I ended up buying one of these at Oklahoma Dday- after the first mingame I realised my timmy was going to hate this paint all week long.
the marker itself, internally, at least, is little more than a 98 custom. It shares a lot of similarities with the alpha black line as well- the magazine/tool kit and Milsim styling both are pretty much dead giveaways. Stripping it down can be a bear, be warned- it kept the clamshell design of most tippmanns, and with the stock and shroud that's kind of irritating to remove.
It shoots.... well, like a tippmann. It's not particularly good, but it could be worse. It's OK for air efficency, though far from great- I shot about two cases at Dday and didn't have to fill my air tank more than twice, but I also have a big honking air tank.
In as far as problems go, it doesn't come stock with a cyclone, that's a big downer. that said, it is really easy to put an aftermarket cyclone on it- it comes pre-drilled for one, so all you do is attach the fittings and you're good to go. The stock barrel is meh, but that's not saying much, since most tippmann stock barrels are meh.
Externally, it's pretty good looking- it has a large US army jewel logo on the left side of the body, and a nice flat black powdercoat job. The stock is really good looking, if not that durable feeling- in other words, all you service people, when you go prone, don't break your fall with this stock!
Overall, I feel like it's another aesthetic option for those who want milsim gear from big box stores, and a cheap nice backup for mil-sim and woods players who need a cheap backup. The mil-sim addons are nice, and let you play with it stock out of the box without it feeling incomplete somehow. All in all, I'd recommend it for new players and people who need a Milsim backup without dropping a lot of cash.
