I have a slightly used (6 months old) YHM Front Flip Sight Tower w/Bayonet Lug (YHM-9394). This replaces the front gas block. This is the flip up front site with bayonet lug for a .750 barrel. It has been to the range once, otherwise it has been mounted on a safe queen. No dings or scratches. There is some red loctite on it that can easily be removed. Great piece of gear, I am going a different direction with the project now.
SPF delivered. Thanks.
