"This is a great hopup unit. I have installed it in several different guns over time and it has never failed. The one complaint that I have is that it tends to be very stiff I MEAN VERY STIFF. The problem can be fixed though with some silicone oil (just don't ad to much).

"this was a great product and it worked fine, after 500 rounds it jammed once and its a great hop up, not much to say but i got it today and i was testing it out and the first jam and i looked in the hop up (im stupid so dont comment) and accidentally fired, the bb ejected out the hop up and hit me in the eyelid and i was fortunate enough to keep my eye without vision problems. A word of the wise - "WEAR EYE PROTECTION WHEN USING AN AIRSOFT GUN NO MATTER IF ITS IN A GAME OR TARGET PRACTICE!"

"This is a good hop up unit, however I've had a problem with two separate units. The adjustment wheel lost the ability to hold a setting and would loosen up with shooting. There is a screw that holds the adjustment wheel down, which was the obvious thing to tighten for a fix, but it could not be tightened to prevent the adjustment slippage. I cut a little piece of aluminum soda can to about half the size of a dime and put a notch in it, kind of like a horse shoe, then used this to slide under the adjustment wheel. This little shim was enough to keep the adjustment. It's a kind of a MacGyver/kluge fix, but at least it is covered and has held up over several games and it still allows adjustment.

Although the G&P bucking it comes with works ok, I've been really pleased with the results of using a Prometheus bucking and Angel Custom "H" Nub. This combo makes a great seal and delivers good accuracy with tight bore barrel.
