Just installed my new Boyd's Bmag Tacticool stock and I'm not impressed. The barrel isn't centered in the channel and the rotary magazine doesn't lock into place. Plus the contours don't work with the after market bolt handle I installed. Your trigger finger is almost pinched under the bolt handle when your finger is on the trigger in the firing position. I'll see what I can do with it. It's disappointing though. I've had two other Tacticools on my 22mag and 17hmr and they both fit perfectly.
