Round knobs looks nice. Nothing screams 1970's like a white line recoil pad. Grab your polyester bell bottom pants, with a nice wide white belt, and buggy on over to the Skeet field. People laugh when I tell them I hate fitting fore ends and would rather do three butt stocks than a single fore end.There is no hiding a mistake on a fore end and there can be many times more surfaces needing to be fit at the same time.
