Hello B26 Experts,
I am really loving my MM-B26 and recently bought a custom muzzle break from Rich that is about 5.5" long. I called Mike to ask his opinion about the proper placement of a muzzle break on this air rifle. His comment was to install it at first with a 1" gap between the bottom of the muzzle break and end of the barrel and take some shots to witness the precision. He also said that this dimension is a starting place and to play around with the distances until you get the best precision.
My question for you B26 users is what has been your best gap setting with a muzzle break. I would think its going to be between 1"-2". I plan to test this at the indoor range this week down the street when I get the time but it never hurts to ask others before I go on this endeavor.
