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.

Both the K-SPEC Carrier and K-SPEC Bolt are backwards compatible with all standard mil-spec BCG components.  The K-SPEC bolt can be used in any AR15 style direct impingement system, and the K-SPEC Carrier will function perfectly with any standard AR15 bolt.

Because we manufacture our BCG components in house and do not rely on outsourcing, KAK is able to offer the K-SPEC complete BCGs and components in over 50 combinations from 5.56 NATO all the way to .458 SOCOM, in multiple finishes, and left-hand versions as well.

? 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.

? 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. A quick side by side comparison video of a standard BCG and the K-SPEC BCG can be viewed HERE. *Note, standard BCG on top (lots of gas to face) and K-SPEC BCG on bottom (no gas to face).

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.

Conventional extended base pads primarily have a square or rectangular shape. Their designs mostly consist of flat or slightly angled surface areas on all sides and a flat section on the bottom. These designs are not ergonomic. They do not provide proper surface contact and feedback to the shooter during the reload sequence.

The advanced ergonomic design of the Grip Force EBP resolves all of these issues of conventional extended base pads.

The Grip Force EBP is the result of ergonomic evolution. When developing the Grip Force EBP, we studied the exact manner in how the human hand operates during a reload sequence. How the hand indexes the base pad and magazine in its pouch. How it wraps around the base pad and magazine body when removing the magazine. How it orients the magazine toward the magazine well, and how the hand functions when inserting, seating, and locking the magazine into the pistol.

The Grip Force EBP is designed to work with the hand naturally. The result is optimized speed and efficiency of the reload sequence.

FIT = FUNCTION

The EBP design allows for a faster and more consistent index.

The EBP fits the hand better, increasing feel and control.

The extended and contoured underside remains in contact with the hand during reloads. That continuous hand contact increases speed and efficiency.

The Grip Force EBP can be used on Standard (G17/G22) or Compact (G19/G23) sized magazines. The Grip Force EBP increases magazine capacity by +5 rounds of 9mm and +4 rounds of .40 cal.

Additional features include:

• Ambidextrous indented side panels enhance the operation for immediate action drills.

• A reinforced 3-pin locking bridge offers additional security against the base pad separating from the magazine body.

• The ergonomic shape of the EBP aids in concealed carry; the base pad design prints less underneath clothing.

• The ergonomic shape of the EBP offers an enhanced grip surface for compact (G19-sized) pistols.

• The EBP has a non-glare finish, suitable for MIL/LE duty use.
