KAK Industry A2 Buttstock Kit Features The KAK Industry A2 Buttstock Kit bundles all six components needed to install a complete A2 fixed stock system on an AR-15 or M16 pattern rifle. Included are the AR-15 rifle spring buffer A2 extension tube A2 spacer and assembly screw so there is no need to source individual parts separately. The polymer A2 stock itself measures 10.5 inches and carries a matte black finish that matches most factory AR-15 furniture. Because every part arrives together installation is straightforward for armorers and home builders alike. Beyond the fixed reliable platform an A2 stock provides the polymer stock body includes an internal storage compartment for holding small spare parts a cleaning kit or a spare battery. KAK Industry built this kit as an affordable way to replace a damaged or missing A2 stock without hunting down discontinued factory parts. Weighing in at roughly two pounds the kit is a simple bolt-on solution for restoring an AR-15 to proper fixed-stock configuration. KAK Industry has built its reputation on American-made AR-15 components sold at accessible prices and this kit reflects that same value-driven approach.
