REVIEW BY: Rev. Bryan A. Hussey Friday, February 26, 2010
I've got this wonderful little scope mounted on my 1983 Marlin 60, and it works great! For a plinker scope, it holds it's zero very well, even after a few hundred rounds it hasn't moved. Usually I write off BSA, but I'm very impressed with this one!

A fantatstic little rimfire scope way better than you would expect for its low price. Fitted straight onto my stainless Marlin 60 and looked great. I was able to zero it really quickly just by watching where the bullets kicked up the dust through the scope while aiming at a small rock. Quite a few clicks on the adjusters were needed, one click is a very fine adjustment, but in no time the little rock was blown to pieces. Fired another 30 shots or so at other twigs and stones, this is a very accurate little setup it would be lethal on squirrels, rabbits etc. It was much easier to zero than I anticipated and has a really clear sight picture, I look forward to trying it on a paper target at the range. What's not to like?
