Description
Tokyo Marui M870 & M870 Breacher (Shotgun Shells)
These are spare shotgun shells listed for the Tokyo Marui M870 and M870 Breacher. Tokyo Marui is the Japanese maker whose pump-action shotguns are known for consistent accuracy and smooth actions, and having spare shells is one of the most useful upgrades you can make to any shell-fed shotgun.
Shotgun play is all about reloading: once the shells in the tube are empty you need fresh ones to hand, and a few spare shells in a pouch or on a sling caddy keeps you in the game rather than walking back to the safe zone to refill. These are aimed at owners of the Marui M870 family who want extra shells made for that system.
How they are used
Fill each shell with BBs before the game, using a speed loader if you have one, then load them into the shotgun as the Tokyo Marui manual describes. Keeping loaded shells in a dedicated shell pouch or caddy makes reloading under pressure much quicker. Because shells are easy to drop during a fast reload, many players carry more than they think they need.
Why buy spares
Lost and damaged shells are a normal part of using a shotgun on the field. A spare set means a lost shell does not end your day, and it lets you carry pre-loaded ammunition so you spend more time playing and less time refilling between games.

Compatibility
Listed for the Tokyo Marui M870 and M870 Breacher. Shells are generally specific to the shotgun system they are made for, so do not assume they will fit other makers’ shotguns. If you have a different Marui shotgun, please check with us before ordering. The number of shells in a pack is not stated in this listing; please contact us if you need to confirm it.
Care and maintenance
Keep shells clean and dry, and wipe them off if they are dropped in mud or wet grass, because grit carried into the shotgun causes misfeeds and wears the internals. Load with good-quality seamless BBs and don’t force BBs past the feed lips. Store shells empty, out of direct sunlight, so the feed springs are not held compressed for months at a time.
Who is it for?
These shells are for anyone who already owns a Tokyo Marui M870 or M870 Breacher and wants spare or replacement shells so they can carry more pre-loaded ammunition and keep playing after losing a shell or two.
Please note: The shotgun and BBs are not included.
