"If it helps a prospective buyer, I upgraded my Valken battle machine v2 with this hopup and it fit and functioned perfectly without any modifications to the receiver. So far it looks like a night and day difference from the stock one, I'm happy with this hopup!
"I have owned this hop up unit for about a year and a half now and I've got to say it is by far one of the best hop up units I own. I own 2 prowin hop up units as well and I will say that functionality is just as good if not better than the prowin. This hop up can take a wide variety of buckings where as I know the prowin prefers thicker buckings. This hop up is very accurate and super easy to put together and install. I would highly recommend this hop up unit as a replacement for any stock unit that way one can get the best accuracy out of ones gun. The set up I use for my custom built p* jack is this hop up with a modify soft type bucking and an angel custom h-hop nub. I get very accurate and tight groups ~150 feet with .25s and my madbull 300mm 6.03.
"This is buy far one of the best hopup chambers on the market. However it can be a pain to install. I have it and so do two of my friends. When i got it it took a lot of tries to get it in perfect because it has such tight tolerances but once i got it installed right it worked like a charm. However both of my friends had to file a few millimeters off the front of theirs to get it to work with out jamming. But after getting it working it will hit a man size target 3 out of 5 times at 70 yds laser measured with a stock M4. Over all i think this is the best hopup on the market and would highly recommend it.
