5KU SPORT4 & B33 Tactical Handguard and Picatinny Dustcover Kit for MARUI AKM GBB

A full tactical overhaul for Tokyo Marui's Gas Blowback AKM, replicating the renowned Zenit-series of external parts. 

SPORT4 Handguard

A recent development in the now-iconic lineage of Zenit's aggressive handguards, the SPORT4's silhouette is narrower and shorter than previous designs, shrinking the overall profile of an AK's front end as much as physically possible. Now, users can enjoy an improved grip from a smaller, relaxed grasp of the handguard. 

Consisting of an upper and lower half, fixing onto each other whilst held in place via the AK's front retainer. Up top are two short length of picatinny rail for mounting lasers, torches and pressure pads. Down below are three full-length sections of Zenit's 'Basis' attachment system, compatible with B-2 rail sections - sold separately. 

B33 Dust Cover

One of the fundamental flaws of the AK platform is that the dustcover will not hold zero due to its loose attachment - a problem that carries over to GBBR AK's with their notoriously strong kick. The B33 solves this problem by fixing itself onto any Zenit-style handguard via four fixing points, on top of the traditional push-button latch at the rear of the receiver. Now with vastly increased rigidity and elimination of wobble, mounted optics will not lose zero.
