Colt's LE6920MPS shares many features of its combat-proven brother, the Colt M4. The heart of this carbine is its 16.1" chrome-lined barrel. With a 1:7" twist, ammunition selection is virtually unlimited. Colt teamed up with Magpul Industries to outfit this carbine with the most highly sought-after accessories. The Magpul MOE SL buttstock, handguard, and pistol grip feature a narrow Slim Line design with an anti-snag dual-side release latch on the buttstock. The handguard has slots at the two, six and ten o'clock positions for mounting direct-attach M-LOK accessories.
