Manny Sub single roller muzzle with ceramic bearings and inverted roller wheels. Kit includes adapter for 25.5, 26, or 26.5mm barrel inner diameters, Riley pulleys, stainless steel shackles, spliced 2mm dyneema, 18mm reactive, and 16mm progressive rubbers cut to length. I can tie the bands for an additional $50. I will need to know the barrel length and shaft diameter to accurately prepare the kit. I can also make up a different color muzzle at your request. 18mm reactive rubber comes in either red over amber or olive green pearl. I have 2mm dyneema for rigging in green, blue, or black. There is no instruction manual for this kit, so be sure you are comfortable with all the required rigging.
