For the AR builder who wants the most accurate, compact, functional, and lightweight 300 Blackout Pistol Upper, look no further. Our 7.5" Pistol Upper with Free Float Quad Rail features an all-mil-spec construction with classic Picatinny rails that allows for plenty of attachments. With an included bolt carrier group and standard charging handle, this Pistol Upper ships ready to fire, no guesswork and no extra steps needed. A 1:7 twist rate and pistol gas system offers the perfect balance of stabilizing lighter supersonic 300 Blackout loads, without sacrificing the ability to reliably shoot heavy subsonic loads.

Mil-Spec Quality and Accuracy

Our 300 Blackout Pistol Upper features a mil-spec 4150 Chromoly Steel barrel with M4 feed ramps for guaranteed feeding and reliability. Because our barrels do not use chrome lining, you'll enjoy superior accuracy, too. We heat-treat every barrel to a hardness rating of RC 28 to 32, creating stronger rifling that's more resistant to wear than any other barrel on the market. This negates the need for chrome lining entirely, while still providing superior durability. This Pistol Upper also features a standard Flat Top M4 receiver, housing a quality, mil-spec charging handle and chrome-lined bolt carrier group. Everything is manufactured to ISO 9002 quality control standards, ensuring the highest quality Upper possible.

The only part of your AR pistol that's considered a firearm is the stripped lower. This upper is legally not a firearm, so we can ship it directly to your front door.
