Mediocre Finish, Outstanding Performance

by

The finish on my upper was rough and felt weird in my hands, almost like 1500 grit sandpaper. However, I have had a zero malfunctions with my upper and I’ve put several hundred rounds through it so far.

This is a really good upper for a budget AR build.

High value

by

Had this for couple months now and it's been great added a microbest bcg , and a radian charging handle and put about 300 or so rounds down range and it's been great. I wish I would have bought two before it was out of stock

Budget upper

by -

Bought this during Armageddon for $300. Fits snug on my palmetto lower with no rattle. Get 1.5 moa groups @ 50yrds. Enough for combat. Carbine gas length kicks harder than mid length. It's a steal right now for $230.

Works, but fit isn't perfect

by -

My upper receiver arrived a while back. It is accurate, but the rail and the upper receiver do not line up. The rail on the handguard is almost 1/8" lower than the upper receiver and it won't line up.
Too late to do anything about it, but just a heads up.
