Ty's Review of Trijicon TA31RCO-A4CP ACOG 4x32 USMC Rifle Combat Optical Sight for A4 w/ TA51 Mount

This the exact model RCO I used in Afghanistan. Perfect for finishing out my M16A4 clone build. Good 4x and it's always illuminated since it's got the tritium and fiver optic. The BDC reticle holds pretty close too.
