MAGPUL ACS Milspec Diameter Stock Kit in Olive Drab Green is a convenient "drop-in" replacement for an AR15/M16 buttstock. It features special mil-spec receiver extension tubes and an anti-sag profile that protects the release latch and prevents accidental activation.

The MAGPUL ACS Milspec Diameter Stock Kit comes with a chrome-silicon spring that prevents auto-collapse failure. You also get a friction-lock system designed to reduce the amount of wobble for higher accuracy and stability when in use.

The butt of the stock features multiple storage options plus areas for water-resistant battery storage.

The kit also comes with a rubber butt to reduce shoulder slippage when wearing modular gear or body armor.

The MAGPUL ACS is, therefore, the stock kit you've been looking for. Water-resistance, combined with helpful ergonomic features, make this the ultimate companion of your AR15/M16 in the outdoors.
