K-SPEC 224 Valkyrie / 6.8 SPC Enhanced AR15 BCG- Down vent, Dual Ejectors, Sand Cuts, Nitride

Patent Pending

224 Valkyrie 6.8 SPC and similar 

For enhanced functionality in adverse and rugged conditions such as sand, mud, dirt, and grime. These rail cuts are designed for debris disbursement, resulting in ultra-high functionality in the toughest conditions, including suppressor fouling and foreign contaminates. Strategically located angle cuts in the rails result in fouling and debris being moved into noncritical areas that are not in contact with the receiver and do not affect the function of the firearm. aka sandcutter

Reduced Peak DB Report

When used in conjunction with a silencer, the gas redirect produces a quieter report

Dual ejectors

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.
