This titanium bolt handle is 1/2" longer than the factory handle. It is much easier to operate without a change of head position. Makes any rifle cycle faster, feed better, and be generally easier to get along with. This assembly, along with the Titanium Firing Pin (product #428267 - not inlcuded) make a lighter, smoother, more positive feeling action for faster cycling and more positive ignition. Does not fit Ruger 10/22 Magnum.
