BM M4A2
The Bushmaster M4A2 Carbine was first introduced in the early 1990s as a compact and lightweight version of the standard M16 rifle. It was designed for use by special forces, law enforcement, and other military personnel who required a more maneuverable weapon for close-quarters combat.
Bushmaster M4A2 Carbine, caliber 5.56x45mm NATO. I am one of the current M4 variants being produced. Although smaller to full-size rifles like the M16 family of rifles, we carbines still share the same platform, the AR-15 platform.
