This is a one of a kind marker. No other paintgun looks like it or works like it. The marker is fed through a magazine attached to the bottom (simulates a real weapon) and works sort of like a conveyor belt.
When working properly, this gun ROCKS. 12+ balls per second on full auto and highly accurate. Semi-auto is even more accurate and both modes can really 'reach out and touch someone'. For long games, a hopper attached to the marker is best in order to carry a sufficient amount of paint. Nitro/compressed air seems to be the better option though Co2 works with care in the setup. The marker is also well made and as another reviewer mentioned, it does not need mods other than maybe a dot sight because of the out-of-the-box potency. Good/fresh paint is key.
This is a great looking select fire marker with better accuracy then most. It has a good Rate OF Fire and rarely breaks paint when properly setup. It is loud which is great for intimidation purposes or realizm.
I do not recommend this marker as a FIRST paintgun. Specifically if you will use Co2 and have varying climates. The cold and high heat wreak havoc on Co2 and will cause problems with the marker. I play in this type of weather and have had to purchase extra accessories in order to play decently. Remotes, X-chambers, and regulators would be some of the mods needed to play in the cold or extreme heat with Co2. I have heard that nitro works very well but can't vouch for it since I only use Co2. The AT85 needs to be well cared for which isn't a BAD thing but won't appeal to those who want to play and then throw the marker in a closet. Maintenance is necessary. With the Co2 setup, I have had days where the marker worked very well, and others where I have had to switch to my backups because of feed problems or co2/weather related problems. Good paint is also needed.
It is loud so sniper style players may not appreciate it though the accuracy is excellent.
Out of the box, this marker can kick butt. Having the hopper version is great when using decent amounts of paint. Upgrading or 'tricking out' is not necessary other than maybe a dot sight. The only upgrades might be if you want to use Co2 with the least amounts of problems (remote/X-chamber/regulator). Accuracy is top notch and it has very good distance. Look and feel are excellent. As i said before, the marker is well made with exception of the magazine which seems a bit flimsy compared to the marker itself.
Definately worth the cost of $450-$550 as long as it is well kept. It is a one-of-a-kind marker.
ROF will keep up with most if not all Electros, accuracy is on par if not better than a Cocker or pump, range is better than most markers.
I would recommend this marker to anyone who is not afraid of taking their markers apart and who has the availability of a backup if needed.
Because of the possible problems you may encounter. I do not recommend this as your only marker.
I also do not recommend it to those who do not like the 'cleanup and maintenance' part of paintball.
