I am far from an expert on these things hence the question, but. I realize they are made at the same factory. If a camo forend that fits a standard taper barrel will also fit a factory (available from TC or retailers without special order) heavy taper barrel why will my forend not fit the Fox Ridge heavy barrel? When you buy a FR heavy barrel you have to buy a special forend. I know the factory camo forend will fit both the standard taper and factory available heavy taper barrels, but not the FR heavy barrels. This is irreputable evidence that there has to be some difference in the dimensions of a factory heavy taper and a Fox Ridge heavy taper barrel. My question remains what is the difference in the two; lets say a .300 win mag bought from Cabelas and a .300 win mag bought from Fox Ridge?
