KAK Industry K-SPEC Side Venting 5.56 BCG with Dual Ejector Bolt
The K-SPEC Enhanced AR15 BCG is a high-quality bolt carrier group designed for use with 5.56, 300 Blackout, and 350 Legend rifles. It features dual ejectors for reliable ejection of spent casings and a sand cut carrier to increase reliability in harsh conditions. The slotted carrier rails provide smooth and consistent operation. This BCG is built to withstand the rigors of extended use and deliver consistent performance.
Slotted Angled Carrier Rails
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 sand cutter
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.
KAK Industry takes pride in producing some of the finest Mil-Spec/ Enhanced AR15 bolt carrier groups available, made 100% in house at their 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.
