I have a echo1 m14 socom, I bought a 10 pack of king arms 110 round midcaps, didnt feed at all, so i have been trimming the bb catch to make them feed right, works great.
So i have been using the single shot mode
and my single shot started to crap out, is this a trigger contact issue? it feels like the piston is not making a full cycle.
also i installed a 509 mm 6.01 barrel, noticed a few bb's falling way short when firing on semi.....
