Hey guys, i got a few Buzz Pros off th classifieds and one has a 901 connection. I got some adapters from Good Prophets and the 901 to 510 wont allow my carto to screw all the way in. Also i got a 801 cap and it looks like im going to have the same problem with that adapter as well. any of you guys have any success with adapters on end caps other than 510?
