Bolster Armouries HOP-up to Barrel O-Ring Shim Set

Bolster Armouries
Code: BA-HOPRINGS
5.99
  • Rubber construction
  • Replaces the HOP-up unit spring
  • Provides superb air seal

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.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
