I appreciate both Gene and Shadows help,i have been hunting for 50 years,first 20 with firearms,the rest with bow,the springer was just taking up 10 years ago but not that much interest ,untill a friend of a friend said he was squirrel hunting with airgun,a shadow by gamo,well i thought that would be great to hunt squirrels were i bow hunt,i would never use a powder gun in my bow woods,after getting viper,i found a whole new way of hunting,lol.
My rest will be used for sight-in muzzleloader,but will mod.by making 2 new rice bag ,removable mounts for rest, so thanks for your advice,thats why i,m here,to learn. Paul
