Introducing the Colt M.A.R.C.901 family of rifles. Each new rifle in the M.A.R.C.901 family is an evolution of the LE901-16S, which means the upper receiver group can be easily swapped out for any Colt upper receiver chambered in .223 Rem (5.56 x45 NATO) with the conversion kit (sold separately). Bolt and magazine controls are ambidextrous for flexibility and ease of use. Be it for whitetail hunting in Maine, target practice at the range or law-enforcement use, the Colt M.A.R.C.901 family of rifles have the power and versatility you need. Exceptional accuracy is assured by its full floated, 16.1” chrome lined barrel, and users can now find their perfect balance with customized mounting of accessories such as optics, bipods, lasers and more.
