BSA Essential 551 3:9:40 scope

I own 4 of the Essential series scopes, the 3-9 sits on a 350RWS, a hard shooter that killed the RWS branded scope supplied with the gun in less than 30 shots. A 3-12 sits on another magnum 460 with no problems as yet, and a pair of 4x on lesser spring guns. I DO believe in one-piece mounts and use them on all my air rifle scopes.
Now,, I don't shoot thousands of pellets a year so my reviews may be considered jaded, but I can't say anything bad with any of my BSA Essentials, and the warranty offered isn't all that bad either.
Had an experience with a BSA Contender that was over 10 years old, it moved from gun to gun, firearm and airgun both, an internal adjustment gave out. I made a phone call, didn't have my original bill of sale.......cost me postage and $10 for a new 3-12 Contender (which still sits in its' box due the tactical style of reticle) but overall good warranty experience.
