The Radical Firearms AR-15 upper receiver assembly comes ready out of the box to attach to any Mil-Spec lower receiver. It has a forged M4 railed upper, so you can easily attach scopes and red dot sights to the MIL-STD rail. The upper receiver includes the bolt carrier group, MIL-STD charging handle, ejection port cover, and forward assist. The barrel is 16" of 4140 Chromoly steel with a Melonite coating and is attached via a steel barrel nut. The barrel has a 1:7 twist, designed to stabilize heavier 556 NATO and 223 Remington ammo at intermediate ranges. This twist rate will still stabilize standard 55-grain FMJ ammo as well, so your range time won't be affected by not being able to find 62 grain Gold Dots. Attached to the heavy SOCOM profile barrel is an A2 flash hider. This complete upper receiver is an excellent addition to your AR-15 build.

Repeat Buyer

I love the first one so much, I bought another one. Both are mated to AP M4E1's. As expected, since it's a SOCOM barrel, not for the weak arms when mag dumping since it's heavy but heat-wise, all good.

The first one I bought is flawless and aligns perfectly with the lower. The second, not so much. No issue with functions and operations but the second one is somewhat a few mm off to the right and out of tolerance while locked into the lower receiver. It doesn't seem to have any negative impact on the gun operationally, but it is noticeable when I run my fingers through the part where the upper mates with the lower and it bugs the crap out of me. Making me think twice, or thrice if I should continue to buy a third one. Hopefully, the quality on the first one was not a fluke and I just happen to get a "blem" version with second purchase.

Purchased the keymod version back in 2018. I have a spikes nickel boron bcg in it and she sits on an anderson lower with an alg trigger. have beat the piss out of this gun. Accurate barrel even when she gets hot. Shoot mostly xm193 and xm855 as well as a fair amount of steel case and it has been extremely reliable. Can remember any malfunctions that werent from user error or dud ammo. Does have some wiggle on top of the anderson lower but isnt real noticable and hasnt caused any issues, i solved the problem with one of those 2$ reciever wedges and shes locked up tight. Only other complaint is the screws holding the handguard needed some locktight to keep from backing out. But other then that, for the price you cant go wrong. Highly recommend if you dont care about gucci brands and just want a dependable rifle.

excellent

Accurate, easy to assemble to lower

by -

my 1st build, easy to assemble parts, the lower is from Palmetto because it was only $50, The AR kits and parts made in USA and I use .556 nato, It shoots very accurately without any adjustings, targets at 100` are on center. Really happy with this purchase.
