Tokyo Marui M870 Airsoft Pump Action “Breacher” Gas Shotgun

Built for fast, close-quarters play, the Tokyo Marui M870 Breacher combines compact handling, realistic pump-action operation, and selectable multi-shot performance in a premium gas-powered airsoft shotgun.

Product Overview

At just 515mm long, the M870 Breacher is Tokyo Marui’s compact, pistol-grip take on the classic M870 platform. Its shortened 10-inch-style front end is easy to maneuver through rooms, around barricades, and in other CQB environments. A removable gas reservoir fits inside the pistol grip, while each shell-style magazine carries 30 rounds for immersive, practical operation.

Features & Benefits

  • Selectable 3-shot or 6-shot firing balances BB efficiency with a wider spread.

  • Smooth pump action and rapid-fire capability support quick follow-up shots by holding the trigger and cycling the fore-end.

  • Triple inner-barrel layout with Tokyo Marui’s double hop-up system promotes stable multi-BB flight.

  • Metal receiver, outer barrel, and magazine tube add realistic weight and durability.

  • Integrated 20mm top rail accepts compatible red-dot sights and other optics.

  • Compact pistol-grip configuration provides excellent mobility for indoor and CQB airsoft games.

Common Product Questions

Find quick answers about our airsoft products, shipping and policies.

Can LA Airsoft install this part for me?

Yes. We can build and upgrade Hi-Capas, AAP platforms, and rifles. Choose your base gun and parts, then add the appropriate tech service.

The current custom-build service states that builds are normally completed in approximately 3 to 5 days, with the team reviewing the selected parts for compatibility.

Do I need tools or gunsmithing?

That depends on the upgrade. Simple external parts may be straightforward, but internal upgrades can require disassembly, reassembly, adjustment and testing.

If you are not comfortable working inside your airsoft gun, our team offers professional tech and custom-build services.

How quickly will my order ship?

Orders without preorder items are typically packed the same day when placed before 4:30 p.m. Central Time. Please note that occasional delays can occur during especially busy periods or when staffing is limited.

How should I maintain this product?

Regular maintenance helps preserve performance and reliability. Keep the product clean, follow the manufacturer’s lubrication instructions, and properly manage batteries, gas systems, and internal components. More advanced repairs or internal servicing should be handled by an experienced airsoft technician.

Will this part fit my platform?

Compatibility is product-specific. Check the brand, model, size, and platform named in the product description, such as Tokyo Marui Hi-Capa 4.3 or 5.1, AAP-01, Umarex/VFC Glock, or a particular AEG gearbox type.

Similar-looking parts are not always interchangeable, so contact our team with your exact model if you are unsure.

Will this part increase my FPS?

Not every upgrade increases FPS. Some parts are designed primarily for reliability, cycling speed, weight reduction, or gas efficiency. When a product has a tested FPS claim, it should be stated in the listing.
