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. Compact carbine with semi auto allows for a quick follow up shot. Also with the bravo3d stock it becomes the best high powered carbine air rifle. If you want to turn your Pistol into a Carbine this is the kit for you.
I like the look of the pistol grip. It fits very well. Looks good at a reasonable price. I recommend using a lightweight aluminum or polymer side folder.
