I just received my Buffalo Carbine back from H&R after having a 22 Hornet and a 20 Gauge Vent Rib barrel fitted. The barrels are fine, but I wasn't very happy with the way the rifle was packaged when I got it back. the shotgun barrel was on the frame with the BC foerend stuck on it (the forend is too small for that barrel by quite a bit so it would not draw up against the barrel) and the 22 Hornet barrel was in a box that was thrown in loose with the gun. The sight on the Hornet barrel went through the box the barrel was in and though the outside box and was nearly knocked off the barrel - one ear was smacked pretty hard, damaging the sight. I did call Remington to let them know and talked to Greg, who was having computer trouble and could not be of much help in the time I had, so I ended up sending him an email yesterday. I'll see what I find out later when (or if) I hear back. Has anyone else had these kind of problems when having a barrel fit? Other than that, I think I'm going to really like the Hornet barrel on the carbine and am seriously thinking about reaming it out to a K Hornet.
