The TBL-37* is a tactical launcher chambered in 37mm and made to the highest standards of American workmanship. Constructed of 6061 aircraft grade aluminum and 4140 hardened steel, it is rugged while maintaining a reasonable weight. The standard finish is matte black.
The first version of the TBL-37 was known as the Fireball. Under that name it was extensively tested by George ("Grog") Confer of L5 Productions and noted authority on 37mm and 40mm ordnance. Grog’s early review helped us to refine several important aspects of that model. Further modifications resulted in a sleeker, more tactically oriented, design that was different enough to warrant our renaming it the TBL-37.
Based on the proven design of the Viet Nam era M-79 grenade launcher, the TBL-37 has advanced it to new levels. Replacing the heavy wooden stocks with modern tactical black poly was the beginning. We added a full barrel length Picatinny rail on the top and a short rail under the muzzle. These allow the owner to interchange tactical accessories thus providing the ultimate in flexibility. We have also replaced the old flip up sight with a state of the art laser red/green dot sight as standard equipment. This can, of course, be interchanged with any other sight or scope that mounts on a Picatinny Rail.
While we use strong 6061 aircraft grade aluminum for the barrel and receiver, where additional strength is required 4140 hardened steel is employed. These areas include the trigger, hammer, barrel pivot, and recoil plate. This strikes the correct balance between manageable weight and safety.
