Do not, under any circumstance, buy a BSA scope. Ever. Their quality is abysmal and their customer service is worse. I bought this scope in Jan 2009 and it broke in July 2009 after less than 200 rounds of .223 being shot. I sent it back for warranty service and am now being told that I won't have it back until December. For comparison, the industry standard is 10-14 days. I wish I could post the email exchanges I've had between them so you could really experience their "customer service" firsthand. If you're still thinking about buying a BSA, go to one of the shooting enthusiast discussion boards such as TheHighRoad.org and search BSA. You'll find the comments run about 10:1 against. Do as I should have done and buy a quality scope from Leupold, Nikon, etc. BSA is JUNK.
Pros: none
Cons: poor quality, abysmal customer service
