smellaard Posted June 12, 2016 Share Posted June 12, 2016 I bought a g&g cm16 srxl played with it for two times. first time it was ok to use at the site site limit is 350fps second time different site but same organisation and same site limit 350 fps but my gun was today at 417fps so now i'm not sure what to believe or do!!! did they let me play first time even I had high fps or has my gun upgraded it self do I need to change the spring? is this something you can do yourself? also not sure what standard spring size is in the gun telford area Link to comment Share on other sites More sharing options...
Supporters Sitting Duck Posted June 12, 2016 Supporters Share Posted June 12, 2016 their chrono is f*cked or you using 0.12's in my book sites will ask you weight of bb - often 0.20's are used sites like Mall chrono the gun on THEIR mags or on pistols they fire a few shots out then refill the mag with THEIR 0.20's This ensures all guns are checked as thoroughly as possible to ensure they are with site limits No a gun will not increase fps - normally this will decrease over time as spring fades & seals wear There could have been a mediocre seal with nozzle to hop that may increase decrease with say different mags or iffy seal that may have improved - or hop fully wound on/off may alter the fps But 67fps variation and UPWARDS ???? look at you gun's box - if you got an import say destined for USA - it would normally have a yellow "high velocity" sticker on it - 390/400fps But most normal G&G's shoot at 330-ish - some a little over but not THAT much you sure you haven't dropped in 0.12gm bb's - coz that would probably be about right to me Link to comment Share on other sites More sharing options...

Seems unlikely for a cm16 though. Link to comment Share on other sites More sharing options...
