Trijicon acog 4x32 scope - Trijicon ACOG 4x32 Scope w/TA51 Mount

The ACOG is amazingly clear and accurate. To fully appreciate the tritium illumination, you must spend some time in the dark, and it is worth it. The Bullet Drop Compensator is very sharp and well illuminated day or night, making it very easy to aim at distances up to 800 yards, much farther than I could ever hope to maintain accuracy. The housing is impressively sturdy, and although I don't plan to bang mine around, I am sure that if it was banged around, it would hold up to the abuse. It's built like a tank. I look forward to many years of use; well, at least for 14-15 years, which is when the tritium will need to be replaced. BUT, Trijicon reportedly takes care of that for you, as part of the maintenance. I imagine I'll be long gone before I'd need a second refill of this magical substance. ;-)
