Colt’s LE6920 Semiautomatic Tactical Rifle is a AR-15 series firearm that features an M4 chrome-lined barrel that has a 1:7 rate of twist making your ammo choices virtually unlimited. Muzzle compensator lessens muzzle rise keeping you accurate during rapid fire. Direct-gas-system action with locking bolt reliably and quickly feeds shells. Magpul MBUS® flip-up rear sight adjusts for windage 4 position adjustable stock and 30-round Magpul PMAG® magazine. Colt’s LE6920 starts with a high-strength polymer four-position collapsible stock on the lower receiver assembly and a standard semi-automatic AR-15 trigger assembly inside. If you prefer a specific brand of custom trigger no problem. The LE6920’s lower will accept any standard AR trigger assembly—that’s the beauty of a standard impingement AR-15/M4 with mil-spec parts and rails. You can throw any furniture your heart desires and wallet can support on or in it. Something not seen on many of the ARs being produced today can be found under the M4 hand guards on the LE6920—double heat shields. That does not seem significant on the showroom floor but it will after you burn through a couple of mags in quick succession. The muzzle compensator reduces muzzle climb and helps eliminate flash and dust signatures. – Specifications and Features: – Action: Semi Auto – Caliber: 223 Rem/5.56 NATO – Capacity: 30+1 – Finish: Anodized – Twist: 1:7 – Overall Length: 32-35 – Front Sight: Adjustable – Rear Sight: Flip-Up – Barrel Length: 16 – Stock: Adjustable – Color: Black – Length: 35.5 – Weight: 6.95 lbs. – Barrel: M4 Chrome-lined
