What complete lower will work with this upper?
Phil W on May 1, 2018

I recently purchased an identical upper for a friend and he used a standard mil. spec lower to complete his rifle. So I would say as long as your lower is mil. spec. it should work with no problems. By the way my friend was very satisfied with the look and the construction.

Hope this helps.

Great upper
My first AR build. Paired with a Blackhawk lower (also From PSA). Parts fit together perfectly. Have taken it to range twice thus far and have put about 400 rounds through it thus far with no feed or ejection failures with inexpensive ammo (both .223 and 5.56) Accuracy is good though I am still getting it dialed in and figuring out what ammo it likes best. Love the way it looks too.

Handgaurd walks off
This is a nice shooting upper and is pretty accurate with both 55gr. and 62 gr. ammo. That being said, the aluminum handgaurd walks off after 20rds. and leaves a larger gap between the receiver and handgaurd with every shot. After a few mags the handgaurd will fall off.

I reached out to PSA customer support 2 weeks ago and they advised I torque the screws (which I had done everytime it walked off). I still have a rifle thats handgaurd falls off and PSA has been unresponsive on the repair.

Looks good shoots great, what more could you ask for.
When the upper arrived I opened the box, the first thing that I noticed was the box was lined with egg shell foam to protect it. After a few different loads I found a couple that would shoot sub minute groups at 100 and 200 yards. Haven't had time to extend it beyond the 200 yard distance yet, but am impressed so far.
