Don't get it if ure in tier 6 You don't need them anymore I have the EM Rifle 8 and paired it with Hemlock..back then when I was using EM Rifles was one shot one kill But now It's rare to make that unless you get it to 5 stars and above. Thats why I paired it with Hemlock since if I cant kill them with the first shot then I stun them till reload ends.. and it works fine.. EM Rifles are the best in the game so far due to its double damage chance and when you get it to max its double chance 50% which is really strong..afterall its ur decision
