Hey all I received my TC walnut stock and forearm today that I ordered off of Ebay. The seller said it came off of his pro hunter barrel. After I removed my flex tech forearm I tried to put my new one on my Katahdin pro hunter barrel and it doesn't fit quite right. I think that the screw hole in the new forearm is recessed deeper because when I tighten the screws the fore arm will still move up and down. Maybe i could put a few washers on the screws to shorten them up? Do i need to buy new screws? The screws I have now are both the same length. Any help is appreciated.
