Is there a difference between 4150 chrome moly vanadium and the barrels that are described as just chrome moly vanadium?
Nathan L on May 10, 2019
What is the actual barrel length? Is the barrel 16 inches without the the A2 installed?
J S on May 3, 2019
Chambered for .556 NATO. Is this compatible with .223 Rem?
MikeB on Jan 8, 2019
BEST ANSWER: Yes this is completely compatible with 223 ammunition. I shoot both with the 1 in 7 twist it will handle the mid weight slugs very well. Hope this helped
Is the a2 pin and welded?
Evan W on May 8, 2019
BEST ANSWER: No. No need on a 16" barrel. You can remove it and replace with another muzzle device.
Will this upper be good for taking shots at 100-200 yards? Not expecting crazy accuracy but decent moa at 100 to 200 yards. Thx
Harrison S on Mar 23, 2019
BEST ANSWER: Yes, love how smooth it felt when I took it to the range the first time. A 16” Barrel or most is good up to 600 yards. You shouldn’t have a problem hitting 100-200 yard targets. Accuracy is all about sight picture, the right sights will give you that.
Will this work with an Aero Precision Lower?
George on May 19, 2019
BEST ANSWER: Yes it does. Works well too!
Does this fit the leapers super slim handguard?

Very pleased
I simply couldn't be happier with this upper. The fit to my PSA lower is tight, finish is perfect and shooting V-Max ammo produced sub MOA groups. What's not to like?

Great value!
This is my second PSA build, and I would recommend them as one of the best values out there. The quality is comparable to mid-level brands, but at a lower price point.

I appreciate the craftsmanship and quality of the upper.
I liked the price, I was looking for a free float 16" that wouldn't break the bank. Huge plus that it was mloc. Great value, great product.
