I am in the market for a .22 tactical rifle. There are so many options out there, I need help deciding! I am torn between the GSG MP522 and the H&K MP5 by Walther. Both are around the same price range. After reading on the internet I have noticed that a lot of folks are having problems with the GSG because of jams and the H&K may be so new that there aren't too many opinions yet. Now I am considering just waiting and saving up about 100 more bucks and getting the Sig Sauer 522!!! I already have a 10-22 and want to keep that the way it is, I realize that I could trick my Ruger out for not too much money, but I and bound and determined to get another .22. Please help with my decision!! factors are reliability, cost, longevity, accuracy and overall quality!
