Yay. It's bloody amazing. Lost of mods you can do to get it just how you like it, really easy to clean, very accurate, and I have never has any failures of any kind. Plus, as mentioned above, it will take AR mags if you swap the magwell. And did I say it is non-restricted?
About customer service, parts will take a while to get here via Wolverine Supplies, but the good things is that it is very rare that you will need parts, in fact, I have never heard of anyone needing parts for it 'cos something has broke.
It's a tad front heavy, due to the heavy profile of the accurate target barrel, so that might be an issue if you have shoulder problems or something like that, but you can use a bipod with it, or get the barrel profiled to a G36 profile. Speaking of which, you can, for a pretty penny, dress it up to look very much like the G36, should that strike your fancy.
