Description

For the AR builder looking for the perfect combo of a USGI-like Quad Rail Handguard and the new 300 Blackout chamber, you’ve found your top choice. Our Complete 300 Blackout Rifle Build Kit features a quality heavy barrel constructed of 4150 Chromoly Steel and carbine-length quad Picatinny handguard, housing a low-profile, carbine-length gas system. This unique setup allows you to easily switch from supersonic to subsonic loads without the need to swap gas systems or barrels. The simple but proven quad rail offers plenty of real estate in all cardinal directions to attach any accessory you want.

Mil-Spec Built, 1-MOA Accuracy on a Budget

Even though our 300 Blackout Upper is affordable, it isn’t cheap. The whole thing’s built with mil-spec ratings and features, including a gold-standard 4150 Chromoly barrel that promises 1 MOA of accuracy at 100 yards, M4 feed ramps, M4 Flat Top Upper Receiver, A2 Birdcage flash hider, and of course, a near replica of the military’s tried and true KAC RAS Quad Rail system. Our Quad Rail is even more improved, featuring a direct connection between the rail and upper receiver for a fraction of the cost. Everything is fabricated in the good ole’ USA to ISO 9002 quality control standards.
