Sentinel AR-15 Rifle

Crammed with components from top-tier tactical manufacturers, the Sentinel AR-15 rifle is proof that a badass, overbuilt AR-15 carbine doesn’t have to cost thousands of dollars. Whether it’s for duty or personal defense, the Sentinel is ready to meet the needs of tactical and defensive-minded shooters who are seeking a top quality AR-15 carbine at a price that won’t break the bank.

The Sentinel is chambered in 5.56 NATO, but you can also opt for the hard-hitting .300 AAC Blackout – a cartridge designed specifically to deliver higher muzzle energy from a comparatively shorter barrel. Subsonic 300 BLK also pairs well with a suppressor for ultra-quiet shooting.

Our Duty Series lineup was created with service members and first responders in mind, yet can easily double as a no-nonsense personal defense firearm. Featuring high quality, professional-grade parts, many with corrosion resistant finishes that also maintain lubricity to help ensure reliability at all times, these AR-15s will always have your back, even without a super-strict training or maintenance schedule.
