KAK Industry K-SPEC Enhanced AR-15 Bolt 5.56/300 BLK

KAK Industry's K-SPEC bolt runs two ejectors instead of one. Both are mil spec parts, so nothing proprietary is needed to service it, and the ejector holes sit centered on the lugs so the bolt gives up no strength to get the second ejector. The payoff is a tighter, more consistent ejection pattern instead of brass landing anywhere it likes.

This is the assembled bolt only, machined from steel with a phosphate finish, and it works with any standard mil spec carrier group. The bolt face covers 5.56 NATO and 300 BLK, which share the same case head, so one bolt handles both uppers.
