Details

The 13.5" free-float aluminum handguard is lightweight and features Magpul® M-LOK® slots at the 3:00, 6:00, and 9:00 positions. A shortened top rail improves grip access while retaining Picatinny mounting sections front and rear.

The flat top upper receiver with Picatinny rail allows easy mounting of optics. It is crafted from 7075-T6 aluminum forgings, with a 9310 steel bolt and chrome-plated carrier and gas key for enhanced longevity.

The Ruger® Elite 452® AR-Trigger is a precise two-stage unit with a crisp 4.5-pound break and fast lock time. A B5 Systems P23 grip and Bravo buttstock on a Mil-Spec tube complete the lower assembly.

The cold hammer-forged barrel has a 1:8" twist for stabilizing 35–77 grain bullets. It features M4 feed ramps, a matte black oxide finish, and a Ruger® radial-port muzzle brake for recoil mitigation. The mid-length gas system provides reliable and smooth cycling.

Includes: one 30-round Magpul® PMAG® magazine.
