Airsoft Gun Internal Upgrade Parts

Gearbox, Hop Up Units, Inner Barrels, ETC!

Airsoft GI has worked with enough airsoft guns to know that what’s inside really counts. If your airsoft gun has a broken mechanism or has simply fallen behind the times, our internal upgrade parts will have you back in the game. We have airsoft gun internal parts for AEGs, spring sniper rifles and gas blowback pistols and rifles. Add aftermarket AEG cylinder heads to maximize compression or install a precision inner barrel for better accuracy. Replace a burned-out stock motor with a standard OEM motor or upgrade to a high torque model that can handle other internal upgrades.

Our gas airsoft internal upgrades include recoil springs that increase felt recoil, loading nozzles that improve durability and high flow valves to increase FPS velocity. You can upgrade your spring rifle as well with parts that give your shots more distance and more precision. We carry parts from all the leading airsoft parts manufacturers such as Action Army, Danger Werx, G&G, Modify, SHS, and Lonex – and we make some of our own internal airsoft parts. Full tech support comes with every purchase, so you can turn to us if you encounter troubles while you work.
