Well, since I have only been playing paintball for a short period of time (loving it by the way). I have a limited perspective of paintball guns and gear. The Eos is my first gun that I've owned. But from using it a few times, on scenario play as well as some bush ball. The gun has performed as expected. My first time using it was just in the back yard shooting a board about 20-25 ft away....Right out of the box, put things together, loaded up some paintballs and let her rip. This gun has impressed me right out of the box. After shooting 500-600 rounds it ran out of gas (and didn't chop a single ball). So the next step, get to a field, get some gas and play.
My first time out with the gun, I used a 48/3000 pure energy tank and Halo B hopper. Performed flawlessly, no chopped balls shot fairly accurately and chrono'd at 223, 227, 234, 225 fps (field was limited to 230fps) so no tuning required for me anyways. Just got out there, and was able to peg off a few people from a distance, a 10fold improvement over the a5 or bt-4 which I was used to. The next few times using the gun went well, chopped a ball in the bush, but was able to play through it. This last time playing (after cleaning and greasing things) it chopped a ball right off the bat (was using low end paintballs....unfortunately and chrono'd at 227, 235, 227) and shot like garbage. Splitting balls right out of the barrel...As well had balls that were slicing every which way, cutting a good 48 inches. But once back to a decent ball it came back around firing well. This time air lasted just about 500 balls or so.
Now the Review
Size: Is good for me anyways...I am 6'3'' and had looked at the mini, the ion, and such, but nothing fit me as well as this gun does. Itís only about a pound or so, not to heavy, not to light either. So it gets a 9/10
Trigger: Is not too bad, for a beginner to 'walk' the trigger is semi difficult to do. Probably need more practice and what not, but I do like the feel of the trigger. It is about a 1/8th to 1/4 inch pull to fire. For me, itís not bad, could be a little shorter, but it can be adjusted. From use so far, I havenít noticed a lot of trigger wobble (side to side) it does but not enough to effect play of any sort. (I've used my brotherís danger power f8 and that trigger is amazing). Trigger gets a 7/10
Grips: They serve their purpose. Not a huge fan of how they appear but heck no one see's them under you hands anyways. They don't really match the gun well, the coloring is off, but they are comfortable. Grips get a 7/10
Overall Appearance: I have the black and red Eos with the freak barrel kit; Love the looks of it except for the grips. There is one thing I dislike is the red flashing power light. It gives you away in low light situations, but Iím sure black tape will solve that problem. In comparison to my brothers DP F8, I like the Eos 9/10
Disassembly/Assembly: I have pulled some of it apart and was fairly easy to do. The bolt out the back is great and simple. Accessing the board is simple 2 screws on the grips and there you go. 9.5/10
After play simple maintenance: Piece of Cake. Bolt out the back, unscrew feed neck, take off barrel, squeegee. 10/10
Board Programming: Well at first it was confusing, dwell settings, rate of fire, etc...But once understood, it is fairly simple yet a little annoying. To program you must take off one side of the grips (annoying if wanting to switch anything), and press a little button to get into the proper setting. Once on the setting you wish to change you hit the power button a certain number of times to change that setting and pull the trigger to save. A yellow and red light tells you in which direction you are changing that setting (yellow increasing, red decreasing for the most part). Compared to my brothers F8 the programming is rather difficult to do (the f8 just has switches you flip up or down to program certain things) the rating it gets for programming. 8/10
Accuracy: Is pretty good...from about 40 ft it is possible to shoot 10 balls within a 16 inch radius (If you are using a decent paintball, garbage paintballs will split or tail off). After using a stock bt-4 and an A5 (from my experience anyways) the Eos is one heck of an improvement (lucky to keep it within a 24-30 inch radius from 40ft with a bt-4). But if you chop a ball and shoot, it seems like it will stick to one side (this happened while I was using low end balls), hence the slicing/splitting. But once cleared and back to a decent ball it shot like normal. So if you chop a ball....squeegee it a.s.a.p., and get back in the game for some more fun. 8.5/10
Eyes: So far havenít been too bad. I've shot probably close to 3000-4000 balls (500 low end balls) and have only chopped 2 balls so far. 9/10
Air Usage: For me it seems like it uses quite a bit (much more then my brothers F8) So far I've seen about 500-600 balls per fill 48/300 tank. From what I've heard and seen, it seems like itís about average. (Bro's F8 will get about 700balls per 48/3000 tank) 8/10
Feed neck: Clamping feed neck is a little small for the Halo B loader. I had to sand down the halo b to make it fit. Now it does, it works flawlessly. To take it off it is a simple counter clockwise turn of the feed neck and itís off in a few rotations. It does its job 9.5/10
ASA: It works, I hate doing this, but in comparison to my brothers F8 it seems rather simplistic. It has an on/off switch...Great! But it doesn't tell you which way is on or off. The tank doesn't release pressure, so itís difficult to take off the tank under pressure. You turn off the air, shoot the gun, and it (the tank/A.S.A) still has pressure...so in that regards the A.S.A gets a 6.5/10.
Tools: From what I've taken apart all the tools are there necessary to pull the gun apart. It would be nice if they had a carrying case or something to hold everything. It also comes with a few o-rings if needed. 9/10
Rate of Fire: 17bps, isn't bad, I've used it a few times and was able to keep things within a 8inch radius from about 25ft. 9/10
Kickback: Very little 10/10
I would recommend this gun to any beginner or intermediate player who has done their research about paintball guns. It is much better than a bt-4 and a5 and does compete with the dangerous power F8. It is more reliable then the PMR. Not only is it accurate, its light, looks good, eyes seem to work well so far, simple bolt maintenance, and hasn't failed me yet.
