Following the acquisition of Beeman Airguns by SR Industries, the rifles were marketed in the USA as the Marksman 60 and Marksman 61.

Since its inception in 1984, the HW 77 has been the subject of numerous minor improvements and upgrades. HW 77 models are frequently classed into three progressive 'Marks' by owners and enthusiasts; however, these classifications are not officially used by Weihrauch.
