I bought this and a folding stock for my Huben GK1. For my use, the folding stock was better for me. Instead of returning this and screwing over the seller I'm just going to sell it at a discount and give somebody a good deal. From the website it's $119, I'm going to sell it for $90 including shipping. I put it on my gun and used it for one day still looks brand new.
Please note I included a picture of my gk1 with it installed so you can get an idea of what it looks like but the gun is not included lol.
