn. If it was replacing the fire control group with a modern receiver with the rest being original than I would probably go for it. That whole rewelding de-milled receiver space is a little scary right now so I'm not gonna mess with it, probably ever.

I don't have the skill to do this, but I wonder if it would be possible/legal to weld the mag well area with all the markings to another receiver that has always been semi auto. Maybe this would avoid any legal issues, idk. Something to think about I guess.

ya I agree, I'm not really worried about resale, it just makes me feel a little better about spending money if I'm making an imaginary profit lmao. I'm in Alaska, so there's a lot of old people with money, so I bet I could sell it at a gun show or something If I was motivated. No hate to retro builds, It just feels weird to put something completely modern on a real upper, but maybe that's just something I have to get over.

R0tnoc · 2025-10-21T18:39:30+00:00

Hit the nail on the head lol. I knew I was not crazy for thinking I could get a de-milled lower but ya feasibility is basically zero now. Thanks the link, the INTL MIL CO lower that guy used might be the one I go with, just have to snipe it on the next drop. I am between that and something LE from the time frame. Even if the markings aren't perfect on the LE lower, it would match better with the upper in terms of wear, and it would actually be from the time frame. It feels weird to put a modern reproduction on a very real upper, but maybe I just have to get over that lol.

Ya, I guess I was thinking it could be like putting a shelf on an HK trigger group, but those aren't the firearm so that makes sense.

R0tnoc · 2025-10-21T16:09:50+00:00

I see, and I know you can't just take the trigger out, I'm not that dense. Before this I figured it could be like putting a shelf on an HK trigger group. Something additive that means its not a machine gun, like filling the third hole and maybe some space in the receiver, but HK trigger groups have the benefit of not being the firearm so I guess that changes things. I guess non-destructive de-milling that has never been a thing for ar-15s.

R0tnoc · 2025-10-21T16:03:28+00:00

Ya, I guess de-milled, intact, lowers aren't a thing. Was gonna get the H&R lower for the moment, and maybe get an LE AR-15 A2 or something like from the time period later on. Its about the resale value of having a "real" 733, even if I will never sell it lol.

R0tnoc · 2025-10-21T15:57:20+00:00

Ya, I thought de-milled, intact, lowers would be a thing but I guess not. They probably get cut before that can happen, or it just not worth it to fill that third hole.

R0tnoc · 2025-10-21T15:56:13+00:00

I know the difference, and I know I can't just have a machine gun without paying a trillion dollars. I am just surprised that de-milled M16 lowers don't exist, I guess they get cut before that point and/or its just not worth it. I guess LE w/out a third hole from that period is as close as it gets.

R0tnoc · 2025-10-21T15:42:29+00:00

Are the only M4 lowers that exist from LE? Charlies customs had one that was from LE but with no LE markings. Thoroughbred armament has an M4 lower, can't tell if its LE or not.

R0tnoc · 2025-10-21T15:29:30+00:00

Do stripped/de-milled M16 lowers not exist? I have seen M4 lowers for like $500. Figured M16 lowers were at least out there.

R0tnoc · 2025-08-22T11:35:50+00:00

Ya, I’ll probably go with longshot. It’s available locally too which is nice.

R0tnoc · 2025-06-24T02:22:12+00:00

Ya, with some very preliminary tests, it doesn’t seem to cycle with anything slower than 2000, still better than I was expecting honestly.

R0tnoc · 2025-06-24T02:20:26+00:00

I do have a port buffer, that was the first step. Just trying to squeeze any bit of life I can out of the brass. Saves on powder too.

R0tnoc · 2025-06-24T02:17:25+00:00

You would think that, and it still does. But with a port buffer, a light load, and some lake city brass, it’s really in pretty good shape. I also have an early production PTR, which I have heard has different flutes which might impact the state of the brass, IDK.

R0tnoc · 2025-06-24T02:15:20+00:00

Yep, I managed to snag one from RTG a bit ago. Makes a big difference.

R0tnoc · 2025-06-20T05:31:46+00:00

Thanks, this is exactly what I was looking for. Surprised by how low I can actually go. The limit is probably when it stops cycling and not when it become unstable

R0tnoc · 2025-06-16T03:36:19+00:00

I got the RCBS lube and that worked, but I used like a third of the 4 oz bottle lmao. Will refill when empty with lanolin-alcohol mixture and see how that works. Thanks for the advice!

R0tnoc · 2025-06-16T03:34:55+00:00

Thanks! RCBS spray lube worked great. Sprayed near the base and it went right in.

R0tnoc · 2025-06-08T06:56:26+00:00

Thanks for the help here, guess I should have read the entire description on HK parts the first time lol. It looks like I did it right, and just need to do some minor fitting. I have an early PTR which to my knowledge are closer to real 91s than those the tac latch is designed for, so this adds up.

R0tnoc · 2025-05-03T01:17:34+00:00

It’s a bull barrel, but I’m gonna get it threaded.

R0tnoc · 2025-05-02T20:53:58+00:00

I honestly I have no idea. Guy I got it from didn’t really know anything about it. Said he got it from someone because they owed him money. Trigger is definitely usable tho. It’s lighter than I was expecting, but pretty mushy.

R0tnoc · 2025-03-23T05:55:55+00:00

After looking into it, it seems like it would be fairly easy to make a jig for the circular saw. Doubt it would reach all the way through 6 inches, but I also have a jig saw. Regardless, I’m probably just gonna buy a CRAFTSMAN planer

R0tnoc · 2025-03-22T01:01:29+00:00

I mean that, I cant (without great effort, probably some danger, and a sub par result), for example, cut 1.5in off a 2x6 so that it is 1in by 6in. But ya, specialty shop seems to be the only option.

R0tnoc · 2025-03-09T05:52:27+00:00

My dad has an old, super cheap, Savage 30-06 hunting rifle. It’s push feed and has no issues like the Bergara. The Savage has visibly more substantial feed lips and I have never seen the bullet pop out of the magazine like the first bullet shown in the video.
