These Law Enforcement Carbines were introduced in 2009 with the .154" small-pin firing-control-groups (FCG)'s as opposed to the .170" large-pin FCG's that have been used since the introduction of the Colt Blue Label Rifles in 1991. The .154" small-pin FCG's allocate the installation mil-spec FCG's and are NOT restricted to the Colt proprietary FCG's. Each Colt LE 6920 is marked "Restricted Military/Government Law Enforcement Use Only." Colt firearms have always held their value and they most accurately produced M4 type carbine available. Each Colt LE 6920 includes two twenty round magazines, cleaning kit, sling, and manual. If you have any questions, please do not hesitate to email me at. Each Colt LE 6920 is available for $1200. Thank you for your time, I look forward to doing business with you. SAMMY!
