The ultimate HPA adapter for MK23
This adapter transforms your replica by routing BBs to the nozzle from an AEG magazine (M4 or MP5) mounted on the accessory rail or handguard of your MK23/SSX303. A lightweight HPA unit replaces your gas magazine, giving you unparalleled consistency and capacity.
This kit puts the magazine in the perfect place for holstering and use as a rifle (maybe in a carbine kit!).

Shimming the HPA Section for Perfect Air Seal:
To factor in manufacturing tolerances of the MK23 pistols, we have made the height of the HPA section adjustable. To adjust the height, unscrew the HPA section using the two screws in the baseplate, and place the 0.25mm shims inbetween the two sections, before re-assembling.
