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.

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.
