My first was a 10/22.I've had it 20yrs now.I put a cheapo Tasco on shortly after I bought it.Not very clear or sharp but it shoots surprisingly well with it.Summer shooting caused the turret caps to expand and they're lost now plus both ends need to be re-tightened regularly.I could just apply some lock tite but my old friend deserves something better.I think you'll soon come to the same conclusion with the BSA.
Enjoy!!!!
