Mesa Tactical High Tube Stock Adapter with 9.5" Rail for Remington 870 12ga #90630

Mesa Tactical

  • $28995

Note: This listing is for the high-tube adapter and 9.5 inch rail. Pistol grip, buffer tube and buttstock in the photos are not included.

Mesa Tactical’s Telescoping Stock Conversion Kit replaces the standard buttstock with an adapter that accepts AR-15 style collapsible stocks and pistol grips. High tube conversion kits have a stock height that is designed for AR height, rail mounted optic systems.

The stock adapters are investment cast aircraft grade aluminum, CNC machined and powdercoated black with a tough, chemical resistant finish.

The concept is simple: the shotgun stock is replaced by an adaptor that mimics the stock attachment point of an AR-15 lower receiver. This adaptor accepts an AR-15 receiver buffer tube (not included). The AR-15 collapsible stock and pistol grip (not included) can then be reliably attached to the shotgun. 

This kit comes with a 9.5 inch picatinny rail which screws into the top of the high tube adaptor and the screw holes in the top of the receiver. 

All High Tube adaptors accept push-button sling swivels. Note: Blanking plates to cover holes (see pictures) no longer provided by Mesa.

No gunsmithing is required to install.

Because the stock and grip interfaces of the Mesa Tactical High-tube telescoping stock adaptor are almost identical to a real AR-15 rifle, this adaptor can accept almost any stock or grip combination made for the AR-15. The only known limitation concerns duckbill style grips that, while they will still fit on the adaptor, would probably need to have the duckbill filed off before use.
