The older Japan built BSA scopes are much like the older Tascos, much loved, particularly the Platinums that have been used in BR competition. But....the newer BSA's have a checkered reputation, some love em, some hate em, just depends on the luck of the draw....BSA has wonderful customer service....and they need it...lots of returned scopes reported at RFC....some shooters don't even consider them good door stops with the their experience with them, others are repeat customers....I have had 2 BSA scopes experiences, the first was on a red dot that fogged up on me the first time I used it in damp weather, but for the $35 I paid for it, not a big deal. The next is a 3-12x42 airgun scope that's mounted on a Crosman 377, so far it's been an excellent scope for it's intended use, killing starlings and english sparrows in the back yard, along with a couple feral cats and a possum or 2....The scope is a bit critical on eye relief on 10x-12x, but it has worked well for about 300+ shots so far....Other than a few models that I have seen recommended a lot, I'd shy away from them in general, specially those low priced models under ~$75, there are much better optics out there for not much more money that have an excellent reputation.
