If you're the techy type and want to maximise your AEG's efficiency, the Bolster Armouries HOP-up to Barrel O-Ring Shim Set belongs in your toolbox! This set includes 10 o-rings designed to fit around the HOP-up unit and inner barrel, forcing it back to meet the gearbox as seamlessly as possible to promote maximum efficiency and reduce shot-to-shot FPS deviation.

This set is designed to replace the "one size fits all" HOP-up unit spring, providing a user-customisable solution to account for manufacturing tolerances. While this will take a bit of trial and error to get the perfect fit for your AEG it should prevent airseal qualities from reducing over time and avoid that annoying realisation that you forgot to reinstall the HOP-up spring after upgrading or maintenance!

The Bolster Armouries HOP-up to Barrel O-Ring Shim set should fit almost every AEG on the market and you probably won't need to use the full set, meaning you might even be able to replace two HOP-up springs with a single set.

If you're looking for a sturdy upgrade to your AEG, you can't get any better than something from Bolster Armouries. This O-ring is constructed from high-density rubber and provides a superior seal to increase the reliability and lifespan of your Airsoft rifle. This O-ring can improve your air seal consistency, which can result in increased accuracy. This o-ring is compatible with most AEG piston heads.

Bolster Armouries EZO Ball-Bearing Bushings are designed and manufactured by Sapparo Precision Inc. in Japan and have been chosen by the Bolster team thanks to their extremely low friction, high-quality steel construction and fantastic reputation in a wide range of industries.

Specialists in medium and miniature ball bearings, Sapporo Precision bearings have a wide range of applications; in this case, reducing friction and extending the lifespan of whichever AEG they're installed inside. These bearings allow the gears to spin freely at a tremendous rate under high stress with minimal chances of failure, all while reducing stress on the gearbox shell and gear axles.

These are the same bearings used in Bolster Armouries' ultra high-end ONYX [Violet Edition] and ONYX [Blackout] builds and have performed phenomenally, proving to be far stronger than the average ball-bearing bushings. Compatibility-wise, these EZO Bearings will fit any AEG gearbox shell with 8mm bushing holes. If you want a super slick smooth running AEG build, Bolster Armouries EZO 8mm Japanese Steel Ball Bearing Bushing Set belong inside! 

The Bolster Armouries AOE Correction Washer is the perfect easy upgrade for your Airsoft AEG. It fits behind the piston head and ensures your replica has the perfect angle of engagement. This is the angle at which the first tooth of the piston toothing comes into contact with the toothing of the sector gear. If the AOE is incorrectly adjusted, the piston guiding rails and the first piston tooth are subjected to increased wear.

The correct AOE adjustment significantly increases the lifetime of a piston, it can also reduce the chance of your Airsoft platform jamming, which often occurs when the angle of correction is not correct. The FPS will also be more consistent due to a smoother and more precise engagement when firing the AEG.

Treat your Airsoft AEG to the Bolster Armouries AOE Correction Washer and watch as its performance becomes more consistent and the piston survives many more skirmishes.
