Colt Mfg M5 Sentry Rifle 5.56 NATO 16" Barrel 30-Round Capacity CM556-16-M5S
Colt
The Colt CR6960 carbine is a no-nonsense 5.56 NATO rifle built for shooters who want proven ergonomics and reliability without unnecessary frills. This midlength gas system carbine sits at the sweet spot for most shooters: compact enough for tactical drills, training, or home defense, yet accurate and controllable enough for precision work out to distance. With a 16.1-inch barrel and overall length adjustable from 32 to 35.5 inches via the six-position telescoping stock, it handles tight spaces and shoulders comfortably whether you're running a course of fire or working from a vehicle. At 6.5 pounds unloaded, it's built to carry—not a featherweight, but not a boat anchor either.
Colt equipped this rifle with a flat-top receiver that accepts standard optic mounts, a Centurion Arms handguard with M-LOK compatibility for lights, lasers, and accessories, and a 1-in-7 right-hand twist barrel that stabilizes a wide range of 5.56 ammunition. The manual safety and bird-cage flash hider are time-tested controls and features. Magazines are not included—you'll need your own 30-round (or pinned) mags—but the CR6960 feeds standard AR-pattern magazines reliably.
This is a working rifle: not decked out in mall-ninja gear, not feature-bloated, just a solid platform for hunting, range time, defensive scenarios, or learning. The midlength gas tube runs cooler and softer than carbine-length setups, improving longevity and felt recoil. If you're in the market for a battle-tested AR-15 pattern rifle and want to skip the build-your-own complexity, the CR6960 delivers the performance Colt's earned over decades.

The CR6960 comes with one magazine. You'll need to source additional magazines separately; it accepts standard AR-15 pattern 30-round magazines.
The midlength gas system operates with lower pressure and softer recoil impulse than a carbine-length setup, which typically results in improved reliability, easier shooting, and longer component life.
Yes. The 5.56 NATO cartridge is legal for varmint and predator hunting in most states, and the rifle's accuracy and ergonomics make it well-suited for hunting applications where .223 or 5.56 is appropriate.
