Fantastic glass - Trijicon 4x32 ACOG Scope M4A1 Rifle Scope w/ Amber Center Illumination

The glass is outstanding and the Trijicon TA01-NSN housing is basically bomb-proof. This is a good match for front sight base carbines. The eye relief is tight, but if you shoot nose to charging handle, you will not have any problems. Your cross hairs will fade against a dark background when going from light to dark.
