empire reloader w/sound activated
68/4500 crossfire hpa carbon fiber
dead on drop foward w/on-off
stock j&j 2 piece barrel
-maybe a barrel kit, but stock j&j 2 piece works great with most paints. (I use marbs or evil and it shoots dead on every time; I also keep my paint in a cooler out of the sun and the humidity so the paintballs don't change shape as much)
-ult trigger kit if you want to shoot faster
-Lvl 10 may need to be tweaked
-Somewhat of a gas hog
I have had the Tac One for almost 2 full seasons and have shot alot of paint thru it. The marker still works flawlessly and have had very few ball breaks (all have been in the barrel). The marker shoots fairly consistant out of the box, but once the regulator in the valve and on your hpa tank are broken in, it is very consistant. This marker is very accurate within the 100' range and anything farther just put a little arc on the shot and you'll still have a good chance of hitting you target (I've gone up against some of those new Apex barrels shooting from a distance and have managed to take them out w/ the stock barrel). I like to use marbilizer and evil type paint thru the marker and they give me nice straight shots almost everytime, but i've also shot low end paint from Gander Mountain and Wal-Mart and the marker shoots it just about as accurate as the good paint.
Air Gun Designs also put forth the effort in making the Tac One with exceptional quality and duribility. The Tac One is as durable as any Tippman and has the quality of any high end marker. It may not look as fancy as a high end, but once you see it and hold it, you'll know what I mean (it has it's own unique, cool look to it and you'll notice out of the corner of your eye everyone at the field checking it out). The marker itself is small, compact, and lightweight and once everything is on it (hpa, hopper, etc...) it's still not overly heavy and is easy to manuever.
DURABILITY is a big thing for me. I've always had tippman 98's and the pro carbine because I know I can depend on them every time we go out. Add the Tac One to the list as well. My marker has been in hot, humid weather, cold weather, heavy rain, mud, banged up against trees, slammed into the ground when diving and still performs well. Sometimes after a long day I get lazy and won't clean the marker, just leave it in the garage, come back 2 weeks later, put some oil in the on/off, take the barrell off, dry fire it about 15-20 times and its good to go (although I recommend cleaning it so it looks pretty the next time you go out).
If you ever have problems w/the marker there is plenty of support over there at the Automag forum, but I would bet that most of the Tac Ones are problem free out of the box.
On a side note: once the lvl 10 is broke-in, it may need to be adjusted with the springs and shims. With some guess and check work, a person should be able to figure it out, but if your like me with not much time, you can ship the tac one to a few well known airsmiths from the automag forum. For myself, I sent the marker to Tunaman to have the lvl 10 adjusted, it took awhile to get the gun back due to him being very busy, but was worth it because it has worked flawlessly for the past year.
Overall, you can't go wrong with the tac-one. It's perfect for scenario or any rec or open play games and even speedball w/the ult trigger. Other than a tippman, it gives you the most bang for your buck in my opinion and is a perfect upgrade from a tippman or spyder if you want to spend the extra money.
