Mesa Tactical Leo Gen 2 Telescoping Stock Adapter for Remington 870

The Mesa Tactical LEO Gen 2 Telescoping Stock Adapter for Remington 870 transforms your shotgun's ergonomics and handling by letting you mount AR-15 style collapsible stocks and pistol grips. Purpose-built for tactical and law enforcement use, this adapter keeps your iron sights or bead sight fully functional while giving you the adjustability and control that modern operators expect. If you're running a Remington 870 and want the modularity of an AR platform buttstock without losing sight picture, this is the system that makes it possible.

The Gen 2 design refines what made the original LEO adapter popular. Mesa Tactical shortened and compacted the profile, angled the pistol grip forward (like a 1911) to give your thumb web more room, and repositioned the endplate so it sits lower on the sides—meaning less contact with your face during recoil. The result is a shotgun that handles more like an AR-15 while keeping the raw power and reliability of your 870. The adapter itself is investment-cast aircraft-grade aluminum, CNC machined and powdercoated to handle hard use. Length of pull adjusts to fit your frame or to accommodate body armor and kit, and sling attachment loops are built in.

Mesa Tactical offers the LEO Gen 2 in multiple configurations—adapter only, recoil starter packs, or complete stock kits. If you opt for the full kits, you get an ERGO beavertail grip included. For shooters who want to tame recoil further, an optional Kynshot Hydraulic Recoil Buffer (Mil-spec) reduces felt recoil and improves shot-to-shot control. Setup requires no gunsmithing.

Frequently Asked Questions

Will the LEO Gen 2 adapter work with my Remington 870 bead sight?

Yes. The adapter is designed to maintain a lower stock elevation that keeps your existing open sights or bead sight in full use. You don't sacrifice sight picture when you upgrade to AR-style controls.

What AR-15 grips and stocks fit the LEO Gen 2?

Standard AR-15 telescoping stocks and pistol grips attach to the adapter. Mesa Tactical's complete kits include an ERGO beavertail grip, which works especially well with the Gen 2's forward-angled grip geometry. Any milspec AR-15 component should be compatible.

Can I adjust the length of pull on this adapter?

Yes. The telescoping buttstock allows you to adjust length of pull to fit your body size, shooting stance, or to accommodate body armor and tactical gear.

Does this adapter require gunsmithing to install?

No. The LEO Gen 2 installs without gunsmithing. It replaces your factory stock and attaches directly to your shotgun.

What kit options does Mesa Tactical offer?

The LEO Gen 2 is available as an adapter-only kit, recoil starter packs, or complete stock kits. Upgraded versions can include an optional Kynshot Hydraulic Recoil Buffer to reduce felt recoil.
