Thoughts on forearm hanger bar systems.(Bullberry's, MGM) Is it worth the hassle and expence. Is it that much more accurate.

I like them and most of my TC stuff is set up with hanger bars. If you are unsure about it ....purchase the custom barrel without, shoot it and decide if you would expect more accuracy for the added expense. Figure a hanger bar will cost you around $18-20, fore end set up for a bar cost you at least $50-70 and go from there.
