He cannot give us a current range report, as one of the most vindictive things about C-68 and it's updates is that owners of such pieces are no longer legally allowed to take these out to the range to fire them (as of 2005). There might be exceptions for cops, but not for the rest of us.
Of course, I'm sure people use their own legally bought and paid for property anyway, they just won't publically admit it
As for me, I had one built in 2002. It had shot 3 to 3.5 inch groups at 100M, iron sights, tight sling used. Was good enough to place on some occasions, and even win a local service rifle match prior to the above date.
Sorry about the potential hijack,

but I just had to mention the C-68 stuff
