Airsoft O-Rings

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.

The set is supplied in a clear polymer organiser case to keep everything neat and includes a set of polymer installation tweezers to make installation without damaging the O-rings considerably easier. If you have a lot of leaky mags gathering dust, this set is the key to giving them a new lease of life!
