Take your AEG to the next level with a revolutionary Piston. It has been redesigned to ensure a premium performance. The Nightstalker piston has eradicated all the common weaknesses of an AEG piston to create an almost flawless design. Firstly, it has been constructed from a reinforced polymer, one that can pull stronger springs without causing damage to itself. It also has a drop-in angle of engagement (AOE) which helps distribute the force evenly on the teeth of the piston rack, reducing the risk of premature wear or breakage.

The stress points of the piston have been revised to spread the wear between 3 contact points and drastically reduce the load on each tooth. Another upgrade is that the piston rails have been revised to reduce friction, this removes the wobbling of the piston against the gearbox and keeps it completely straight. All these revisions and enhancements make for a consistent improvement in FPS and performance. Make your AEG premium, for real.

If you're looking for an upgraded AEG motor with the best price-to-performance ratio, you're looking for the Warhead Industries Base Brushless Motor! This brushless motor was conceived as a more affordable alternative to the legendary Warhead CNC Black Brushless Motor, boasting similar performance at an unbeatable price point. This, the short shaft variant, is designed for AR36, Thompson, AUG and AK AEGs. 

Like the Warhead CNC Black motor used in Bolster Armouries builds, the Base boasts an ESC (electronic speed control) module which protects your battery, provides low-voltage cutoff and regulates speed to keep the immense power of the Base under control. The primary difference between the Base and the CNC Black is that the base uses a cast aluminium housing instead of a CNC machined one and the stator is wound via machines while the CNC Black is hand-wound. 

The advantages of running a brushless motor are numerous, the most important of which is a far higher torque to weight ratio than conventional motors. The lack of brushes means there is less to go wrong and the motor is far quieter when running, guaranteeing a longer lifespan of smooth running performance. That said, these motors are intended for highly upgraded setups so we only recommend them for those who are confident working on AEG internals. If your custom-built beast needs an equally beastly motor to drive it, the Warhead Base Brushless Motor; Short Shaft is one of the best choices out there!

For a sturdy upgrade to your AEG the FPS X-Ring is a piston head seal with a quadrilobate section, which during dynamic stresses are not subject to seal rounding.

X-Rings have less wear than O-Rings as they require less radial pre-stress which results in lower contact pressure.
A lubricant reservoir can be created between the sealing lips using silicone.

Installing this ring will optimise the sealing effect thanks to a better pressure distribution due to the square section.
The X-Ring eliminates any negative effects due to the closing line of the mould, as this is located in the groove between the two lips.
