LR-308 Rifle Kit – 20″ Stainless Steel, Fluted Heavy Barrel, 1:10 Twist Rate with 15″ M-Lok Handguard

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 7.62×51 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.
