Got a talent or even a beginner’s know-how when it comes to building things?  Wanna build your own old-school looking AR-15, but don’t wanna screw with rounding up all the parts and tools yourself?  Well check this out.  With our Ultimate AR-15 built kit, you’ll end up with a classic looking AR-15.  The only difference is, ours has that flashy stainless steel barrel.  Plus, our Ultimate AR-15 kit now includes your choice of the Easy Jig Gen 2 Multi-Platform with Tooling or the 5D Tactical Route Jig PRO with Tooling.

To build your AR-15, all you need is either a drill or drill press.  Then when you’re done, all you need to supply are the mags and ammo.  It’s 50% simple to build, 50% classically awesome to look at, and 50% a blast to shoot when you’re done.  Yeah.  It’s 150% win.

AR 15 Rifle Kit Details (Expanded):

Barrel: 16″ carbine-length with stainless steel finish, chambered in 5.56m NATO, 1:7 twist rate, .750″ low-profile gas block, CAR-style/M4-style fixed 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).
