"The Close Quarters Battle Receiver has been more or less taken on by the Naval Surface Warfare Center, Crane Division (often referred to as NSWC-Crane or just "Crane") as its own project following the CQBR's removal from the SOPMOD program. Just as the Special Purpose Receiver morphed into the Special Purpose Rifle, and was type-classified as Mk 12 Mod 0/1, the complete CQBR-equipped carbine has been type-classified as the Mk 18 Mod 0."
Basically I choose to call it a CQBR because it's the correct term for the time period it is imitating. Also because Airsofters tend to throw Mk18 to anything with a resemblance to a SBR.
^Pretty much sums up my sudden switch. Still trying to get rid of my Aor1 sets, but when I'm done, my only stuff'll be an AK74u, a Glock 19, and a chest rig. In the future, maybe an M4. Nice blasters, btw!
