The K-SPEC BCG combines multiple key features focused on increasing the reliability of your AR15 style firearm no matter if you are running suppressed or unsuppressed, and regardless of conditions.  The K-SPEC is a truly plug and play BCG that will accommodate whatever configuration your mission requires.

For those running suppressed, the K-SPEC requires no additional tuning or tweaking of the gas or recoil systems to run reliably.  Like all KAK BCGs, the K-SPEC is machined to the M16 full auto profile.

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 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. 

NP3 coating is a specialized type of coating often used in firearms and other high-wear applications to enhance durability and reduce friction. It's known for its ability to offer excellent resistance to wear, corrosion, and fouling. The NP3 coating is a proprietary finish.

The coating is applied through an electroless nickel plating process combined with a fluoropolymer, which gives it its unique properties. The fluoropolymer component helps to reduce friction, which can improve the performance and longevity of the coated parts. This makes NP3 particularly popular for use in firearms, where its low friction and resistance to corrosion and fouling are highly valued.

If you have any specific questions about NP3 coating or need details on how it's applied or its benefits in a particular context, feel free to ask!
