About the Mesa Tactical Adaptor:

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™ (They are an extra $100 if you wanted to add one to your kit)  that reduces felt recoil. The Mesa Tactical Adaptor is by far the most robust and most effective of several shotgun stock systems on the market.
