- description
Designed for TM M870, Breacher, Golden Eagle and Secutor-pattern shotguns, this adapter lets you feed a standard M4 AEG magazine from the shell-tube area, and holds it at a more aggressive angle than typical shotgun-to-M4 adapters for a cleaner, more natural handling position.
It's full of practical detail: adjustable side shims (which unscrew and flip to suit wider magwells), a rear screw to take out vertical play, and built-in BB retention to stop pellets spilling on reload. The M4 magwell is injection-moulded polycarbonate with polished internals, so it feeds smoothly and laughs off BB strikes.
