just as the title states, Im selling my 1 piece Stiffi barrel. it has a bore size of 0.691. the inside is in excellent condition with no scratches. the outside has normal wear on it...but it is minimal at most. the small wear on the outside has no affect on the performance of this barrel. you can ask anyone, I baby all my gear.

1 piece Stiffi barrel .691 bore size = $75obo
