I'm thinking about picking up one of the new breed of "tactical" .22 LR rifles. I was considering the HK416: and the SIG 522: A friend of mine is going to grab a Ruger SR-22 at the next show, but I already have a 10/22. I was leaning towards the H&K, but look what just came out: the ISSC Mk22, which is a virtual clone of the FN SCAR in .22 LR. Tacticooly, this one pegs the needle. Opinions?
