It's not my favorite regulator, but it works. Truth be told there are hundreds of dollars worth of upgrades I would love to put into this gun, but I need to figure out an order starting with something I that will improve it the most down to what is just icing. Also, considering cost.
I was thinking about going to this company and having them do the ultralight milling and cut some windows in it. Should take off 3-4oz from the weight. http://www.eliapaintball.com/home.html
Maybe also have them mill it to accept BB eyes and NXT detents. That or just buy an NXT body, then have them do the ultralight milling on that.
Then since it has big windows a clear can(where do I get these?), a new ASA, Kila detents, and see if I can find an SFT threaded stiffi.
Then maybe a new board, I've always had good luck with tadao.
The HE bolt will work for awhile, but maybe an eigenbolt with a spring.
EDIT: an NXT body might be a good investment.
