Are you looking for local or mail order?
If it is mail order, the little 4x stright colt look a like scope with the BDC for 55gr bullets, or the rubber coated 3x9. TAPCO www.tapco.com for the low end, SWAFT riflescopes.com for the middle, and if you got the bucks www.valdada.com or www.sheperdscopes.com have scopes that cost more than some guns.
I had bought the Chinese made stright 4X with the 55gr bdc from Tapco and did not like it at all. I sold it to someone for half of what I paid for it and I felt like I had screwed them over. It was a real piece of junk.
I went with the see through carry handle mount and a regular 3 x 9 scope from wal-mart, worked much better for me.
