The internals of the airsoft gun is what makes it reliable and durable. The internals of the gun is directly responsible for the way your gun works and perform. For AEG's it is especially important because the internal gearbox plays a huge role in the system. Don't forget if you don't have any knowledge about basic weaponsmithing, we strongly advise to have it done by a professional. Internals are a good way to upgrade and modify your weapon to your preference. Like a stronger spring for more FPS or a faster engine for more bb's per second. Whatever it is here you will find everything you need for you AEG's. If you need any help do not hesitate to contact us.

Airsoft AEG Internals Spring

The spring is the main component of power inside the gearbox. It pushes the piston forward and compresses the air inside the cylinder resulting in firing a bb. Springs need to be replaced when your current gun doesn't shoot the desired fps or the springs has broken. For AEG springs we recommend the Nuprol M110 Spring (Aeg), suited for an AEG that fires at 360 fps but it should be used as a guide as every weapon is different.

Airsoft AEG Internals Piston

Pistons are the workhorse of the gun. It has to take a lot of conflicting energy. Because the gears are pulling it back and it pushes, as previously said, the spring forward to fire the bb. Therefore pistons break quite often. Fortunately, pistons are not expensive. The Nuprol 14 Steel Teeth Piston is an excellent choice for a piston, just be sure to count the right amount of teeth to match up with the sector gear.
