Great design... poor construction - TruGlo Tru Bead Turkey Universal Dual Color Sight

The price was worth it for the front fiber optic sight post but that is about it. The rear sight has too few threads to securely mount to rib of shotgun barrel. I'll be filling in the gaps with an adhesive to ensure the rear sight doesn't fall off from recoil. The screw used to hold peep sight or U sight in place came overly tightened and stripped when I swapped the sights out. The peep sight is too large to be effectively used for accurate shooting. The peep sight also did not fit securely in the groove for rear sight so it would twist slightly side to side. It was a great idea to have interchangeable and adjustable rear sight but quality of construction does not look like it will hold up to shotgun recoil.
