It has the gas piston rather than the spring. Supposedly this offers more shot to shot consistency than springs. Barrels change out with an allen wrench. One .177 and one .22. The safety is like a Garand, in front of the trigger inside the guard; Similarities end there.
I first tried the 22 with Crosman 14.3g lead http://grabagun.com/crosman-air-guns-lh ... 2-500.html
It sounded a lot like a 22 so that may not be the perfect backyard caliber. From 20 or so yards it went through 3/8 plywood.
I used "Silent Cat: the Quiet Pellet"at 10.5g for the .177 barrel http://www.gamousa.com/reviews.aspx?productID=80 Not exactly silent but an attention-getting report.
