Maybe I'm lucky?
I know I get the same results with my GBBRs using the PDI, and same thing when I use the Reaps A+ rubber. When I engage hop to the right setting I get around a 12FPS drop with both rubber types. Doesn't affect range or accuracy in any negative fashion, only dat +.  |
What spring are you using to get 395 FPS? With a perfect air seal you can do that with a M100. I think the FPS drops are from the opening in the middle, as the BB is passing through the hop up rubber air escapes through that. That's my theory anyway.
Aside from the FPS loss the rubbers shoot decently well.
