A commercial variant of the CM901 rifle, the LE901 was released to market in 2012.

Folding post front sight and rail mounted folding peep rear sight, and a Vortex flash hider and bayonet lug on the 1/12 twist barrel, quad-rail monolithic upper receiver and a UTG brand 3-9x32 scope. The lower is Colt Defense marked on the magazine well, with a right handed two-position safety and ambidextrous bolt and magazine catches. Fitted with a standard pistol grip, a Vltor 4-position telescoping buttstock. Four Magpul Pmag-25 magazines are included, as are three rubber rail protectors.
