Redesigned 40mm UBGL from Fabrykę Broni

    The Polish firearms company Fabrykę Broni has brought their redesigned 40x46mm Low Velocity Under Barrel Grenade Launcher to the public. The company had a previous 40mm UBGL that incorporated a slanted grip with the trigger almost underneath the muzzle of the grenade launcher (this looks like it allows a significant reduction in weight). With this redesign, the company has placed the trigger inline with the barrel, directly in front of the magazine, very similar to Russian GP30 grenade launchers. It appears that the grenade launcher does not require a proprietary handguard to be mounted to the 5.56x45mm MSBS rifle (example shown with 7.62x39mm MSBS).

    Similar to the previous launcher, the tube is opened to the left, allowing the use of longer 40mm grenades to be chambered, in addition to standard ones. The safety is on the right side, and the barrel latch on the left, facilitating a quick release. Sights are on a picatinny mounted rotating quadrant rail on the left side, mounted to the handguard of the MSBS. Theoretically this should allow the same sights to be mounted on the right side for left handed users, but I couldn’t find anything that confirms this. The entire package appears to be a very compact design, is probably one of the shorter of all the current issue 40x46mm grenade launchers on the international market.
