Moved house a few weeks ago and eventually got around to looking to see whatever crap the previous owners had left me in the loft. After squeezing through the unnaturally small gap I discovered, right by the hatch, in a cover with a tin of pellets, one of these . . A BSA Supersport. Although the muzzle end is different and looking on google it's some type of muzzlebrake??? Not sure exactly what model it is as the mount sits right over the full description. I can't bring it down for a closer look as I don't want my kids to see it yet. I can also make out in the description the figures 8A?? It also has an Apollo scope fitted to it. Have I proffed anything half-decent or just cheap tat?
