The latest M4 V3 Gas Blowback (GBB) system from GHK features a remarkable configuration inspired by the MK12 MOD1. Officially licensed by Colt through Cybergun, this airsoft replica bears authentic Colt M4A1 Carbine markings, engraved onto a robust receiver finished with a Cerakote coating. The front end is equipped with an MK12 MOD1-style handguard (MIL-STD-1913) and an impressive 18-inch steel outer barrel, complemented by a steel muzzle brake and collar—true to the "12th Model" design.
Internally, the completely redesigned V3 bolt carrier group (BCG) delivers significant performance enhancements. A new nozzle increases cylinder capacity by approximately 20%, resulting in improved gas efficiency and a firmer, more responsive recoil. Ballistics have also been optimized through an advanced BB-loading stop mechanism. To ensure smooth operation, the rear of the bolt carrier group incorporates a specialized correction surface.
