Not to be a Buzz Killington, but I owned a BSA once - for 48 hours! Returned it for a full refund - thank god.
I owned a second one for about 30 minutes. I drove home with the gun, tore the scope off, and threw it in the trash.
I'm just sayin'...
I can't recommend you spend your hard-earned money on one. There are a LOT of low-dough scopes on the market - I don't think you have to stoop that low.
Literally I have a hand full of low priced used scopes in my basement that I would love to get rid of. For a 17 HMR, you could use a 4x fixed scope and be fine for all distances you will be tempted to shoot. However, if you wish to spend some money, a good quality scope is worth it, since that may be one of the most accurate rifles you own. I am constantly impressed with the fact that my .17 HMR and my .22 WMR are so accurate. I can do a 10-shot ragged hole with my WMR at 100 yards, and my HMR is not far behind.
They don't have a ton of knockdown power, but the squirrel does not know what hit it below the ear!
I was looking at one last night that was designed for the .17, and it actually had a ballistic compensator. I can't remember the manufacturer right now, but it was VERY sweet. I will ask my fr in law if he remembers - he was looking at it with me. I believe it was under $200.
