AR15 Build Kit - 5.56mm (16" Nitride Barrel & 12" M-Lok Handguard)

$669.99
SKU:
5561617(B)-MLOK(12QC)-BK

Description

Get your hands on this mean-looking AR-15 and hit the range with MOA groupings. Then brag about having built it yourself. This build kit gets you quality AR parts chambered in 5.56mm NATO with a lightweight (M-LOK) free-float handguard. With this kit, we added a little more: We threw out the standard lower parts kit and replaced it with an Anderson LPK. That means you get a polished, stainless steel trigger and hammer that cycle your rifle smoothly with clean breaks every time.  ust get some mags, a receiver, and ammo, and add the backup sights or optic of your choice.

What’s Included

This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock. It does not include the component to make a firearm: A stripped lower receiver. Pair this rifle kit with an AR-15 80% lower receiver and AR-15 jig to fabricate a receiver, sold separately.

New builder? This guide explains 80 percent lowers.
