Gbb scar we

[Chandler]

alright lads, not sure if this has been covered before..
but my problem is this..

whilst shooting most bb's fly straight, then the occasional once will just ski jump off the radar ( i'v purchased a WA tech hop which apparently is much better, just waiting for delivery )

whilst shooting sometimes the valve striker doesent come back far enough.. this just gives a small fart from the gun rather than putting any power out? i think its down to the bolt not cycling properly, asif there isent enough gas in? the mags are full.. tried Co2 and Propane..
Brought a new valve striker but havent fitted it yet..

The gun is nice and lubed so i dident think i'd have a problem.. Other than that the range is immense!

thanks,
chandler
