Hey all I stumbled onto a buffer tube adapter for the PP750 at airgunarcheryfun. I got it installed this weekend and personally Im very happy I got it. The adapter puts a whole new feel to this gun. I had a sb tactical side folding adapter that I put in the mix. I personally thought the original stock was way too flexible for my taste even after I installed a 3d printed check riser on it. I'm looking forward to getting it out and doing some shooting. Here's a couple pics.
