This adapter allows you to use an M4 AEG magazine with your 870-style shotgun

Our adapter holds the magazine at a more aggressive angle than traditional shotgun to M4 adapters. It also packs a bunch of extra features!

Adjustable side shims to prevent wobble (shims can be unscrewed and 'flipped' to further reduce wobble for shotguns with wider magwells)
Rear adjustment screw to reduce vertical movement of adapter in gun
BB retention to prevent lost BBs on reload

The M4 magwell of this adapter is made of injection moulded polycarbonate, making it impervious to BB strikes. Its polished internals make reloading a breeze.

Plug and Play

This adapter is ready to go out of the box. Valve, feed lips, and gas router are already fitted to the adapter. You do not need to use any donor parts.
No assembly is required.

M4 Adapter Information

Injection moulded from polycarbonate, this magwell is near indestructible!
Compatible with most airsoft M4 magazines.
- We recommend EPM1/EPM1s magazines as they have excellent fitment and strong springs.
- Magazines advertised as Fast Feed such as the original EPM or Amarok magazines will also work well
BB retention means only 2-3 BBs are dropped when changing mag
A swappable rear shim is included
Please note only 2 screws are required to attach the modular magwell, some adapters may have more

You may need to remove the shotgun's loading latch window.
