I'm sorry, but thats a lie! XD Although it did happen to my crappy P90 that was an LPEG (30 dollars, didn't care about it) It does NOT decrease accuracy, [high quality silencers don't have an inner barrel. the crappy p90 did so it was basically like having two barrels. Good ones (which are the expensive/seperately bought ones) are just open and will not mess it up] And accuracy/power/malfunction like I said won't mess up it unless its a seperate barrel. Which is only found on crappy LPEGs. And Spartan270s right about the bbs. use .2s and higher, but not using crappy BBs is another important factor. Don't buy em from sports authority, buy em from a trusted site. Good brands are Excel, marui, KSC, maruzen. [examples]
