I've been doing some of the suggestions, that the more experienced air soft Snipers have been posting, about polishing barrels, washing BBs. Going to a slightly heavier BB,wrapping the inner barrel with teflon tape in efforts to improve accuracy a bit more. All of these helped and made a noticeable change in the further distance accuracy. I've been shooting at a telephone pole that is 175'-190' maybe further but, I'm being realistic. the accuracy tightened up. Instead of hit and miss I was able to put 3 follow up shots after the first, after washing the bbs I did need to readjust the hop-up backing it off just a little, and they started to get consistant the hop-up was more sensitive. Right now I'm happy with the fps. Thanks:cheers:
