Yes Sir...you most certainly can with the dowel and sand paper...and that is the reccomended method. In the old days us Contendereons had but two choices in factory carbine barrels.... a 16.25" and a 21" barrel and both had the exact same diameter and taper...and same screw spacing. So we needed only one forearm. Of course there were all sorts of custom, after market options in barrels and forearms, but that's a whole 'nother story. But you know people just can't stand success....so, what does TC do??? Well, they start by burning down the factory(I ain't kidding ...but I don't think that was part of the original plan), coming out with a new and "better" gun and a big 'ol heavy 23" bull barrel for it. Yuck!!!!...I really wouldn't have minded tooo much, but they also disscontinued the 16 and 21 and this 'ol man was sick
. So now, according to some, it takes two forearms to do the trick with all available factory barrels, but, actually you can modify your forend as you said, to fit the bigger barrel and simply utilize some magic spacers(Keith can tell you about them)and still do quite nicely with just one foerarm
