Krytac P90 Advanced Hop-up Chamber & Inner Barrel O-Ring
The Advanced locking ring is designed to replace the current Oring (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 Oring 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 Oring will ensure the structure is intact.
This in turn will create a dependable system for the BB to travel down the barrel undisturbed for the most consistent and accurate shots.
The new Advanced Oring is also designed longer in size to lock more of the inner barrel and the hop-up chambers surface area to further stabilize the sensitive system.
Testing Axial Movements
It is common for the inner barrel experience movement when installed onto the hop-up chamber. There is currently no brass or plastic ring in the P90 hop-up chamber as stock.
As a result a unsteady inner barrel can affect the BBs hop-up spin hence affecting the accuracy.
Simple Installation of the Advanced Inner Barrel Ring
The Advanced Hop-up Ring is designed to be of perfect fit with the Krytac P90 chamber and flexible enough to fit most inner barrels to create the perfect shim.
Locked Inner Barrel
Once the Advanced ring is installed, the inner barrel will be fully locked into the hop-up chamber with no lateral or axial movements.
Taking it a Step Further
The Advanced Ring is specially designed to be longer with a extruding end that can hold onto more of the inner against the hop-up chamber. This will ensure that is it locked well under such air pressures.
Enhanced Gearbox Seal with increased FPS
A silicone ring is included with the package. The purpose is create a tight fit onto the lower receiver to restrict any movement or vibrations when shooting.
Since the front end of the hop-up chamber will now be locked securely, at the back in parallel there will be improved airseal with the gearbox. The FPS output will then be more stable.
Ultra-Tough Polycarbonate
The Advanced Inner Barrel Ring is manufactured through plastic injection molding using polycarbonate as the material which is lightweight and tough against the stresses while installed into the hop-up chamber.
Tech Work For Installation
There are some instances where the Advanced Hop-up Ring is a little too tight to fit the inner barrel. If its too tight, lightly sand the inside of the Hop-up ring and test fit incrementally with the inner barrel until you achieve a perfect snug fit.
Tech Tip
In general, anything that moves in the rifle especially in the hop-up/ inner barrel should be strictly locked down to eliminate the factors that could affect the consistencies of the shots fired.
