COLT M4 CARBINE MGPL 5.56 16.1

The Colt M4 Magpul Sentry takes the proven M4 platform and gives it a modern edge without losing what made it legendary. Built by Colt, this rifle keeps the time-tested M4 foundation while upgrading ergonomics with factory-installed Magpul furniture—no swapping parts, no guesswork.

You get a mil-spec lower, standard 6-position buffer system, and Colt’s high-quality 16.1" barrel with a 1:7 twist, topped off with a classic A2 flash hider. The Magpul handguard and foregrip add comfort and control, while the Magpul stock lets you dial in length of pull fast. It’s everything you expect from Colt—just more comfortable and ready to run.

If you want a dependable, duty-grade AR that updates a classic design without reinventing it, the M4 Magpul Sentry delivers.
