Colt M.A.R.C. 901™ Modular AR Carbine


Colt’s Manufacturing Company evolved its highly popular LE901®-16S modular carbine design by introducing the new M.A.R.C. 901™ (modular AR carbine) product family. This family of modular and customizable carbines features four new models: LE901®-16SE, LE901®FDE-16SE, LE901®-18SE and AR901™-16S. All-new “SE” models in the M.A.R.C. 901 family feature a monolithic upper receiver with a fixed rail at the 12 o’clock position and provisions to mount rails at the 3, 6 and 9 o’clock positions. The AR901 features a flat-top upper receiver and a tubular forend, with provisions to mount rails at various positions. Three SE models, the LE901-16SE, LE901FDE-16SE and LE901-18SE, all also feature ambidextrous operating controls for the magazine release and bolt catch, and a single-side reversible fire selector. All three of these models are designed with a free-float barrel, VLTOR™ buttstock and locking folding sights. Unique to the LE901FDE-16SE is the flat dark earth finish on the upper and lower receiver, along with FDE furniture. For users who prefer a longer barrel, the LE901-18SE with its 18-inch barrel is the optimal choice. The LE901-16SE and LE901FDE-16SE models weigh 8.42 pounds and all models have a 1/12 RH twist. The fifth model in the M.A.R.C. 901 family, the AR901-16S, is the perfect balance between LE901 quality and affordability. It features a free-floated barrel and user-configurable tubular handguard with rail mounting provisions beyond the standard 3, 6, 9 and 12 o’clock positions to include rail mounting positions on 16 different planes. The AR901-16S has a B5 Bravo buttstock and measures 34.24 inches with the stock retracted, or 37.5 inches with the stock extended. It has a 1/12 RH twist and weighs 8.24 pounds.
