Get the xm8 or m4. Im almost a 2nd luitenant and ive tested every gun closely. Scar light only has 5 accurate bullets in its spray then its all up to luck. Pistols arent necesarry if your using a good enough gun to not have to switch to pistol for the kill. M4a1 all its bullets go near the target so its a great choice and one of the best spras weps. Xm8 is great because about 7 bullets go in the right spot. The scope is good for 1 or 2 bullet bursts and is easy for hs's so if your not good with hs's its also good for spray if your close enough. Both xm8 and m4 are good close mid and long range so their good choices.
