Freefloat Precision and M-Lok Modularity

The ACE-20 Series 7-inch freefloat handguard isolates the barrel from any contact, delivering consistent accuracy shot to shot. M-Lok slots along the entire length let you attach lights, grips, rail systems, and other accessories exactly where you need them without adding permanent modifications.

Compact Barrel and Pistol-Length Gas System

The 7.5-inch barrel paired with pistol-length gas tuning creates a fast-cycling platform optimized for close-quarters performance. The 1:7 twist rate stabilizes 5.56 NATO ammunition across the full spectrum of bullet weights, from lightweight varmint rounds to heavier tactical loads. The micro low-profile gas block keeps the top rail clear for optics and iron sights.

Magpul BTR Brace and Buffer System

The Magpul BTR Brace delivers a secure, comfortable wrist support platform that mounts to a standard mil-spec buffer tube. The heavy-duty buffer tube is rated for extended shooting sessions and accommodates standard AR-15 buffer and spring components. The brace design allows for rapid transitions and provides a stable platform for both one-handed and two-handed shooting.

Complete Bolt Carrier Group and Charging Handle

The 9310 alloy steel bolt carrier group features a nitride finish for corrosion resistance and durability. The mil-spec charging handle provides reliable bolt manipulation without snagging or binding, even under rapid fire conditions.
