Who says an AR can't reach out and ring 12" of steel at 800, even 1,000 meters? We don't because we threw together this incredibly accurate LR-308 rifle kit! Sporting a 416R Crucible barrel with the gold-standard 1:10 twist and enough length for optimal velocity, this LR-308 kit will allow you to confidently land .308 Winchester or 7.62x51 NATO confidently at distances you never thought you could reach. Each kit is based on DPMS' .308 platform, the modern commercial alternative to ArmaLite's original AR-10 design. This guide covers the two platforms in detail.

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.
