Combat-Proven DNA Upgraded with Premium Magpul MOE SL Furniture

At the heart of the Colt LE6920 Slim Magpul rifle is its 16.1-inch chrome-lined barrel. Forged from 4150 Chrome Moly Vanadium (CMV) steel and finished with a durable manganese phosphate coating, this barrel is engineered for extreme longevity under harsh firing schedules. The versatile 1:7” right-hand twist rate optimizes stabilization for a vast range of ammunition weights, from standard 55-grain plinking rounds to heavy-duty 77-grain match and defensive loads.

To maximize ergonomics right out of the box, Colt collaborated with Magpul Industries to outfit this tactical rifle with highly sought-after Magpul MOE SL (Slim Line) accessories. These upgraded components improve weapon control, reduce bulk, and provide a seamless, modern profile.
