Assembled an H&R 20 ga slug gun. For those familiar with the H&R Ultra Slug Hunter (USH) slug guns this one is not a heavy bull barrel. It is a fully rifled Tracker II barrel which is slightly heavier than a standard barrel. It came with sights, had a smith d&t for a scope base. Fit the barrel to an SB2 frame. Added camo synthetic stocks and a camo Nikon scope. Due to the light weight compared to a USH, I added a 14 oz mercury recoil reducer to the stock. should be a nice shooter.
