Our Fierce action requires Fierce bases. The screw holes to our base are the larger 8-40 screw size. This gives your scope attachment platform more strength to withstand the pressure from the heavier LR scopes that are very popular today.
There are two companies making bases for us right now. Talley and Murphy Precision. Talley makes a one-piece base and a 20 MOA rail. We also offer a 0 MOA rail at an affordable price. You can go to our store and BUY THEM NOW.
