I would love to get some next gen bumpers that actually hold up MUCH longer than the clear level 10 ones (so you know, like more than 3-4 times out, lol).

What are you running, or specifically how are you running your mags that are destroying a bumper? Not that i have teched thousands of guns or anything, but i suspect i know the reason why.

The clear bumpers get destroyed on a level 10 bolt due to stretch and tearing. It doesn't happen on level 7 bolts because the contact area at the back of the level 7 bolts is larger which spreads the force over a larger bumper area, which results in less distortion of the bumper and less tearing. The tearing can be reduced by gluing the bumper to the face of the valve. This holds the bumper in place and reduces tearing.

Just a normal xvalve level 10 set up. like athomas said, the problem is basically the inner ring touching the bolt stem frays and starts to tear away. I have done the glue trick, which does help.

This bumper should cover all the bases, regardless of what anyone's pet theory is (unless said theory is far-fetched and not based on any logic, evidence, or data whatsoever).

The material is more durable, less "tacky" on the top surface, it's dead simple to print, and it costs like 1/20th what a clear bumper costs.

And never shall glue touch your valve, for glue is an abomination and shall be unclean unto thee.

The only question is the long term durability and impact performance.

The model is on Onshape if anyone wants to go find a local printer with 85A Ninjaflex and try one out. I used 0.8 perimeter, 0.6 top and bottom, 30% infill.
