About the AIM Tactical Adaptor:

-Zytel Construction

-Lifetime warranty


The most important capability of these adapters is to facilitate the use of collapsing or telescoping stocks, which provide a shorter length of pull (LoP) than the factory stock, which is especially important for law enforcement or “tactical” operators. In addition, these stock adapters accept a hydraulic buffer from Crosshair™ that reduces felt recoil. The AIM is by far the most effective of several shotgun stock systems on the market.
