I bought this gun off of someone on Craigslist for about $380, used. This is probably one of the best guns i've ever used/tested. Not only is the gun accurate, maintenance is almost something that you would want to do as an everyday chore.
As always, let's start off with the Weakness(es):
One Weakness (if can even be called that) is the Kick. Like i said i bought my gun used, so it was obviously already broken into. I can see how people can say that it has alot of Kick, i'll admit that it's not the quietest marker on the market, however i think that the volume of the Kick is often over exaggerated.
The only other Weakness that i've experienced is minor Chopping. I found that when i chrono-ed my gun i was shootin at least 285 FPS and was suffering from maybe 1-3 breaks per every 100-150 balls shot. Once i re-chrono-ed my gun and adjusted it to 265 FPS i haven't experienced a break since.
This is probably one of the most accurate guns i've shot, and it's manufacturer certainly does add some credibility (having produced the Ego series, etc.). When i dropped my FPS from 285 to 265, i saw little difference in drop off and distance. Of course i've only had this gun for a couple months and am still experimenting with certain aspects of it. But nonetheless, this marker has exceeded my expectations.
This marker is by far the easiest marker to maintain as far as Poppet markers go. Take out the bolt, run a squeegee through, unscrew the backcap, clean/lube the rammer and you're set. Nuff' said.
For this marker i'd recommend first of all getting a Cure (2) bolt to prevent/assist in getting rid of any excess chopping.
Next a Zick Kit for those that like to complain about the Kick that is oh so annoying.....
And finally, if you decide to not go the route of getting a Star Frame, i'd suggest at least getting another grip. The main reason being that the stock grips are way to bulky. Also, it's not really necessary, but a new trigger wouldn't hurt either. If you do decide to go the Star Frame route, then you won't really need either Grips or a Trigger because the Star Frame has both, including a LCD screen.
I'd recommend this product to anyone in the intermediate level of paintballing. The main reason why is because of the trigger sensitivity and the grips. Overall, this is a great marker with minimal upgrades needed and great performance.
