well i ordered me a nice pdi 6.01 mm 554mm long barrel for my gspec. when i get the barrel i take my chamber apart and switch out barrels, at the time i had a firefly hard bucking that i used with laylax barrel and never had any problems with it. So i go out to shoot it, it was acting weird, for some reason the bbs weren't feeding from the mag. so i manually load 1 bb and shoot it and it shoots really quietly, i try a couple more shots and same deal. i know gspecs are really quiet but you could barely hear it shoot with the pdi barrel. so i disassemble it to see whats up and my bucking is completely torn. i know it wasn't from installing it wrong, all the notches line up and i never had a bucking problem the two thousand rounds i used the laylax barrel.
fast forward a bit, i got another firefly bucking and same deal, ruined another bucking. has anyone experienced something like this, suggestions??? thanks
