K-SPEC Enhanced AR15 BCG- 5.56/ 300 Blk- Dual Ejectors, Side Vent, Sand Cuts, Chrome Lined Phosphate, C158 Bolt

C158 Bolt

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

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.

Machined in house and assembled using only the finest steels and components. 

KAK Industry takes pride in producing some of the finest Mil-Spec/ Enhanced AR15 bolt carrier groups available, made 100% in house at our MO facility using Doosan machining centers, Tsugami Swiss turning, and the latest in FANUC robotics combined into an automated cell giving us lights out production capability.  In house automated CMM Inspection processes ensure consistent quality. 

Phosphate coating and chrome lining—provides a BCG with excellent protection against wear and corrosion, making it a popular choice for those seeking reliability and longevity in their firearms. The phosphate coating provides an initial layer of protection, while the chrome lining offers additional durability and resistance to the stresses of repeated firing.
