If you want to shoot heavier loads in your AR-15, the usual 1:7-twist-rate barrel simply won’t do.  This rifle kit features a 16″ 416R stainless barrel with a 1:8 twist rate, making it more sell-suited for handling heavier grain cartridges. 

The 416R steel we chose for this barrel offers the smoothest, most consistent rifling out of any gun maker’s factory. You’ll hit sub-MOA groups with factory loads at 100 yards – if you’re good enough to take full advantage of this kit, that is. 

The lightweight M-Lok handguard comes with plenty of space for your foregrip, tac-light, and whatever other accessories have a place on your rifle.  And it’s free-float, so it won’t kill your accuracy.  A carbine-length gas system reduces felt recoil and ensures faster follow-up shots.  Plus, the upper assembly is pre-built and measured to spec, ensuring your rifle kit’s ready to fire out of the box, no adjustments needed.  …after you put it together.  So, what are you waiting for?!

AR 15 Rifle Kit Details (Expanded):

Barrel: 16″ carbine-length stainless steel, chambered in .223 Wylde, 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).
