This adapter will work in both clone and TM MK23s. They are each individually tested before they ship.

THIS ADAPTER IS READY TO BE USED OUT THE BOX. THERE IS NO NEED FOR DONOR PARTS, THEY ARE PROVIDED AND FITTED

We’ve replicated a MK23 magazine, and add adapted it to take 30 round shotgun shells. A BB latch to prevent dropped balls and simple push mag release on the bottom of the adapter make this a snipers dream!

The adapter comes with a 15cm airline and a beautiful Foster 22 (US Style) connector fitted. 

US style fitting can easily be swapped to EU fitting listed here

With a Clone MK23/SSX, field limits can be achieved around 120-130PSI on a 0.25g BB. I strongly recommend using heavier BBs with this adapter, as these BBs spend more time accelerating in the barrel, and a higher FPS can be achieved relative to PSI (make sure your site chrono’s you on the weight you are going to be using)
