Can this be used with a standard carbine buffer spring and buffer?
Tom1365 on Apr 26, 2018
BEST ANSWER: This comes with a standard gas block. I would highly suggest you replace it with an adjustable as for me
it was quite over-gassed. I started with a standard spring and H buffer and it pretty much threw the brass
out at about 2 o'clock with a very harsh recoil. I installed an adjustable block with the same spring and buffer.
After tuning, it really helped the system function with brass at about 3:30 and much smoother recoil.
Can this be shipped to California?

Nice compact upper for the price
Mounted this upper on new PSA AR15 COMPLETE MOE EPT SBA3 LOWER. This makes a handy compact pistol with enough length of pull to shoot comfortably. Pistol length gas seems OK with no failures to feed or eject. I did notice most ejected cases were closer to 1-2 o'clock position rather 3-4 o'clock. I'm going to try a heavy buffer to see if that makes a difference. I like the slim hand guard and overall fit and finish.

Pistol length upper
After buying a 16" rifle from PSA and loving it I wanted a shorty. Great price and shipped quickly. I'll buy the matching lower next time.

Great Midsize Pistol upper!
You usually have to choose between 7" or 10.5" barrels for a pistol build. The 8.5" comes in as the perfect compromise. All quality parts and a nice light weight hand guard. The only drawback for me was the standard gas block on this pistol barrel caused over gassing. I replaced it with an adjustable and got it running much smoother. Otherwise a great upper!
