KAK Industry K-SPEC Enhanced AR-15 6.5mm Grendel Bolt Carrier Group Side Vent Sand Cuts Phosphate Black. 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. Specifications for KAK Industry K-SPEC Enhanced AR-15 6.5mm Grendel Bolt Carrier Group: Manufacturer: KAK Industry Color: Black Finish: Phosphate Carrier Material: 8620 Steel Bolt Material: 9310 Steel Caliber: 6.5mm Grendel Gun Make: AR Platform Gun Model: AR-15 Hand: Right Weight: 11.5 oz Condition: New Cam Pin Material: 4140 Steel Features of KAK Industry K-SPEC Enhanced AR-15 6.5mm Grendel Bolt Carrier Group: Reduced Peak DB Report When used in conjunction with a silencer the gas redirect produces a quieter report 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 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. 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. AS 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.
