good post mate
ive often wondered this myself and different people say different things about different guns. i fitted a silencer to my daystate merlyn and it made no odds at all to the groups at any range with any pellet. that gun just seems to land them where you point them, provided you have some decent glass on the top and know what you're doing.
on the subject ive just bought a mk4, not even fired it yet
and most people ive seen with mk4's have silencers on them but cant tell me if it improves it or not, they just say they like silencers? if anyone can save me time and help me with some rational reasons it would be nice
