I'm new to building an AR15 style rifle. If you get a complete upper is a complete lower all you need to finish the build?
ZombieHorde on Jun 27, 2018
BEST ANSWER: Technically yes but you would still need a magazine
How will this matchup with a Smith & Wesson lower?
Greg B on Jun 23, 2018
BEST ANSWER: It will fit any mil spec lower perfectly.
What is the inside diameter of the handguard?
Dale P on Jun 11, 2018
BEST ANSWER: 1.25 inches
Does this have a flash hinder?
Martin E on Apr 13, 2018
BEST ANSWER: Yes, a standard A2 type flash hider.
What does this complete upper weigh?
Bill N on Jun 15, 2018
BEST ANSWER: Hard to say, upper now assembled into complete rifle. "Lightweight" is relative, the upper was not purchased with that in mind. That being said, it is a very nice upper at a modest price.
What is the gas port size on the barrel?
Mike from CA on May 8, 2018
BEST ANSWER: I bought the upper as an assembled unit, so I've never checked.

Excellent rifle for an excellent price.
Very accurate and reliable. I shot about 200 rounds of Barnaul .223 through this rifle on my first range trip. I am satisfied with my upper and lower. I also got my lower from PSA.

Great for my SPRish build, highly recommend.
Have put about 300 rounds through this upper. Using a P.A 4-14x44 with a Giessele SSAE & 77gr OTM I've nailed down sub MOA consistently. the lighter ammo gives me 2-3 inch moa. Quick ship on this order. Dissasembled, cleaned, polished and lubed as soon as I opened box. Went with this over stainless and I haven't been let down. Thanks PSA Would definitely recommend.

Some failures with 556 but not designed for that. Perfect 223 upper.

Great upper for a great price.
Great upper for the money. Functions flawlessly with the PSA lower I paired it with. Fit and finish is great. Will definitely buy another upper.

Great upper/warranty
Solid upper and great warranty/customer service. When I first took it to the range it had a failure to eject. Called PSA the had me a shipping label within minutes. Shipped back in about two weeks working like a charm with no cost to me!

Great Accuracy, Great Price
I used this upper for my first AR-15 build and it is super accurate. I have a Vortex scope mounted on it and it hits 12” steel at 400 yards with ease. Great so far I only put 200-300 rounds through it pretty light weight.
