As long as you don’t change anything. It’s classified as a pistol. That lower needs to stay with that upper. I suggest that you check with your state regulations as well.
Does this include the pins to secure it to the lower assembly?
Pat R on Jul 31, 2018
BEST ANSWER: No, it doesn’t include the take down pins. That should already be on your lower or you can purchase separately. They don’t cost much for the set.
Jose P on Oct 14, 2018
BEST ANSWER: Of course it will. If you bought the PSA AR-15 pistol complete, that is the lower you would get. I also have PSA uppers on both CMMG and Anderson lowers. The only lower/upper compatibility issues are with the AR-10 styles.
Does the handguard have a QD slot?
Paul I on Jan 14, 2019
BEST ANSWER: Yes. You can see it in the picture
fully assembled with a lower, whats the overall length?

Very Nice Complete Pistol Upper
This is a very nice pistol upper. I appreciate including PSA including a Mil. Spec. Carpenter No. 158® steel bolt that was shot peened, high pressure tested, and magnetic particle inspected. The upper functions flawlessly using a H1 buffer in a PSA lower with SBA3 brace.

I took off one star because I had to return the original one I received. It had cosmetic and fitment issues. Thank you PSA for making it right in a very timely manner (less than 2 weeks).

Like I said, fit and finish, accuracy, etc. Excellent product, highly recommended.
This upper is flawless, especially at the price. After a couple hundred rounds a trigger pin took a small walk on me, but I just snapped-it back in and back-in-business. Something I should have caught on initial inspection, ny bad. It has performed flawlessly since.

Outstanding for the price
Has functioned flawlessly. My only complaint is that it's a little heavy.

Could be better
At 200 rounds the charging handle failed. It mushroomed out and locked the bolt in place. Took some persuasion to take apart and replace the charging handle. I was only shooting standard .223.
I don't like that the gas block is so big and the handguard so small that you cannot fit M-LOK keys between the two.
I also wasn't a fan of the barrel to handguard length ratio. It is EXACTLY as advertised but there is a 2" gap from the end of the handguard to my Strike Industries Cookie Cutter Comp. I wish there was another option for barrel length with the same exact setup.
I'm 280 rounds deep and I'm on my 2nd charging handle but all else is working well.

I like the price point and the looks. The best part about it is, it runs...

Great little unit for price.
Mounted up easily and was well oiled. 100 rounds through so far. No problems. MLoc rail system doesn’t have a lot of room between gas block and rail for certain fixtures right over block( end of rail).
