2K2 and Texas Storm Timmy's, Classic Intimidator, Matrix, Vikings, Angels, BKO's, and so many other markers there are too many to list.
I shoot a 2K2, Texas Storm and Ripper 2 Intimidators. I run a Halo or an Empire with a PMI Pure Energy Tank.
I recommend tossing a CP rail and a CP or Empire on/off ASA. I also recommend a CP two piece barrel on there.
Light, fast, efficient, easy to maintain, highly adaptable, quality!
Cost...but it's a sexy milled marker!
This is flat out the best marker I've shot in 10 years. The milling is equisite and enables the marker to shed weight from it's predecessors. Like intimidators it's efficient on gas, has beam break eyes and shoots ropes of paint. It comes stock with an Adj Ram Cap and clamping feedneck that securely holds my Reloader B without sanding. The milling is just amazing. I've never been so happy with a marker. The board is easily accessed through the LCD in the grip and adjustments are made through the membrane pad. The trigger guard has ample room for finger movements and the regs are top notch.
The annodizing can be a bit weak. The price is over $1600 but it's the best marker I've ever bought. If you can't afford it, spend $600 less on an Alias.
Best marker on the market, hands down. It's the marker all other markers will be compared to. Bob outdid himself. If there was a way to rate this higher than 10, I'd do so.
