[QUOTE="J E Custom, post: 246900, member: 2736"] Lapping the recoil lugs increases the contact to 100% between the bolt and the recever. this helps prevent the bolt from moving when fired and distributes the loading of the bolt and recever equally improving accuracy. It also smoothes the surface so the bolt will ingauge and dis-ingauge easer. But I don't recomend lapping unless you can lapp before final head space or you will increase head space to an unexceptable amount. If the head space "Is" tight then lapping will loosen it . Jeweling the bolt helps hold oil/lubricants on moving parts and also makes it look better. J E CUSTOM [/QUOTE]
