Palmetto State Armory AR’s - I’m impressed

[C-grunt]

I havent seen any of their lowers come with a H buffer. All have been carbine.

Would I buy a PSA as a defense gun or go back to Iraq? No. At least not without a decent amount of testing and parts replacement. That being said I have several complete PSA lowers and they run fine. I recently put together a rifle package for my brother in law with a PSA rifle, Vortex Sparc AR dot, light, and sling. Total cost is around 800 bucks total. Only thing I can find wrong with it was a carbine buffer. Switched that to a H. I still have it as he has not purchased a safe yet, and it shoots well.

It's funny, the chart is what brought me to M4carbine.net. I was in "US Autoweapons-LGS) in Scottsdale and they had it printed out and said, check this out. It was great for a newbie like me.

It was great for it's time. Let you actually make an apples to apples comparison. At the time "mil spec" was the most abused word in the firearms industry and every manufacturer on that list claimed to make a mil spec rifle.

I still think the "mil-spec" label is pretty abused still today. I've ordered a lot of parts that were listed as mil-spec in the description and I've been burned many times. Just about to toss a few A2 stock screws into the scrap metal bucket that are not in any way mil-spec as they were described.

Even the Aero Precision rifle buffer tube kit I linked to in another thread is given the mil-spec label, yet in the same product description it says the buffer tube is 6061 aluminum. Can't be "mil-spec" and 6061, or can it? I might be wrong, but I don't believe so.

How are they wrong?

I have one PSA upper...it has an FN barrel and hasn't been shot yet...it is a spare of a spare.

My PSA lowers were one is a stealth and one was stripped, CMMG and FCD parts were added and they both have Larue MBT Triggers. I believe I added a Sprinco Blue recoil spring and H2 buffers.

The assembled lower mounted to Sionics upper shoots very, very smooth.

A mil-spec A2 stock screw should be phosphate finished, and include a red Nylok patch with a drain hole all the way through the length of screw. The screws I received were black oxide finished, with no red Nylok patch. They did have the drain hole, but they also came to me already rusting due to the finish. They also just look to be very poor quality. Similar (if not the same) as these screws shown here. > https://retrorifles.com/buttstock-screw/

I can live without the red Nylok patch if the screw is good quality in every other way, but the ones I received were not as advertised.

You are not wrong, specified material should be 7075. I think most often the industry refers to the outer dimensions of the receiver extension, not the material used. As long as it fits a mil-spec stock they don’t mind leaving out crucial details. Same goes for the dry film lubricant that is supposed to be applied to the inside of the receiver extensions. Most “mil-spec” receiver extensions don’t have it. I’ve only seen it on Colt receiver extensions I sourced from Arms Unlimited. IIRC the one I ordered from another major online retailer did not have it, but it came in a bag with Colt printed on their inventory sticker.

Some of the Colt ones that Brownell’s sold a few years ago didn’t have the drain holes either, but that was during the height of the pandemic.

I got a couple of those drain hole-less Colt A2 stock screws from Brownells during that time. They didn't have the red Nylok patch either, but they were a quality screw in every other way. I still sent them back though since $11 per screw is nuts even if they had the drain hole and Nylok patch.

After not having luck with Colt's A2 stock screws through Brownells I found that YHM was selling A2 stock screws which met the spec exactly, then they had to go and discontinue them. Then I found that Windham Weaponry's A2 stock screws met the spec exactly, then they went out of business. So at this point it appears Colt's through Brownells are the only option... And that's fine if they are now coming with the drain hole and the red Nylok patch.

Any idea whether or not the ones from Specialize Armament comes with the red Nyloc patch?

I haven't ever ordered any A2 stock screws from them. Though I have ordered M4 stock sling swivel screws from them and they were indeed correct (though one of the 3 had obviously been previously installed and removed). I also ordered a single A1 stock screw from them and it was correct, but it was also very odd... It's like they had refinished it and applied their own thread locker patch. The threads were in bad shape and looked like they had been refinished over.
