Key Features
- Billet 7075 T6 Receivers — Why it matters: Aircraft-grade aluminum gives you a rigid, corrosion-resistant platform that holds zero and handles hard use without cracking.
- 16.1-inch MT 4140CM SBN Barrel — Why it matters: This chrome-moly steel barrel with a salt bath nitride finish resists fouling and heat, delivering consistent accuracy round after round.
- Magpul SGA Stock — Why it matters: The Remington-870-pattern stock provides a solid cheek weld and adjustable length of pull, letting you fit the rifle to your body and shooting style.
- Direct-Impringement Operating System — Why it matters: Proven, simple gas system with fewer moving parts than a piston — easier to maintain and lighter on the front end.
Who It’s For
This rifle is for ranchers and rural workers who need a reliable varmint and predator gun. The .22 ARC round gives you flat trajectories out past 400 yards with low recoil, making it ideal for coyotes, groundhogs, and other pests. If you want a lightweight AR that runs clean and hits hard at distance, this is your tool.
Pros & Cons
- Pros: Accurate 1:7 twist barrel, durable billet receivers, comfortable Magpul stock, Cerakote finish resists weather, low recoil.
- Cons: The direct-impingement system can run dirtier than a piston gun — expect to clean it more often if you shoot suppressed or in dusty conditions.
