Personally, I think Bob makes the best paintball marker to date! I have owned an Invert Mini 3rd gen, Victory V1, Angel A1, 2012 Demon, Nt11, Dm12, Ego 11, and my 2k12 G6r Elite. If you have a pressure tester, dow 55, allens, and a brain you can make any Bob gun shoot magic. They are simple to maintain and smooth like a spool. My Angel was a nightmare. The bolt stick was awfull. After doing the breach seal mod and all the other tips mike put on his video the marker shot nice for one day then it was back to the nightmare.
