Thanks for the replies everyone. It's been a while since I've revisited this thread and it's grown a bit.
I haven't had a chance to shoot the rifle as much as I'd like to but I did manage to take it out to 200 yards a few weeks ago. The little 18" barrel is a real shooter. I've been quite impressed with it. My reservations about the short barrel have long since been laid to rest.
The barrel is a 1:8 twist and the trigger is the Rock River 2 Stage "Match". It feels good and I like it but I have to admit that it has taken some getting used to.
Here is an honest 200 yard bench group shooting the 60gr V-Max Molly.
Here is a 110 yard off hand one shot group. This is the type of accuracy I was hoping for.
I know it's a very trivial detail but I love the fact that the entire rifle fits into a compact take down shotgun case.
