Nice. I picked up one blind, and it is VERY smooth. I like the way the carbon fiber barrel matches with the body milling. Make sure you have a fresh battery. That is the #1 issue with Excaliburs since they run two solenoids. Link us to your review when you have time to post it. Welcome to the AKA family.
For those not yet in the family, you can't buy a better marker for the price. You can pick up an '03 Viking for $450 or so. You should be able to launch nearly a full case off one 68/45 fill, and there are only about two markers out there that are faster. AC-threaded barrels are used, so finding barrels is easy. The Javelin is quite good, but if you want a barrel kit, they are readily available.
