Matt the musket is the biggest cheater of them all and a proper dirty player. Myself and a few mates had the misfortune of playing at a site the same day that guy did. Disgusting player, not mentioned the site but he got a month ban for his game play that day. he's also posted a frag video which shows him killing like 15 people with it which is absolute BS. his frag killed two people the rest had been shot on the right flank.
If no one else has seen this it's worth a watch and a listen to. This was sent to me after the incident mentioned about.
