The Radical Firearms .223 Wylde barreled upper is made from high quality materials so you can build an accurate rifle. The 16” barrel is machined from 416R stainless steel with a heavy profile and a mid-length gas system. This combination of features makes for a consistently accurate and soft shooting AR-15. Further adding to the consistency is the FGS handguard that is free floated to prevent contact with the barrel. Attached to the end of the barrel is the Zero Impulse Muzzle Brake to reduce felt recoil and muzzle rise. The upper receiver is machined from forged 7075-T6 aluminum with a black hardcoat anodized finish. It is fully assembled with dust cover and forward assist, all you need is bolt carrier group and charging handle and you have a complete upper receiver group. Attach it to your lower receiver and head to the range.

Super Accurate and awesome Upper!

by -

I purchased this upper hoping to give me almost the same accuracy that I have gotten out of my Ruger 556 MPR 0.25MOA-0.75MOA and it did! I got 4 55 gr. V-MAX Hornady in the same 0.3 MOA hole, the fifth (actually the first shot) was 1/2" off to the 11 o'clock of the 4 rds. group! at 100 yards. I owned couple of Radical Firearms and I am totally an huge Fan!

A good accurate upper for a good price.


This upper is accurate (though I haven't done more than function test so far) and reliable with either 223 or 5.56 Nato, except when I used a "brass catcher" bag, which caused some brass to hang up. Removing the B.C. fixed the problem. I went through about 50 rounds of each caliber. I like it so far.

Best Upper!

Outstanding! after sighted it in at 50 yards using a Truglo 1-6x24 Omnia 6 scope, I went to the 100 yards range using the tip of the cross hair reticle as designed by the Truglo scope, and my first 4 rounds landed in the same hole pretty much, after all the rounds landed it left behind a 1/2" hole using 55gr V-Max Hornady! Then I bought an awesome PA 4-14x44 FFP and shot a metal popper 3 rounds and left a one solid mark where all 3 rounds landed pretty much in the same place! This is as accurate as my Barnes Precision Machine upper .223 Wylde 1-8 16" medium contour barrel but cost me almost 80% less. I sold the BPM upper and finished my ar-15 with an Anderson lower with lots of goodies! scope included and fully ambidextrous, magpul furniture, and I have less than $1,000.. I paid $850 for the BPM upper, never again! Radical Firearms I am your biggest fan! Thanks PA for making it happen
