For the money a very good deal.

I purchased this in 2024 for a build for my son’s birthday. I build an Anderson lower and attached this upper which worked great. It fits nice and tight and shoots like a dream for the money I spent on this build. There are better uppers for sure but for $199 sale price I feel like I made a great purchase. It was on sale. I used FDE in all my accessories and parts to make a nice looking rifle. And as always PA was great with shipping and offering great choices for items to show off this rifle. My son is going to love it, his birthday is a few months away. Can’t wait to go to the range with him.

Pretty good super slick with a nitride bolt

by -

Really smooth action with a nitride PSA bolt and green arms warhammer CH shoots very well I’ve got a red dot on it probably shoots about MOA I’ve had no issues like the other reviews say.

No QC Issues

by -

I'm very happy with this purchase. I'm not seeing any QC issues. No burs. Fitment is good on a Rise Armament lower receiver. Gas block is aligned. I've had no issues on the range. A great entry into the AR world for me.

Junk do not buy

by -

I ordered this upper on sale and I see why it was so cheap. The fitment between the upper and 3 different brand lowers I have is extremely loose fitting. Enough that it almost feels like the bolt carrier is catching. I would not recommend buying this part, spend a few more dollars on a better brand. 1 star is too good of a rating

Terrible QC and workmanship

by -

Save your money. I would not trust this upper to cycle or shoot safely whatsoever. It’s obvious these are machine assembled without any care for quality control. One of the roughest cut handguards I’ve held including stripped screws. Sharp edges and burrs all over the place that will cut your fingers up without gloves. Barrel was all scratched up and finish coat gone. Gas block not aligned or centered. I was honestly shocked how poor quality this upper was vs. my $200 PSA upper that is flawless and backed by lifetime warranty. Radical makes PSA look like Gucci. This thing is a liability waiting to happen. I have spoken.

Looks good

by -

Received My upper the other day looks and feels good very light weight even with the bcg. I only have two concerns one is that the handguard seems to have smaller dimensions than the upper receiver itself and the top rail of each is not sitting flush with each other and I can see the gas tube. The 2nd is when I mounted my optics they seem lop sided/crooked especially the two that both sit on the receiver itself as of the metal is warped but that could just be my eye playing tricks. Range time will tell but otherwise it feels and looks well built for the price. Will update after range time.
