Mesa Tactical Leo Gen 2 Telescoping Stock Kit for Remington 870

The Mesa Tactical Leo Gen 2 Telescoping Stock Kit for Remington 870 transforms your shotgun with AR-15–style ergonomics and adjustable length of pull—a purpose-built system designed for law enforcement, tactical operators, and serious shooters who demand professional-grade performance. This complete kit replaces the factory stock with an investment-cast aluminum adapter that accepts standard AR-15 collapsible buttstocks and pistol grips, giving your 870 the handling characteristics and versatility of a modern rifle platform without gunsmithing.

The Gen 2 design refines every detail based on operator feedback. The adapter is more compact than earlier versions, with a forward-angled pistol grip (modeled after M1911 geometry) that creates thumb space and accepts high-comfort beavertail grips like the included ERGO grip. The end-plate geometry sits lower on the sides, reducing contact under recoil. A low sight-line keeps your iron sights or bead on target. Multiple sling attachment points—including Mesa Tactical's signature pocket-hook loops—adapt to any carry style. Adjustable length of pull means one shotgun fits shooters of different builds, accommodates body armor, and lets you fine-tune your shooting position instantly.

This kit includes everything to start: the Leo adapter, M4-style telescoping buttstock assembly, ERGO pistol grip, steel stock wrench, and push-button sling swivel. For shooters prioritizing recoil control and shot placement, Mesa Tactical offers optional Kynshot Hydraulic Recoil Buffer upgrades that can reduce felt recoil by up to 70%—a feature favored by professional operators requiring sustained accuracy.

Frequently Asked Questions

Will this work on other shotgun models besides the Remington 870?

The Mesa Tactical Leo Gen 2 is designed specifically for the Remington 870. Mesa Tactical makes separate adapters for Mossberg 500/590 and Beretta 1301 shotguns.

What's included in the complete kit?

The complete Leo Gen 2 Stock Kit includes the adapter, an M4-style telescoping buttstock, an ERGO pistol grip, a stamped steel stock wrench for installation, and a push-button sling swivel. A rubber butt pad is available as a separate purchase.

Can I adjust the length of pull, and why would I need to?

Yes—the telescoping buttstock is fully adjustable. This lets you accommodate different shooter sizes, or quickly change length of pull when wearing body armor or tactical gear. Adjustable length of pull also helps you maintain a consistent, comfortable shooting position.

Does the Leo adapter interfere with my iron sights?

No. The Leo Gen 2 adapter is designed with a low sight-line, so your factory bead or iron sights remain fully functional and unobstructed.
