Encores are not all that hard to find on shelves, let alone order. Granted most States require an FFL because of the ability to change barrels. I hope you did not pay anything down on the rifle before the order. Because if it was me, and I had not received it yet, I'd be telling them I would go somewhere else... That just sounds like an extremely long time. I wonder if they are waiting to make sure they get a certain sized order or something before they call Thompson Center so they get better rates...

Out of curiosity, call Thompson Center on Monday and ask them what is holding the order up and see what they have to say. It sounds more to me like you're being jerked around.
