TAPP Airsoft Tapp M4 Adapter for KSG Shotgun | Modular Series
The Tapp M4 Modular Adapter converts your traditional airsoft gun to use HPA and accept standard M4 AEG magazines (super-feed mags recommended).
“It’s a solid idea but terrible execution from Tapp. The thing comes in two pieces and is quite difficult to install once the first piece in the gun. Finally got it running and it will only feed a single bb at a time unless you tilt the whole gun down to let gravity help feed. Not super useful for a pump shotgun to feed one at a time…I was using pretty new EPM1s (aka super hard springs) and still no luck. Tried the Krytac 150s, a VFC hi cap, and even an electric winding drum. All the same problem. Super disappointed and will be returning it. Use the $110 on this for more TM shells since cyma shells are a bit finicky in it as well. Tm shells work flawlessly in 3 and 6 shot mode.”
