WBP Underfolder/Pistol Rear Trunnion
Wytwórnia Broni Jacek Popiński (WBP)
WBP Polish production black synthetic buttstock with sling loop. This light weight synthetic buttstock is nicknamed by AOA "the club" because it is a no nonsense, no frills, rock solid fiberglass reinforced stock designed to handle the tasks original buttstocks were designed for.
It obviously does not have a trap door cleaning kit slot since it is not hollow and you will have to drill the stock screws once you insert it into the trunnion and receiver. This is an excellent stock for the money and can't be beat strength wise.
This stock has notches cut to fit Beryl style trunnions such as those found on the WBP Fox.
