What is it you want to do? What is the goal/purpose of the optic?1x scopes/dots for cqb1-4x scopes for cqb and dsm4x or more for a varmint gun perhapsFigure what you want the optic to do then maybe narrow your price range to "under $1200" or "under $500" or under $250 - then we can give you an opinion to a better question like "What is the best 1-4x scope for my AR under $250?"
+1 on Zona's advice...Figure out what you want out of an optic... a $2500 scope is great but if you want it for close up work, it's just a club.I myself, since I only have 1 EBR, (Evil Black Rifle ) opted to get a 1-4x optic with an illuminated reticle. Gives me options for CQB and for some longer range fun when I want to, works in the dark with a light for CQB, etc... Your needs may be different, and you may want to try out some different optics on guns to see what you really want. Brian
What length is your barrel?What configuration is your AR? A2, A3, A4?
If your rich, the ACOG is a nice way to go. I like EOTech. GG&G is selling the 512 for around $410 and it comes with a quick detach mount and lens covers.http://www.gggaz.com/
lm45 - which one do you have?
+1And it would help to know if you wear glasses or contacts and wether or not you intend to wear them when you look through the optic.
Your always god for a laugh.Adios,TG
