After 3 months I a problem with the 510. It is press fit, and atty's don't sit flush. If you use it as a daily beater, the 510 will fail.
My Solution:
The Varitube 14mm spring loaded 510 just fits with the retaining nut. I didn't have a M10x0.5 tap, if you do, you can tape the enclosure and screw the 510 directly into the mod. Total cost of the repair was $5 plus some time. Huge improvement, this is the way they should come from Cloupor.
Great mod otherwise.
