Awesome!! The ability to switch to Full-Auto instantly! You don't have to open the grip and hit switches like bushmaster or EM-1. This is a great marker for an intermediate to advanced player, I say this because of the care you have to put into maintaining this marker. The "low-profile" is a must have also, no hopper sticking out of your bunker. When you see my hopper, my barrel is right besides it and i'm firing at you. I play with the hopper attachment, so i'm not limited to 65 balls. You can even shoot at even upside down for about 5-6 shots because it's fed by the chain not gravity like most markers. I've also have not broken any balls using All-Star balls. This marker is very accurate and has long range.
It HATES liquid co2. CO2 Sucks with this marker unless you have an expansion chamber, anti-siphon on tank, and secondary regulator. Remote kit is a plus. Even running Nitro or Compressed air you should still have a secondary regulator. Don't use cheap paint! If you use good paint, you'll never break balls! Velocity adjustment is down barrel, if you have ball in the chamber, you must take barrel off to adjust velocity. No local vendors, you must purchase extra guide plates, oil, and regulator kit(when ordering minimum of $20) from ATS. Clips are pretty costly also, about $70, if you get a close range clip hit from a ball, you might get a crack. Very little aftermarket products. You can get a universal .45 grip and add a drop forward but what's about it. No barrels other than ATS manufacturers'.
The price is up there $500. But if you're looking for a mid-range marker, that's about the price of a bushmaster, autococker, spyder EM-1, or automag. This marker is great out of the box using compressed air, but, you should get a 2nd regulator. If you plan to run CO2, having a expansion chamber, 2nd reg, and anti-siphon will save you headaches from liquid freezing internal parts. A 12V viewloader is perfect accessory for the clip fed mags, no blank shots. It's low profile hopper is great for close courters. Because it's belt fed, you can shoot in awkward positions, even upsidedown (4-5 rounds). Extra Clips are very expensive $70. Order many guide plates, oil, and backup reg kit. I give it an 8 because you can't get the parts anywhere else but ATS. The service is also great! Rob Lussier at ATS is the GURU there.
