YHM stopped selling them a few years ago, not sure if Windham Weaponry still sells them (they don't sell to WA anyways so it's a moot point) and Colt's through Brownells are never in stock.

Other than putting in an order to Specialized Armament I can't think of any place that sells the real thing.

Real thing = phosphate finished, red Nylok patch, drain hole, and nice smooth machining.

I’ve wondered about those… They might be worth a test order.

Though I have ordered A1 stock screws and A2 sling swivel screws from them in the past and they weren’t quite correct.

Their A1 stock screws were black oxide finished with no red Nylok patch and their A2 sling swivel screws were correct in every way except they didn’t have the yellow Nylok patch.

I have gotten some good small parts and such from Damage Industries.

Good luck.

It’s been a while since I checked their site, but I don’t remember them ever carrying stock screws of any type. Not even the sling swivel screws for their M4 stocks.

Edit: Just checked their site. Looks like they now carry A2 sling swivel screws and M4 sling swivel screws, but no A2 stock screws.

Hmm, sorry about that. I checked and bought a couple of A1 stock screws from JSE Surplus, so they might have A2 stock screws.

ETA: Doh! Reading is fundamental. I totally skimmed over your mention of them in the OP.

AR15sport.com has them listed also.

I put in a test order for a few A2 stock screws from AR15sport a couple years ago. They were not as advertised unfortunately (no red Nylok patch, black oxide finished and very rough machining + they were rusty). Sucks because I had never received anything that bad from them before.

I bought some from PSA about two years ago that were decent, but no loctite on them was my only complaint.

Bought a few of the Brownells branded A2 stock screws to check out. They are at least better than the picture on their site, lol. No Nylok patch of course, but the thing that bothers me the most about them is that I'm pretty sure they're black oxide finished.

I've ordered parts from them for A1 rifles and they were good to deal with. Only thing that makes me a bit hesitant to order A2 stock screws from them is the picture on their site. Might not be an accurate representation of what they're actually selling though.

I have the same feeling about Amherst.  Many years ago, they had genuine GI parts.  But, looking at their website today, a lot of their parts look like modern manufacture, and with black oxide coatings instead of parkerizing.  I could be wrong; I'm just going by what I can see.

Those look like the A2 buttplates I got from RRA. They have a wide bevel on the bottom edge of the opening in the buttplate to accommodate the thick polymer trap door.

Never really heard of "TACFIRE", but if the picture of their A2 stock screw is accurate it looks like the real thing.

Well that's a nope on the CDNN A2 stock screws... I just received my test order for 10 of them and they are either blued or black oxide finished with no Nylok patch. Also, the taper on the shoulder is a bit off compared to the real thing.

So I'll see about sending them back for a refund.

That's too bad.  I was hoping for maybe some leftover Bushmaster or Anderson goodness.

Have you tried contacting some of the smaller vendors that have been around a while (Model 1 Sales, M & A Parts, etc.)?  They may have some older inventory.

Numrich with the “DPMS” brand A2 stock screws would probably be next on my list to place a test order.

It was either M & A Parts or Model 1 Sales that were among the first places I noticed that stoped selling parts to WA (not that I blame them). I’d need to ask them about that again.

Edit: It was M & A Parts that won't sell to WA. > Link.

I was in a building a few years ago and inside on a shelf was a box of hollow screws. I thought to myself, "Self, I know what those are." Thousands of them. I seem to remember a bit of rust. They are probably still there.

Specialized Armament lists them for ten bucks.

Yep, I know they have them... Though at that price it keeps me looking elsewhere.

What's even more nuts is that Brownells was selling them a few years back for $11.00 each. And though they eventually lowered the price to $8.99 it's still hard to want to buy them at that price.

I wish I had stocked up more than I did when YHM and Windham Weaponry were selling the real thing for less than $3.00 per screw.

It looks picture perfect, but it was already mentioned that PSA’s picture isn’t what they are actually sending out (no Nylok patch).

However, if everything is correct about them except for not having the Nylok patch, I’d go for them. Unfortunately PSA won’t even send so much as a hat to anyone in WA.
