If you’re looking for an extra 8 inches of reach on your shots, the Balabushka Cues Rear Extension is the perfect product for you! Simply replace your existing bumper with the one provided, and you can remove/add the extension as needed. Works exclusively with Balabushka cues that have a bumper that unscrews. If your bumper has a metal screw holding it in place, this adapter is not compatible with your cue– so make sure to check that yours is compatible before purchasing!
