This Bravo3d Adaptor allows you to attach a Picatinny folding stock.
Huben Gk1 can now be fitted with a picatinny folding stock. Making it the best hunting pellet gun rifle. I like to use it for pest control at night for the rats. Because it is semi auto and I get a quick follow up shot. Also with the bravo3d stock it becomes the best high powered air rifle for hunting. If you want to turn your Pistol into a Carbine this is the kit for you.
