Frequently Asked Questions

What makes the Trijicon ACOG TA31 a good choice for a 'one optic for life' scenario?

The Trijicon ACOG TA31 is highly regarded for its extreme durability, functioning as a 'tank' that can withstand harsh conditions. It's a prism optic, meaning it doesn't require batteries and is powered by ambient light, ensuring reliability. The integrated Bullet Drop Compensator (BDC) reticle also aids in accurate shooting at various distances.

How does the Bullet Drop Compensator (BDC) on the Trijicon ACOG TA31 work?

The chevron reticle on the ACOG TA31 serves as a BDC. The tip of the chevron is the 100-meter aim point, the nook below it is for 200 meters, and the tip of the post is for 300 meters. Further markings extend for longer ranges, and the chevron's width at 300m can estimate target size.

What are the advantages of mounting a Trijicon RMR on top of an ACOG TA31?

Mounting a Trijicon RMR on an ACOG TA31 provides a secondary aiming solution ideal for close-quarters combat (CQB). This allows for rapid target acquisition at close range, complementing the ACOG's primary function for mid-to-long range engagements, offering a versatile two-optic system.

What is the main disadvantage of using the Trijicon ACOG TA31, especially with an RMR?

The primary disadvantage of the Trijicon ACOG TA31, particularly when paired with an RMR, is its performance under night vision conditions. Users may experience issues with eye relief when trying to use night vision devices with this optic setup, making it less ideal for dedicated night operations.
