I would run away fast from the BSA and Tasco (actually I think the early post had it right at Trashco).

I have a BSA red dot scope on a Colt Anaconda 44mag. When the zero stays put you can hit with it, but who wants to re-zero every 200 rounds or less. I plan to replace it with a Aimpoint. Also had several Tasco' s that did not survive very lond on Crossman air guns.( Yes they were made for air rifles.)

If money is tight I would consider the following:Prices from Midway cat#191
Leupold VX-I 2-7x33-------------$179.99
Weaver V10 2-10x38-------------$171.25

Strong high quality glass is even more important on hard kicking rifles (and handguns as I found out the hard way) especially .300 win mag and up.

While were talking about scopes, don' t buy cheap bases or rings either.
Use blue locktite on base screws.
