Tired of your AEG gearboxes breaking? Tired of the weight? Then here is a fantastic solution!
These printed gearboxes are drop in fit into your M249, M240 or PKM, and weigh about 4.6oz each, shaving pounds of heavy, metal gearbox away.
Featuring an adjustable and removeable retainer that can accept any cylinder unit, ranging from 59mm to 84mm in body length (Polarstar Jack, F2 and F2 / Wolverine SMP, Inferno / Redline N7) the possibilities are endless. Adjustable retainer can be conviently removed via two screws, allowing you to remove the HPA unit for maintenance without removing the gearbox itself.
Additionally, each kit incorporates a latching button switch that adds a semi/auto selector capability if you so desire. NOTE: The wiring to allow this must be determined on your own. The M240 and M249 kits utilize the charging handle to push the button, the PKM kit must be manually pushed.
Each is designed to use standard M4 length nozzles so no need to purchase replica specific nozzles! However each kit comes with a 0.07" or 0.015" shim to be installed in front of the HPA unit if using an M240 or M249 Nozzle, respectively. NOTE (PKM nozzles are the same as M4 nozzles)
Each kit comes supplied with mounting hardware, the trigger microswitch, and a latching switch.
