Key Features
- Forged 7075 T-6 Aluminum Receivers — Mil-spec strength and dimensional consistency ensure tight lockup and long service life under sustained firing schedules.
- Free-Float M-LOK Handguard — Eliminates barrel contact for improved accuracy potential and provides continuous attachment points for lights, grips, and lasers without adding bulk.
- Mid-Length Gas System — Reduces felt recoil and carrier velocity compared to carbine-length systems, enhancing reliability and shooter control during rapid strings.
- Magpul CTR Stock and MOE Grip — Rugged, ergonomic furniture with a friction-lock buffer tube and a textured grip surface for positive control in wet or gloved conditions.
- Tiger Stripe Cerakote Finish — Applied over the receivers and handguard for corrosion resistance and a low-visibility pattern that breaks up the rifle’s outline in field environments.
