Hi all,

So, I'm in the middle of an AR build-- rifle length, 20" threaded barrel. I plan to sight it in at 100 yards. I had heard so much about the vaunted ACOG by Trijicon that I started seriously looking into it. Then I saw the price tag-- YIKES! Those buggers cost MORE than the rifle itself!

So, I'm wondering if someone makes a less-expensive alternative, using similar principles, such as using a fiber optic coil to collect light, instead of using a battery. I'm probably looking at 3x-4x magnification. To be fair, I'm not going to get my hopes up-- I'm sure there's good reason a genuine ACOG costs so much (hopefully they aren't like Nike and charge double what it's worth simply because of the popularity of the brand), but if anybody has a recommendation, I'm all ears!
