Bought this a while ago and just never actually used it, now I'm having a clear out so it can go. I test fired it when I got it and it worked fine but I haven't got any gas in the house to re-test it so not sure if it still will but it should, it's only had half a mag through it. It comes with slightly better than stock sights, the fibre optic just needs installing in the front. Has quite a nice weight when it's got a mag in, with the metal slide and mag. Comes with all the backstraps, 3 extended grip panels for longer mags, a few random accessories and 1 short mag. Price includes postage.
