PSA AR15 Complete MOE EPT with adjustable brace Lower, FDE - 5165448739
BEST ANSWER: With a normal buttstock it will be considered an SBR you'll need a tax stamp if you go that route. It will be a AR pistol if you use a brace no tax stamp required
Can a suppressor fit under that handguard?
V L on Dec 9, 2018
BEST ANSWER: No, but the barrel extends beyond the rail anyway. So you could still put a suppressor on it.
Is this full auto?
Cody M on May 11, 2019
BEST ANSWER: No, it is not full auto. In order to possess a fully auto weapon, you must apply for a Class 3 license, or get a ‘Tax Stamp’. Fully auto weapons are heavily regulated.
Is this receiver considered a pistol length upper? I do not see the "pistol" reference in the product description.
David on Dec 3, 2018
BEST ANSWER: It's under 16in so unless you're making an SBR it's a pistol.
Is the hand guard a Midwest industries?

First attempt is a great success.
This is my first attempt at building my own ar. The fit to my Anderson lower was perfect. I’ll be building more very soon.

Truly beautiful upper, and great deal.
Purchased this upper to combine with a SBA3 brace, and I can say it is my favorite out of the four AR15s that I own. Pair this upper with a quality flash hider and it makes a great PDW. It is very light, but the setup i’m running also has very little recoil. I plan on buying a couple more for family.

Great Upper
Matched this upper with a PSA pistol lower and its been all good. Upper arrived in flawless condition in about a week, and fit to the lower is tight with no pin slack. Over 600 rds. down range without a problem. Highly recommend this upper!!

Excellent Quality
I originally purchased a 7.5" upper from PSA but then learned months later that I couldn't attach a suppressor as the warranty of the suppressor doesn't cover anything under 10.5" barrel. I then ordered this 10.5" upper and it runs flawlessly. PSA always has amazing products for an affordable cost. I have a PSA lower to go with this upper and I have never had a single issue. I reccomend anything manufactured by PSA.

Gas Block Leak
It ran ok, but I had quite a bit of gas leakage around the gas tube. After sending it back for repair, it seems to be ok now. Other than that, the work appears to be good. The gas key is staked well, and I enjoy the size.
