Home / Shop / Accessories / Magazines / Magazine Accessories / Shotgun to M4 Adapter (TM-M870/Breacher/Golden Eagle/Secutor)
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.
You may be looking at the cheaper options on the market. We have spent a lot of time making sure this adapter is superior.
You may need to remove the shotgun’s loading latch window.
DO NOT EXCEED 150PSI WITH ANY AIRSOFT HPA ADAPTER.
ALWAYS USE AIR REGULATED BY A SECONDARY REGULATOR (EG AT200, WOLVERINE STORM, POLARSTAR MRS).
CHECK YOUR PSI BEFORE CONNECTING AIR TO A HPA ADAPTER.
NEVER CONNECT OUR EQUIPMENT TO PAINTBALL AIR TANKS OR CO2 TANKS.
NEVER CONNECT OUR EQUIPMENT TO A TIPPMAN STYLE HPA LINE
