The 2 lug wrench will fit the following BAT actions: S, SV, SB, B, DS, MB, M, CT, L, HR, VR, & TR.

The 3 lug wrench will fit the BAT model 3L and 3LL.

The BAT rear entry wrenches are made to slide into the rear of the action until it touches the barrel; this puts the twisting force in the strongest area of the action. These wrenches are made from stainless steel and are cut so a torque wrench can be used if desired.
