M870 Magazine Adapter

M4 Magazine adapters for TM M870 and breacher gas shotguns.

  • Internal feed disconnect allows the adapter to be removed or installed with a full magazine fitted
  • Ambidextrous magazine release for convenient reloading
  • Two versions available:
    • Shell loading gate compatible – magazine well has a cut-out which allows the adapter to be fitted without having to remove the shot-shell loading gate
    • Non-compatible – requires the loading gate to be removed, but allows the magazine to sit closer into the receiver and gives a cleaner look

Note that while the adapters are tested with a range of  popular M4 magazine brands, they are not guaranteed to work reliably with every type.
