Valken Drop-In M4 V12 Airsoft HPA Engine w/ Upgraded Bucking & Nub
As more players are starting to make the move to HPA (high pressure air), Valken now offers a superior system that allows you to transition your current M4 AEG to use HPA tanks — with little to no modification! The Valken V12 Airsoft Engine not only provides improved reliability than an AEG but consistent muzzle velocity and ROF. Designed to be fully programmable, this HPA engine easily drops into many M4 and AR AEGs, including from brands like JG, G&G, and KWA M4 series AEGs! Depending on your configuration (nozzle type and inner barrel length/diameter), you can fully customize muzzle velocity to your liking. This allows you to completely build the airsoft gun you want, giving you full control. The trigger LED interface also allows you to adjust rate of fire, firing modes and the feeding system. And a Mil-Sim lock-out feature is available for special field requirements. Installation is straight forward: simply run wire harness through the rear and drop-in the V12 engine into the lower receiver. The rest of the assembly should be the same as installing a standard M4 AEG (with the exception of the AEG motor and flora pin, which is optional). Additionally, a spare plate is included for compatibility with G&G and WE Tech M4 airsoft AEGs.
NOTE: This H12 Airsoft Engine does not come with a regulator, remote line, compressed air system or small LiPo battery, which you will need to operate this HPA engine.
