6.5 Grendel Rifle Kit (20” Parkerized Barrel & 15” M-Lok Handguard, Side-Charged) w/ 80% Lower (1:8 Twist)



Who dares to say the AR-15 can't reach 500, 600, even 800 meters? Not you, because you're picking up this kick-ass 6.5 Grendel build kit, accurized to the bleeding edge with mil-spec parts and a match barrel. Grab that optional 80% lower and you'll have all the parts required to build a black rifle tack driver with a single box o' parts.

At the business end you're getting a classic A2-type flash hider and standard threads for any brake or comp. The barrel's forged and beautifully cut from 4150 CMV, all mil-spec and coated with a Parkerized finish. A free-float M-Lok handguard provides space for your favorite tac-light, grip, and/or bipod. Forged receivers complete the look with a Type III anodized finish. Inside is a full-auto BCG and single-stage trigger that breaks clean like glass. Out back, a typical forged buffer tube and M4-type buttstock makes for a comfortable, light, and adjustable length of pull.
