I posted this on a muzzleloader forum but I know you guys will have some outside the box ideas…… I put a western precision peep on my TC encore for an elk trip this fall. Was shooting this morning & thought “hope that front housing & peep don’t get bumped in the scabbard on the ride in” only thought about it b/c the other guy I’m going with had his come off his cva twice & has since jB welded it on. Mine feels secure but it is kinda hanging out there. Looks like this , front housing about diameter of a penny. Would love to get something 3d printed but came up with a few other ideas like some pvc pipe that could snap onto the barrel & the have a ribber strap or elastic
