[NEW] 5.56mm AR 15 Rifle Kit (16" Nitride Barrel & 15" M-Lok Handguard) w/ 80% Lower - (1:7 Twist)

Please Note: Given the current demand for this product and supply shortages, your order may ship with a black hammer and trigger or a stainless steel hammer and trigger.

Get your hands on one of the sleekest, most get-down-to-business looking rifle kits in our catalog.  This bad boy comes to you chambered in 5.56mm NATO, the same caliber as our military's rifles, and has been upgraded from a standard lower parts kit to an Anderson LPK.  That means you get a polished stainless steel trigger and hammer that feel smooth and break clean pull after pull, cycle after cycle.

This kit comes with everything you need to complete it too.  You supply the tools for the build, and finish it off by choosing the backup sights or optics of your choice.  Then just grab some mags and ammo, and get to slinging some lead at your local range.

Barrel: 16″ carbine-length with black nitride finish, chambered in 5.56mm NATO, 1:7 twist rate, .750″ low-profile gas block, 15″ free-float M-Lok split 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 Remington, 5.56 NATO, 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).
