General Info: Lower Parts Kits include all of the small bits & pieces needed to make your AR-15 Lower fully functional. Such as the mag release, take-down pins, selector, trigger guard, bolt catch, buffer retainer, roll-pins, detents, and small springs are included to allow completion. 'Mil-Spec' fire control group kits include stronger springs meant to ignite hardened primers found on M855 (Green Tip), XM193, and other military 5.56x45mm loads.

Brand: The Mil-Spec Lower Parts Kit is produced by KAK Industry with high-quality steel & brass components.

Brand Info: KAK Industry was founded and incorporated in 2011 by Kurt Kosman to address a gap in the firearms market for quality, American-Made components at affordable, sustainable prices. KAK began in one small shop, supplying specialty firearms components with innovative designs to shooters and hunters across America. Almost immediately, the demand for these products grew to such that a dedicated manufacturing facility was opened in Southern California, a major aerospace manufacturing hub.

Platform: Mil-Spec AR-15

FCG Included: The Mil-Spec KAK kit comes with a Mil-Spec Fire Control Group to ensure reliable operation and ignition of hardened rifle primers.

Grip: The Mil-Spec lower parts kit includes an A2 style grip and grip screw to complete your AR-15 lower receiver.
