i agree with j7.. certian guns i wont clean every single outing, that is due to amount of shots fired, the gun itself, ect...

precision weapons, i clean them every outing, right after i get home...

if you dont regularly clean your guns, you can get build up that can cause serious issues down the road... ive seen guys that dont clean their guns, chamber rounds and when they started turning the bolt down the gun went off, because there was crap in the area where the round is and wouldnt seat correctly, pressing it against the bolt, and gunk on the pin itself... not safe at all...
