Well, Clay sent me a Jackson Hunter M54 to handle so here are my thoughts:
First the good: the rifle is awesome. I don't find it overly heavy. It balances nice and fits me well. Having relatively short arms the LOP, at 13.75", is a bit too long. The action is super smooth.
What I didn't like is minor. When free floating the barrel too much gap is left between the barrel and the stock for my liking. This is always a pet peeve of mine. The gap is even on both sides however, which is a good thing. I point this out because this is one of the first things I check on a rifle. The only other thing I don't like is the rear sling swivel isn't set quite deep enough in the stock but that's a minor issue.
These things are based on my opinion without having a scope attached or having the opportunity to shoot the rifle. I'll post those thoughts once mine arrives. Yes, I placed my order with Clay.
