Description

We took one of our most popular AR-15 build kits and swapped out the stainless steel barrel with the 1:7 twist rate to one that has a 1:8 twist.  Now you can pop rounds off with a wider variety of grains.  On top of that, we upgraded a lot of the stock parts to premium Magpul stuff.

You still get that ever-useful 13.5″ free float M-Lok handguard.  But now, you also get the following Magpul accessories:  MOE grip and trigger guard, MOE stock, angled foregrip, and MBUS sights.  All you need are mags and ammo, and you’ll enjoy range time with an AR that’ll give you a great shooting experience.

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, Magpul enhanced latch plate, castle nut, and Magpul enhanced 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).
