Hi everyone I'm new to the site and I'm looking for some expertise, I have recently purchased a tippmann omega m4 and out the box it's pretty much trash, I want to buy a new hop up for it and I've been looking at the maxx and the prowin. What is the difference between them as the maxx is pretty much double the price, I'm going to get the prommy purple hop up rubber or the g&g green and a new barrel down the line, I would like to see what you guys think and thankyou.
