I highley reccomend using the M24 over the M24 and CZ50. The M24 and the DMR fire the same calibre but I like bolt action rifles compared to semi automatic. I wish they would fix the loading physics when it came to the M24 and other rifles, cause comes on Im not going to wack the upper side after putting a 5 round mag in. M107 Is great! nice 50 cal round! 1 shot wonder I like to call it:angel: theres 2 advanteges it has over the other rifles is. 1 shot kill, rounds are easier to find. Disadvantages are it makes a hell of sound and attracts zombies like a plague lol. But having said that if your a kean Sniper like myself you will be sitting far away and concealed and only take 1 shot anymore and your position is gone. Thats a general thumb rule for anyone. Anyway, Hope this helps mate :blush:
