Colt Ar15 M4 5.56 16 Enhanced Patrol Rifle

The Colt AR15 M4 5.56 Enhanced Patrol Rifle is a 16-inch modern sporting rifle built on Colt's legacy of reliability and built to meet the needs of shooters who want a dependable, versatile platform for duty, sport, or home defense. This rifle strips away unnecessary extras and focuses on what works: a proven direct impingement design in a compact, ergonomic package that's equally at home on the range, in competition, or standing ready.

The heart of this rifle is a 1:7 chrome-lined barrel with an A2 flash hider, a time-tested combination that delivers consistent performance across a wide range of 5.56 NATO ammunition. The chrome lining adds durability and corrosion resistance for shooters who demand longevity from their rifle. At 16.1 inches, the barrel length keeps overall handling tight without sacrificing sight radius or velocity in practical shooting scenarios.

Factory-installed Magpul MBUS Pro front and rear backup sights give you confidence that your optic is mounted on a rifle that ships sight-ready. The M-LOK handguard accepts a full ecosystem of tactical accessories, and the Black Bravo B5 stock provides a comfortable, adjustable platform for different shooters and gear configurations. The rifle ships with a 30-round magazine, ready to function out of the box.

This is a Shooter's Model rifle, meaning each gun is brand new but may exhibit minor cosmetic imperfections that occurred during manufacturing—blemishes so subtle they're nearly invisible except under close inspection. If flawless aesthetics matter more than the function and accuracy Colt is known for, that's worth knowing. For shooters who prioritize reliability and performance, these cosmetic variations represent genuine value.
