[QUOTE="tobnpr, post: 2033830, member: 68758"] Tolerances are critical here. One needs to determine boltway clearance before Cerakote. It's going to reduce clearance [B]minimum [/B]two thousandths, and make that four thousandths if the receiver is done as well. A decent-fitting bolt isn't going to have much more than that to begin with... On precision bolts with two thou or less clearance, I'll relieve the center of the bolt by about five thousandths. This makes for easier running, shed foreign matter/debris easier- while still locking up tight and precise at the ends when in battery. Cerakote Micro-Slick is a good product to reduce friction on bolts (you'd need to blast your bolt clean first): [URL unfurl="true"]https://www.cerakote.com/shop/cerakote-coating/C-110/micro-slick-dry-film-lubricant-coating-air-cure[/URL] [/QUOTE]
