So I got my step-son a muzzleloader last year and the rear sight on it is busted. We want to switch it to a peep sight anyway because he shoots pretty good with peeps. It is a TC Thunderhawk and it has been impossible to find a peep for it. Contacted Williams and they dont have one that matches. I have been able to find the scope bases though, which would allow us to mount the NECG peep. By the time the peep and the bases are bought its roughly $120. I was curious if it would cost less if we have it drilled and tapped to have a peep for a newer model peep to go on it.
