Zenith Zf-56 5.56 NATO Rifle, 14.5" Barrel, 30-Round Capacity$1,536.25
Availability: In Stock
The Colt M5 Sentry rifle in 5.56 NATO is a modern semi-automatic carbine built on Colt's redesigned receiver platform, engineered for shooters who demand both precision and everyday practicality. With a 16-inch barrel, ambidextrous controls, and a rigid free-float rail system, this 5.56 rifle handles equally well on the range, in the field, or as a reliable defensive tool. At 6.8 pounds unloaded and configurable between 32.5 and 36 inches in overall length, the M5 strikes a balance between maneuverability and shootability without sacrificing durability or ergonomics.
The receiver set is machined from 7075-T6 aluminum and finished in black hardcoat anodize, a combination that resists corrosion and handles hard use. The 4150 chrome-lined barrel features a 1:7 right-hand twist optimized for a wide range of 5.56 loads, and the direct gas impingement system is proven, familiar, and easy to maintain. Colt's carbine-length gas tube keeps the action smooth without excessive bolt carrier speed, and the free-float design minimizes contact between barrel and handguard for consistent accuracy.
Controls are truly ambidextrous—safety lever, magazine release, and charging handle all work from either side—making this rifle accessible whether you're right- or left-handed. The single-stage trigger, government-profile grip, and folding low-profile front and rear sights give you a solid base to work from out of the box. The 30-round Magpul PMAG and cable lock are included, along with the owner's manual.
