EMG / Double Eagle Keltec KSG to M4 Adapter - 2026 Edition

Updated 2026 edition with better fitment and a high-quality, near indestructible, injection moulded polycarbonate M4 magwell.

These adapters allow you to use M4 AEG magazines in your EMG / Double Eagle KSG

• Recessed mag release preventing accidental mag drops

• Internal BB latch that stops BBs from coming back out of adapter on mag change (only drops 2 BBs)

• Compatible with most M4 mags, designed for EPM1/Krytac/Nuprol/ICS

• Massively improves the skirmish-ability of your KSG

• Multi-part construction allows easy installation. Simply remove the two large pins from your KSG lower, remove, place the shell tube part into the KSG, re install the KSG lower and screw the M4 mag-well into the shell tube part (screws included).

• Wings on the outside of the mag-well add stability and prevent wobble within the KSG

Your adapter will come with a number of shims that can be used to ensure snug fitment of your M4 magazine.

For installation: Remove the red screws to separate the magwell from the tube and spacer block

The grey rectangular block is the shim for EMG/Double Eagle KSG's, which reduces lateral movement
