Trijicon ACOG TA01NSN 4x32 Scope
Period 1990s. TA01NSN: Trijicon ACOG 4x32 Scope with Amber Center Illumination for M4A1 – includes Flat Top Adapter, Backup Iron Sights and Dust Cover. Included in photos is a Tenebraex killFLASH.
Designed to the exact specifications of the US Special Operations Command for use by elite US forces, the Trijicon ACOG TA01NSN is Trijicon’s most popular ACOG. The ranging reticle allows for bullet drop compensation out to 600 meters without any manual adjustments. The reticle will appear black during the daytime and will glow amber in the dark, thanks to Trijicon’s patented tritium illumination. The TA01NSN features built in backup iron sights, thumbscrew Picatinny rail mount, and does not require batteries to operate.

Trijicon ACOG TA01NSN 4x32 Scope with TASCO OPTIMA 2000 Red Dot Sight
Period 1990s. This setup was first seen on M4s in use by US SOF troops in the 1990s. The rear backup iron sight of the ACOG is replaced with a TASCO Optima 2000 red dot optic. This setup combined the benefits of a magnified optic and a parallax free non-magnified red dot optic. Users could accurately engage targets from close to medium ranges.

TASCO OPTIMA 2000 Red Dot Sight: Measuring 42mm x 25.4mm x 23mm, it was the smallest and lightest red dot sight in the 1990s. It was primarily used on handguns, but later adopted for use on rifles, or installed onto magnified scopes with adapters made by companies such as Knights Armament Company (KAC). The Optima 2000 has an illuminated red dot aiming dot powered by a CR2032 battery. It automatically adjusts the dot brightness to suit the shooting environment, allowing clear parallax free non-magnified aiming. It features 5000g of recoil resistance, and has earned solid reputation at battle fields of Afghanistan and Iraq.
