Booligan makies a full review of the Deep Fire Enhanced Hop-Up System and this is what he says... "I wasn't really sure what to expect with this kit, as I haven't had any experience with this new hop-up system before. I thought that with some work, the TM system can be as good as you'll ever need. Frankly, this system blows any of the standard hop-up combinations that I've used out of the water in my experience. It is super consistent, has a fantastic air seal, and has the potential to give you a lot higher hop-power than you can get with a standard hop-up.
