Things I liked:I've been on the edge of PCPs and the CO2 conversion made the switch very easy to enter the AirForce world. Paintball tanks in either 12 or 20 work fine and the the accuracy and power are great for distances under 50 yards. I have a Leapers Bug Buster scope with the offset rings on top of the accessory rail and it has become my favorite air rifle. The trigger is fantastic and just a few steps below my IZZY match pistol allowing you to concentrate on the shot and not the creep. Pyramid took care of business in a top shelf way as usual and I will move into the high pressure air next. This rifle has no issues with pellet feeds and the loading is a breeze. I like the fact that I do not have problems loading JSB Predators or similar rounds. Things I would have changed:Would like to see someone like Hogue make a tactical grip for this like they do for the AR-15 also a tactical flashlight ring for the bottom rail. What others should know:If you are shooting in an urban setting as in a backyard or basement, the CO2 is the joint for NOT getting a call from your local authorities. DO NOT go outside in the ally or the street with this rifle. It is one badass looking piece and no one will believe you are not a sniper without some serious questions being asked. I use mine for target practice and urban rats when they decide to come around.
