Thanx Guys; I think I'll go with it. During my first trip to the range as the newest member of our black powder group, I became aware that with the range busy, flash from flint guns was something to be managed. I mainly wanted to be sure the guards weren't known for deflecting the jet directly at your powder flask or somewhere else that might be of concern. I know from other shooting disciplines that some add ons are a good idea, others are not. Thanx again !
