Phantom pump, obviously a superior marker but really isn't comparable due to price point.
Autococker pump, a better gun but not that much.
Velocity adjustment is good.
Pump action is good
Feedneck is subrate
This is a great pump for the price and I certainly recommend that you pick one up if you want to go to a pump game in your area. As stated above it is very accurate, simple and relatively light.
Downside is that you will have Roll-Outs. I played an entire day with both All Stars and Nightmare paint and both of them would roll right out of the barrel if I pumped and lowered the barrel even slightly. This talk on the advertisement about some Triad anti-roll system is complete bs.
Other than that and the crappy feed neck you really can't go wrong with this marker. It's the perfect choice for someone who wants to play around with a pump with out the investment. Additionally it has qualities that you wouldn't expect in such a cheap marker, conversely there are some qualities you would... you get what you pay for.
As stated above the strengths of this marker far outweigh it's weaknesses and it's a recommended buy for the casual pump player.
