I bought a fairly cheap Simmons 3-9 x 50 to go with my AR15 back in '01 or whenever I bought it. For the price, it's been a really good scope. I spent about $75 on a 40mm obj. scope (don't remember the brand offhand, but not the same as my other one) for my Rem. 7615, and I think it totally sucks. I have to get at an exact position or I can't see anything through the scope. The 40mm obective doesn't pick up light like I need for post-dusk / pre-dawn shooting, and it has a hokey lighted dot which I don't need or even want. I've been looking at OpticsPlanet, and they don't really have them sorted any useful way for my search. Can I find a scope with >50mm objective lens? If not (and most likely NOT from my searches so far) what's a decent (read: under $500) light-gathering riflescope? Thanks!
