Evening all I have recently got a paul wilson stock for my ev 2. Stunning stock but the only problem is my mec postion butt hook fit so after selling that i am looking for the right but hook with the back late that fits flush with the stock. I have mearused the back of the stock and it is 135mm by 35mm and is rounded both top and bottom. look at the anschutz on blackpool air rifle but the plate is not rounded at the bottom. is there another type of back plat or does anyone know what but hook is that size. Any help would be great thanks
