Mesa Tactical 20GA to 12GA Stock Adapter – Remington 870

The Mesa Tactical 20-gauge to 12-gauge Stock Adapter allows you to install 12-gauge stocks and pistol grips on your Remington 870 20-gauge shotgun. This adapter bridges the dimensional gap between the smaller 20-gauge receiver and standard 12-gauge stock mounting systems, giving you access to a wider range of aftermarket stocks, tactical furniture, and collapsible stock options designed for the more common 12-gauge platform. It's ideal for shooters who want to customize their 20-gauge 870 with modern stock configurations or upgrade to adjustable length-of-pull systems.

Machined from steel with a durable black finish, the adapter installs between the receiver and stock, maintaining a secure fit without permanent modification to the firearm. Installation is straightforward for users familiar with basic shotgun disassembly and requires no gunsmithing. The adapter maintains proper alignment and provides a solid foundation for stock mounting hardware.
