K-SPEC Enhanced AR15 Bolt- 5.56/ 300 Blackout, Dual Ejector, Full Chrome, C158
The K-SPEC dual ejector system uses mil-spec ejectors and springs that require no proprietary parts. Ejector holes are centered on the lugs to avoid any reduction in strength of the bolt. The dual ejector system increases the ejection reliability and adds consistency to the ejection pattern. KAK Industry has been manufacturing dual ejector bolts for the AR10/LR308 platform for over a decade and has used that experience to create a durable and reliable dual ejector system for the AR15 platform.
The K-SPEC Bolt is backwards compatible with all standard mil-spec BCG components. The K-SPEC bolt can be used in any AR15 style direct impingement system.
