About 15 years ago I owned a Crosman American Classic .177, did some mods like smoothing the trigger and aftermarket sight sold by Crosman but don't see them offered now. I was an IHMSA shooter in the 80's in upstate NY so naturally when I got my airgun I purchased little steel animals. The backyard was big enough I could shoot them at correct distances. That gun could shoot, I once shot a group you could cover with a dime. When we moved the HOA had a rule about airguns so I sold everything, now I find out their rules are unenforceable so I purchased a new American Classic. I see Crosman offers a steel breech and sight, don't remember my first gun had a steel breech so I'm wondering if the purchase of one now is worth it? I believe the aftermarket sight back 15 years had micro adjustment not like the one offered today. Can't remember the manufacturer of that sight but it was used in competition on big guns back in the day. Anyway I enjoy target shooting in my back yard and with big bore ammo in short supply pellets are fun to shoot. I'm retired now and have plenty of time to practice.
