Product information

The Tokyo Marui M870 Breacher is a compact gas-powered pump-action shotgun. Tokyo Marui lists a 515 mm overall length, 197 mm barrel, 2,200 g weight and a 30-BB shell feeding system.

The selectable mechanism fires three or six BBs per pump and uses the company’s double-hop arrangement. Gas output varies substantially with temperature and propellant, so no universal UK FPS is stored.

Enter FPS and BB weight to calculate muzzle energy.

Published figures are a reference, not your replica’s chrono result. Equivalent speeds assume the same energy; changing BB weight can change measured energy. Check your own readings and your field’s limits.
