Rock solid adapter - Vltor RE47 AK47 Receiver Extension Modstock Adapter Aluminum Black

The Vltor buffer tube adapter is an exceptionally made piece that's great for upgrading your AK. The kydex inserts fit a variety of receivers thanks to their interchangeability. I was able to fit and mount it on my PSA GF3 within 5 minutes tops, making it my go to for a modernized AK build. It also pairs exceptionally well with any Vltor brand stock, especially their IMOD line up as there is little to no play in the stock and fits very snug to the tube. Only major downside is that it will add some extra weight overall to your AK.
