If you are fitting an upgrade nub into the MWS gas rifle, it is one of the cheapest upgrades you can do with great gains compared to the standard setup.
There is however an inherent issue in regards to how the hop pushes on the nubs. No matter which nub you are using the arm will rotate the nub towards the rear of the hop unit. This means even though you may be using a nub that has a larger contact area, when hop is applied the nub rotates and you don’t benefit from the full contact patch as it applies pressure on the corner.
The Jaeger Precision Titan Nub fixes this by adding more contact point to keep the nub straight as it is pushed downwards. There is only so much contact patch you can get with the standard hop up unit however I feel this is the best way to maximise contact through the pressure path of the hop arm. The guide fins will keep the nub centre and straight for the best possible pressure.
As far as I am aware no one has thought about this yet and that is why the Titan Nub was designed from scratch based on the success of the Jaeger Precision MDR nub.
