The trigger guard on BBR is slightly wider than trigger guards of TBR and the stock may not be inleted wide enough to accommodate it.
On a few projects I have going I'm using BBR actions with TBR stocks and just keep the regular trigger guard on it. If I'm needing to remove the bolt I'll take off the trigger guard and use the Allen key to move the lever back once its exposed. Its about the same amount of trouble as the BBR is the way its designed.
