Professional bar adapters from Mike Manley. These bar adapters allow you to run 12mm Stihl mount chainsaw bars on the Dolmar/Makita 6300-7910 chainsaws. This is great for those operators who run both brands of saws, because you only need one type of bar now, one with a 12mm Stihl mount. Please check your saw before ordering. Important Note: Not all bar mounts are manufactured the same. Some bars may require adjuster holes to be slightly enlarged for bar adjuster tab to fit.
