Locking nut included in sale.

You can use any type of ammunition. Shoot the bird shot, buck shot and a slug of any mass and weight. If your gun can handle this ammunition, then GK03+ will defiantly withstand this ammo.

Created by CG in collaboration with Vsevolod Ilyin and made under his control. Unlike non-original analogs, it fully realizes the developer's ideas embedded in the product and, due to compliance with the technology, is durable and safe to use.

Differences of GK03+ from GK01 and GK02 in the next generation two chambers design, and not three as in the first three generations. This gave it a lot of positive effects: Muzzle Brake began to work more efficiently in rapid shooting mode. Maneuverability of the shotgun will greatly benefit from decreased weight of the muzzle brake and length of the weapon, both positively affects the manipulation of firearm.
