Trijicon AC11031 4x32 ACOG Objective Flip Cap TA91 killFLASH Required AC11031 UPC 719307311152
Product Description
The Trijicon 4x32 ACOG Objective Flip Cap (MPN: AC11031) is a heavy-duty tactical lens protection cover engineered specifically for Trijicon 4x32 ACOG optical sight series. Designed to protect the objective front glass lens from scratches, dust, water, mud, and impact damage during transit, field carry, and harsh tactical operations, this flip cover ensures your primary optic maintains pristine clarity when brought into staging.
Precision-molded in the USA from durable, chemical-resistant matte black polymer, the AC11031 features a spring-loaded snap-fit hinge mechanism that allows rapid, silent one-handed deployment. When snapped open, the cap stays securely locked back out of the shooter's line of sight to prevent target obstruction or distraction during fast-moving shooting schedules.
Important Mounting Requirement: The AC11031 objective flip cap is designed specifically to slip onto the outer housing ring of the Trijicon TA91 Tenebraex killFLASH® Anti-Reflection Device (ARD). Therefore, a TA91 killFLASH must be installed on your 4x32 ACOG objective housing prior to mounting this flip cap. Backed by Trijicon's legendary reputation for combat-proven durability, it is an essential accessory for military, law enforcement, and civilian ACOG owners.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits all standard Trijicon 4x32 ACOG models (e.g., TA01, TA31, TA110 series) equipped w/ a TA91 Tenebraex killFLASH Anti-Reflection Device installed. (Note: REQUIRES a TA91 killFLASH ARD on the 4x32 ACOG to thread/slip onto; will NOT mount directly to bare 4x32 ACOG objective housings without the TA91 killFLASH in place).
- Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually/physically inspect the chamber to verify zero live rounds are present.
- Ensure your Trijicon 4x32 ACOG has a TA91 killFLASH Anti-Reflection Device securely threaded/seated into the objective lens housing.
- Clean and degrease the outer ring of the TA91 killFLASH using isopropyl alcohol.
- Align the Trijicon AC11031 flip cap housing with the front profile of the TA91 killFLASH.
- Push the flip cap housing firmly back onto the killFLASH bezel until it seats completely flush w/ zero friction gap.
- Test the spring hinge mechanism by pressing the lock tab to ensure smooth, immediate spring-action flip-open movement.
