KAK Industry K-SPEC AR15 Bolt Carrier Group 5.56 Satin Gold
KAK Industry K-SPEC AR15 Bolt Carrier Group 5.56 Satin Gold
The KAK Industry K-SPEC AR15 Bolt Carrier Group is a low mass BCG for 5.56/.223 rifles, built around a satin gold anodized aluminum carrier and a 9310 dual ejector bolt with an NP3-coated cam pin. Its reduced reciprocating weight suits mid-length, rifle-length, and similar gas systems, and the down vent design supports consistent cycling in a properly tuned AR.
Because it is a consumable part, the K-SPEC performs best with matched gas and buffer tuning and is not intended for hard use applications.
