Colt AR-901 Complete Specs and Full Gun Specifications

Modularity in firearms design—the ability to exchange and combine system components and accessories—has increased greatly and is becoming more necessary. Mission and shooting requirements change, so it is useful to have systems that can easily adapt as needed. In keeping with this progress, Colt recently introduced its M.A.R.C. (Modular AR Carbine) 901 line. And it is truly modular. While Picatinny rails, for example, make it easy to swap out accessories, Colt has expanded upon this concept by adding configurable handguards (the rails themselves can be moved or removed).
