Nice one Shay . there was a few niggly things that I wasn't happy about with the gun mate, one was the problem with the barrel being loose, the other was the Barrel shroud which was held on with two AF grub screws which just wouldn't tighten up enough, I finally removed the shroud and Tapped out the holes to 4mm and fitted a couple of larger grubs! I also slid some 13mm O Rings down the barrel to support it where the silencer adaptor is fitted, the adapator actually slides over the end of the barrel and threads internaly into the shroud which was a bit crap, the O Rings help support the unit
