The KAK 5.5 oz buffer is specifically weighted to handle the unique cycling requirements of 9mm blowback operation, while the 6-position adjustable stock allows shooters to customize fit and comfort. Included end plate and spring complete the installation hardware needed for a functional buffer system.

SOPMOD Style Stock with Integrated Storage

The SOPMOD style collapsible stock offers more than just adjustability—built-in storage compartments provide convenient space for batteries, spare parts, or cleaning accessories. Six positions of adjustment accommodate different shooter sizes and shooting positions or allow for changes based on gear configuration. Nylon reinforced polymer construction delivers durability without excessive weight.

KAK 9mm Buffer for Reliable Cycling

The KAK 5.5 oz carbine buffer is engineered specifically for AR-9 platforms operating with 9mm (9×19) cartridges. This heavier buffer weight is optimized for the blowback operation characteristics of pistol-caliber carbines, supporting smooth cycling and managing the bolt's reciprocating mass effectively. Paired with the included carbine recoil spring, this combination delivers reliable function in 9mm AR builds.

Durable Installation Hardware

The US Tactical Mil-Spec receiver end plate features a phosphate finish for corrosion resistance and secure buffer tube installation. Combined with the spring steel carbine recoil spring, these components ensure your buffer system remains properly positioned and functional through extended use.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify buffer weight and spring rate compatibility with your specific barrel length and build configuration. This bundle is designed for 9mm (9×19) AR-9 platforms—ensure compatibility with your receiver and bolt system.
