Bushmaster's 16" Bbl. Modular Carbines combine many of the most popular items from the Bushmaster Modular Accessories System (B.M.A.S.) into a completely unique firearm. Designed around an A3 type "flat-top" upper, the modular carbine has a 16" chrome-lined, fluted barrel with milled gas block. A B.M.A.S. four rail free-floater forend, combined with the A3 type "flat-top" upper receiver provide all the picatinny rails necessary for sights, scopes or accessories. Molded rubber sure grips snap over the rail sections to add comfort and rail protection. The dual aperture B.M.A.S. rear flip-up sight is a detachable unit with a windage knob calibrated to 1/2 Minute of Adjustment. The B.M.A.S. front flip-up sight clamps around the milled gas block, and an ergonomically contoured pistol grip completes this special carbine.
