It has nothing to do with the concept of the rifle itself and everything to do with nothing seems to standardized.

I bought a billet 80 lower last year sometime because it was on a huge clearance sale. I had no intention to build it as I don't really want or need one. Well then a complete rifle kit goes on sale and god dammit I might as well build this thing now. I'll have an AR10 for $600. So I finally got around to finishing the thing this weekend and I'm way unimpressed. I'm not calling either company out because I believe all parts are in spec for their design but they aren't very compatible with each other despite advertising being the same pattern.

1. The roll pin for the bolt hold open just fell in loosely. Did not need driven in.
2. The take down pins are too short for the receiver and so the detents don't engage correctly.
3. The rear take down pin I had to grind a flat spot on so it would even work with the lower contours.
4. I had to grind off and custom clearance the buffer tube so that the buffer retainer pin was held correctly and let the upper close on the lower. Without the grinding, the upper would not mate to the lower at all.

Then I get all that done and I can't fully rack the bolt because the hammer interferes too much. This might be my problem from the machining but I haven't verified that yet and the trigger group functions and appears to be in place exactly where it should.

So in short, fuck the AR10. This is the first and last one I ever dick with.

Nothing is wrong with AR-10s at all. Zero.

There are many different designs of AR-10s, get over it. Compare a POF piston gun with a standard "GI" AR-10. Or even compare a Ruger SR-762 with Ultimax type gas adjustment. However, the custom designs are only like 15-20% of what is out there. The special AR-10s are in the minority.

Your lower sucks balls and/or you should have known what custom pins and parts needed to be ordered which would work with it.

You make my point. With ar15's, I can throw an aero upper on a psa lower. I can throw a psa upper on an Anderson lower. You can literally use 15 different parts sources and they all work. I have several bullet ar15 80% lowers I've done and numerous forged ones too. Not a single issue. Then I do this bastard and WTF...

It's not a psa issue.

Bingo!


I've built, machined and shot numerous 80% AR10s. Mine with a PSA barrel is about a 2MOA rifle. Buddy of mine has a couple, one is Creedmore and one 308, which both are sub minute guns that regularly shoot out to 1000 yards.

Only one I've come across with any issues is a cheapo upper that is acting under gassed. Severely under gassed even with my spicy loads. I'm betting the gas block is canted.

something i didn’t know before i built mine, the key to ar10s is knowing there isn’t a single spec. once i started diving into the build and learned that i went easy mode and bought both receivers and parts kit from aero.

Shoot it if you got it to work. There are different designs as I mentioned in my above post which are not comparable with standard AR-10s. Who cares?

If you are building a private army or want to buy multiple uppers to slap on, then you should NOT have bought that custom lower.

OP has been on the board since ‘08 and can’t figure out how to put together a working AR-10? Tolerance stacking is a real thing and it’s why you stick with one manufacturer of receivers and BCG when putting together an AR-10.

Buying the upper and lower from the same company is key. Takes 95% of the problems out of the equation. Biggest thing after that is ensuring you get the correct pattern/height rail and correct mags.

Shot her around 500 rounds suppressed before it started to malfunction, I cleaned just the extractor groove only. No lube, popped it back in and she ran like a top. I took her to a two week observer/sniper school, she was drug through the mud and dirt. She was shot wet and dry. She was shot somewhat warm but mostly cold and a couple of times frozen. She didn’t stop, I finally burnt the barrel out and she still runs like a top. The new barrel is a DPMS pattern barrel.



This one had a FA binary in it and it ran like a top too but it was too expensive to shoot like that so out the trigger went. It didn’t malfunction either, it has a K can now…




Both of these have been reliable with all surplus, match and hand loads I’ve run through them….

My buddy says:

"Since there was less than 10,000 real AR-10s made, which contract version did your parts kit come from, AI or Colt?

AFAIK no or very few civilian made AR-10 parts fit the military AI or Colt guns.

If you're messing with civilian made .308 AR stuff, why not stick to one manufacturer?"

I got one of the first ones and know the designer.  Shot THOUSANDS of rounds, no issues. The adjustable gas system works very well and resembles the Ultimax gas system.

It was only discontinued because of the price drop of AR-15/AR-10 type rifles several years ago.

I don't think they suck, but they take a lot more research to get a good build if not buying all of the same companies parts at once. Even then you can get something like I have where I purchased a PTAC-10 lower years before I bought the PSA 6.5 Gen 2 upper. They fit together without issue and function is fine. They don't perfectly match aesthetically with the upper having an overhang that is covered by the PSA lower. For my 16" 308 AR, I used a Stag upper, lower, and handguard and everything matched perfectly.
