Maxx Model Advanced Hop-up Chamber & Inner Barrel O-Ring

The Advanced locking ring is designed to replace the current Maxx O-ring (Normally brass) ring at the end of setting up the hop unit, however, with the original, there is a tendency for a wobbly gap in between the components which would tilt the barrel at an angle.

Once the new o-ring is installed, it will ensure a snug fit to restrict the motion of the barrel that is inside the hop-up chamber. It will secure the inner barrel and maintain itself steadily locked in the true horizontal position. Even when shots are fired, which is the moment where there is the most stress and vibration at the hop-up, the O-ring will ensure the structure is intact.
