An update on use after a couple more events .
a month ago I used it in minus 3C and incredibly it emptied every mag , every time which was a shock having had earlier VFC rifles and it also having such a large bolt . Especially on only green gas and not red or black
I used it again this weekend and this time it was a little warmer . I had also fitted the adjustable valve so I was using it as a battle rifle with slim fore-end and iron sights instead of as a dmr .
Range was still amazing with airsoft surgeon 0.3g BBs with no loss of range with the drop in power created by the adjustable valve . The hop has bedded in now and accuracy was nothing short of astounding to the point I was quite easily picking out parts of bodies behind cover at 60-70M . Mag changes are getting smoother too.
As an aside , I had also fitted the selector from a real G3 and that worked flawlessly on all modes with no modification or tooling . Literally a drop in fit
