Hephaestus Recoil Power Kit for PTS / KWA Masada GBBR

KWA's Masada GBBR has already got a bit of a kick to it but definitely not as much as the real steel version, that much is a given. This Recoil Power Kit will add more recoil to every burst and is a definitely must-have if you want your Masada to feel like its real steel counterpart. You have to take into account that each kick will require more gas but it shouldn't effect the FPS at all.
