Description

Want an AR-15 chambered in .300 AAC blackout that squeezes out a little more performance than a standard build but still comes with a budget price tag?  That’s exactly what we’ve done in creating this built kit.  You get one of our same great-quality builds, but some of the parts chosen specifically to give you a bit more performance, especially when it comes to the somewhat persnickety .300BLK caliber.

We start with a 16-inch parkerized barrel and give it a pistol-length gas system.  This gives the rifle a bit more dwell time per shot fired and fuller powder burn, which in turn provides for greater bullet velocity and action-cycling performance.  Mount the back-up sights of your choice, supply the mags and ammo, and see what this baby can do for you.

AR 15 Rifle Kit Details (Expanded):

Barrel: 16″ pistol-length parkerized steel, chambered in .300BLK, 1:8 twist rate, .750″ low-profile gas block, 13.5″ free-float M-Lok handguard, with an A2 “birdcage” flash hider.

Upper Receiver Assembly: Forged from 7075 T6 aluminum, hard-coat anodized in black for durability, features M4 feed ramps, and are made in the USA.

Bolt Carrier Group: The bolt carrier is made from 9310 steel and has a staked gas key and black nitride finish. The bolt itself comes complete with an extractor spring and O-ring insert.  It accepts .223 Wylde, 5.56mm, and .300BLK calibers (though you should NEVER attempt to use a caliber for which your rifle is not chambered), and is magnetic particle inspected.

80% Lower Receiver: Choose to receive a forged or billet Fire/Safe 80% lower receiver.  Our lower receivers are anodized to match the upper receiver perfectly, and they come ready for machining of the trigger pocket and drilling of the safety selector and trigger pin holes.

AR-15 Lower Parts Kit: includes all parts needed to complete the lower receiver including pistol grip, mil-spec safety selector, and trigger/fire control group.

Lower Assembly: comes with complete buffer tube assembly including buffer, buffer spring, six-position buffer tube, latch plate, castle nut, and butt stock based on original Colt design.

Charging Handle: standard size, made from 6061 aluminum.

Please note: This build kit requires that the builder complete the 80% lower receiver themselves, but that’s the rewarding part of the experience (and the only way to build your own AR-15 without the need of an FFL transfer or serialization).
