set of o-rings for pressurizing the AEG hop chamber

Set of 14 O-rings for pressing the chamber against the gearbox.
O-rings are slid onto the inner barrel instead of a spring and push the chamber more against the gearbox. This extends the lifespan of the gearbox and, most importantly, improves performance consistency.
The optimal number of rings is such that the body can be closed with a pin, and at the same time, the chamber is firmly pressed against the gearbox.
O-rings absorb the energy of the gearbox better than a spring, and the chamber does not bounce off, so the performance remains within a dispersion of less than 1 m/s in well-tuned assemblies. Installation usually achieves a slight increase in performance and extends the lifespan of the gearbox.

sizes of O-rings:

12/8 mm

10/6 mm

11/7 mm

Installation is easy and does not require specialized knowledge (except for basic disassembly of the weapon to access the chamber), and by installing this set, you will not void the weapon's warranty.

In the package, you will find 14 O-rings (sufficient for 2-3 chamber pressings depending on the model of the external barrel manufacturer)
