Managed to have a quick mess about with it while the baby had a nap! Really impressed with it so far, hope to give it an fielding at Leicester Gaol on the 11th.
Just googling for minor upgrades at the moment like hop rubbers and H plates etc!
Small edit,
I did notice that the loading nozzle gets stuck a little. I can pull the charging handle bit back and when I let go it needs a gentle tap to get it fully home. I assume it may stop doing so when I've put a few mags through it.
Anyone had a similar issue?
