I recieved my x25 about three weeks ago and mine too came with a 12" barrel, but it is very accurate. It shoots very smoothly, and is a sinch to field strip. And not to say but this marker looks cool as all hell. Everyone thats seen it were in aw,
The only thing bad about the marker is the costomer service from the company. I got my gun 3 weeks ago and have been emailing them and calling them the the hole 3 weeks questioning why i got a 12" barrel instead of the 14" x-barrel, and mine came with NO parts manuel or anything. And i have yet to hear a word from them.
in conclusion this is a great marker,looks cool, shoots smooth, very accurate,ease of cleaning. The ONLY reason i did not give it a 10 is because of the costomer service from the company.
