BLING BCG- K-SPEC, 5.56 NATO, Down Vent, Dual Ejector, TiN & Hard Chrome

Titanium Nitride Satin Finish

These came out absolutely incredible! Thanks to our supporters response to our April fools "Golden BCG" posts we just had to do a run.

First and foremost, the TiN finish on extractor is one of the only exceptions to the normal phosphate finish

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.

Reduced Peak DB Report

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

Downward Gas Vents

In an effort to reduce the amount of debris and gas vented towards the shooters face, the two standard gas relief ports have been relocated from the ejection port side of the K-SPEC carrier and placed underneath, in the magazine feed lip channels.  Two additional emergency relief ports have also been added to the bottom of the carrier to mitigate structural damage in the event of a case head separation.  Testing has shown that venting the gasses through the magazine well has no negative impact on the feeding or function of the magazine nor ammunition, and any added heat is negligible. 

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

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.
