m28 m24 echo1

I have been sniping for like 2 years and have used Echo1 guns mostly,but my m28 is my fav. Anyway I am looking to upgrade my m28 what should I use?:shrug:

last week i was playing a game with some friends, when my m28 started slam firing. so i took it home, test fired it again and it stopped slam firing. all the sears are intact as well, so i have no clue what the problem could be. any ideas?
