I wish to use this in NRA Service Rifle competition. What else would I need?
nite f on Jul 25, 2019
BEST ANSWER: Hello,

This is a 10.5" pistol upper. You would need a complete pistol lower for it. If you need a rifle, this is the wrong product to start with.

Best Regards,

Can Palmetto state armory confirm the steel type for this barrel? 4140 or 4150? It would be nice if it was just listed in the description
mikey on Jul 10, 2018
BEST ANSWER: Virtually all of their barrels are 4150. Just compare it to the majority if other ar pistol barrels, PSA sometimes forgets to add a few details.
Does the Nitride finish extend barrel life?
Gary S on Jan 22, 2019
BEST ANSWER: Absolutely. Nitriding resists corrosion and wear better than chrome and phosphate. Nitriding last longer as well because it is a treatment rather than a coating. As far as i'm concerned it is the best finish you can get for a barrel for durability and longevity but what do i know, i'm only a gunsmith.

Does this ship to California? And which lower does it work best with?
Greg B on Apr 5, 2019
BEST ANSWER: Yes, I've bought plenty of uppers and had them shipped to my door. The lower receiver (which this doesn't come with) is the one that requires an FFL. You're good to go! Remember you'll need BCG and charging handle to complete the upper. You need to remove the flash hider, install and pin a different muzzle break on this upper though to be compliant.

excellent build quality.
Precise fit to PSA's enhanced trigger SBA4 lower. I put a green dot sight on it and took it out to the range today. From a rest, shooting at 100 yards into a 6" flourscent dot I was getting 2.5-3" groups with 55 gr mil surplus ammo. This is as good as I need. Good work, PSA.

Really good
The 10.5" barrel is a good length to go with, dont go any shorter. I only gave it 4 stars because I changed the handguard for a Magpul carbine handguard. I also don't like how PSA keeps changing the price, just keep it at $150, and it will sell like hot cakes in my opinion.

Awesome pistol upper!
Never thought I would want an AR15 pistol until I saw Mrgunsandgear post a deal on this PSA pistol upper. Lucky for me, a couple weeks later PSA had a deal on their pistol lower. In my opinion, this is the perfect "truck gun". Love this little pistol!!

Love this thing!
This is a great upper for a great price. I have about 700 rounds through it so far with zero malfunctions or issues whatsoever. Definitely recommend this for a budget pistol build.

Nice upper and BCG. I would recommend over many more expensive brands. It shoots accurately.
So far so good. Looks like the original Colt MK18 Mod0. Shoots well at 100 yards with iron sights 3” groups off bench rest. Vortec optic should tighten that grouping. Using Magpul magazines not one Fail to feed or fire 100 fist rounds using M855 62gr ammo or with frontier 75gr match ammo. Cant beat that for the price $199 upper plus $59 BCG
