2015 Colt LE6920 "M4 carbine" and "Colt Defense" marked. 16.1 chrome lined barrel with 1/7 twist.

Has around 3 mags (90 rounds) thru it with zero issues. Never dropped, stored in case, etc. Nice and tight firearm.

2 p-mags included (Black and Tan). Believe the rear sight installed is off my S&W M&P 15/22 as this firearm came with no rear sight. I intended to upgrade, but never did.

Nice Colt AR-15 firearm with all the right stampings, with very minimal use.
