Brownells 75th Anniversary - A Shooting Heritage

Optimized For Long-Range Shooting; More Compact Than Standard Rifle Barrel

The Special Purpose Rifle (SPR) barrel replicates the barrel of the Mark 12 Mod X Intermediate sniper/designated marksman rifles used by some special operations groups. This 5.56 NATO chambered, 18" barrel with a 1-7" twist easily handles the heavier bullets needed for long-range precision shooting, while still offering a more compact platform than the standard 20" rifle. Constructed from 416R stainless steel and finished with a bead blasted matte finish. Rifle-length gas system provides reliable extraction at lower pressures.
