Will this work with a standard AR15 lower that has a 9mm magwell adaptor? Also is the BCG a full auto cut on the bottom that can be used with m16/fostech echo 2 FCG?

Do the ets glock mags work well in these uppers? Does the bolts lock open or do they close when mag is empty?
Thomas L on Nov 15, 2018
BEST ANSWER: Bolt does not lock open and the Glock (made by Glock not knockoffs) 33 round mags work great. I load them down to 32 rounds to be sure they seat when doing bolt forward reloads.
Can this item be ship to California, specifically, Orange county?

Will this upper work with a Foxtrot Mike lower???
JESSE J on Aug 24, 2019
BEST ANSWER: Hey Jesse, in the description for this upper PSA states:

"To be used with Palmetto State Armory 9mm lowers that use either Colt® or Glock®-style magazines."

I got the PSA 9mm lower for it, and it works perfectly with GLOCK magazines.

PSA PX-9
I bought the upper and lower separately, and opted for a 16" stainless steel barrel and the EPT fire group with Magpul furniture. The barrel is polished stainless steel, and everything looks and feels very solid and fits perfectly with the lower. No rattles, no squeaks, no play, everything fits nice and tight. Colors match perfectly as well.
The scope is a Burris RT-6 1-6x24 and Fast Fire 3 red dot combination. I bore-sighted the scope for 25 yards, broke in the barrel while adjusting the scope for a 50 yard Zero, and then shot this group at 50 yds. The polished single stage mil spec trigger felt very smooth to me, like a mil spec trigger after a couple thousand rounds of firing.
At 100 and 200 yards groups started drifting farther apart, which is the shooters fault, shooting while resting the carbine on a bag on my open car door.
I am very impressed with the quality of this PSA PX-9, and have already bought another PSA AR15 5.56NATO.
5x8 inch group at 200 yards, no wind, all shooter!
PSA PX-9 16" stainless steel with GLOCK 17L, both 9mmx19mm Luger
1x2 inch group at 50 yards after sighting in the scope

My shooting setup, not the most stable, but adequate on a rare overcast Arizona day

AR-9 Review, ammo issues!
This is the second one Ihave built and it may not be fair to judge as it's not really broke in. But, after the first trip to the range it seems to be a little picky about the ammo ....we're shooting? It stove pipes regularly vs my old one that's shoots like a champ! We'll see?

Good quality as expected
Along with the upper, I purchased a PSA Colt mag lower. Accuracy, fit and finish are good. The only reason that I don't give it 5 stars is the need for an extended buffer. Stoppages, ranging from spent brass being inverted in the ejection port to spent brass being dispensed into the trigger assembly.
Since adding an extended buffer, function has been perfect. A second addition, although not necessary for function, is to use an AR10 buffer spring, which dampens recoil.
This problem is common with a number of manufacturers and the problem is easily resolved. Why not add an extended buffer at the factory?
Would I buy again? Yes. Absolutely. I done my homework and was aware of the issues. The solution is simple and the PSA is a good bang for the buck.

Great upper
I mated this upper with the Glock/Magpul billet lower. It is extremely accurate and easy to handle. The PCC chamber works well and ran 100%. The only problem I had was the ejector came loose in the lower tying up the gun. I re-engineered the ejector and my life is good now. I'll run this gun in the Area 2 PCC Championship in February.

Great little shooter. May even try some close action hunting. Sure burns up ammo quick.
This is my 3rd PSA gun. You won’t beat the quality for price anywhere. I got a PSA lower for this upper. You can get exactly what you want with PSA. Kind of like designing your own gun. See photos but I found Factory ammo that shoots thru the same hole all day long at 50 yards. 9mm isn’t really a rifle round, but neither was a Thompson machine gun. I am still all about accuracy and hoping I can get results at 100 yards out of 9mm. Would be happy at 75 yards. Enjoy no kick, quiet rounds, cheap ammo and rate of fire. It begs to be shot fast.
All 10 shot groups at 50 yards.
All 10 shot groups at 50 yards.  This barrel loves the Liberty +P 50 grain, 2000 fps loads.
Finished weapon.
