Product Information:
Ok, for starters, the BB catch works like a charm however, you will always lose one BB due to it being in the magazine feed in between the hopup and the magazine catch. But just one, not 3-5... Secondly, the adjustment wheel is huuuuge, which comes in handy if your wearing gloves. The bucking was a little too long, about 2mm for my bravo 6.03mm barrel, so I had to trim a little off of the end to allow the barrel lock to fit correctly. The hop up is really good as well, you can wdjust it to the point that the bb can come nack at you ;). The LED assembly is awesom as well, it allows for the BBs to be charged without a huge flash at the end of your barrel which could potentially give away your position (if playing at night). This hop up is very nice and fits snug into my madbull Noveske body. The only problem I am having, and I haven't quite narrowed it down is that I have lost significant fps going from the stock echo1 m8a4 plastic body and hop up to the madbull Noveske medal upper and lower/ultimate hop up 3-1. I'm talking 20-30 fps... I don't know if it is the outter barrel and hop up connection, or the fact that there is no BB ramp or what, but my gun before was shooting 370-380 with .28 and now is shooting 345-350 with .28...? (yes I meant .28)... But overall very satisfied with this hop up.

One solid piece. Huge adjustment wheel. Has led attachment. Has BB catch.

Adjustment wheel almost too big. Gets in the way of a mock bolt for someone that likes to use them. Orrr, if you use the Madbull JP CTR-02 upper receiver for example, that doesn't use an ejection port cover (you NEED a mock bolt to keep your internals clean). Possible, somehow, loss of air pressure if not using madbull outer barrel and or body...? (because the madbull outter barrel fits with a madbull metal body better and the hop up fits with a madbull outter barrel better. I had to force this hopup to fit in my stock echo 1 outter barrel.
