These are high quality handles made of high tensile steel.AUTHORIZED DELTAC RESELLER NOTE: The Russian arsenal sometimes counter-bore the barrels to prolong their life by cutting out the bad/worn rifling at the muzzle end. If done properly a counter-bore has the potential to improve accuracy. The length of the counter-bore depended on how worn the muzzle end was. You should measure the depth of the counter-bore to make sure that this tool is long enough to reach the caliber bore of the rifle.
