The BSA Supersport is an air rifle produced by BSA Guns (UK) Limited a subsidiary of Spanish manufacturer Gamo. It is essentially the same rifle as the Lightning, the only difference being that the Lightning has the BSA Volumetric Silencer fitted. It is made in three calibres, 0.177 in (4.5 mm), 0.22 in (5.6 mm) and 0.25 in (6.4 mm). It comes with a simple post and notch plastic sights. The Supersport was first introduced in 1986. There are two versions - the Mk2 version differing in that it has three cocking links, unlike the older two links - and there is now an external spring guide.
