G&g m14 ebr up for sale, when I bought this gun it was barely reaching 230 fps on .28, so I got to work on it, the cylinder head was pretty much fucked and compression was non existing, so I replaced the cylinder head and at the same time I replaced the piston with a shs 14 metal tooth one and piston head oring , replaced the motor with a higher torque one that I had here laying around , and new 110 spring gave it a service and now it shoots really nice at about in the 290 to 295 fps on .28 ........this is where you would love or hate it..... but I've shortened by a foot making it great for cqb, re- tappet the outer to 14mm cc so that I can put a tracer unit or silencer, this m14 journey with me has now come to an end and she's up for grabs at £275 post and PayPal or trade, im after a hpa engine what have you got?
