Trijicon ACOG TA01 Tritium Scope 4x32 w/3.25 MOA Type 2 RMR

ACOG TA01 Scope: Combat-Proven Fixed 4X Scope Excellence

The Trijicon ACOG TA01Tritium Scope 4x32 w/3.25 MOA Type 2 RMR delivers combat-proven reliability when precision matters most. Special Operations forces chose this ACOG TA01 scope because it survives direct enemy fire while maintaining zero. This fixed 4x scope offers perfect magnification for tactical professionals, ranging from 25 to 400 yards. The tritium amber crosshair eliminates battery dependence and automatically adjusts brightness.

At Proven Optic, every purchase supports advancing justice through Proven Justice. This battle-tested ACOG TA01 scope offers superior durability with fewer moving parts than variable alternatives. Backed by our 90-day return policy and price match guarantee, this fixed 4x scope delivers precision that tactical professionals and hunters trust.

The ACOG TA01 scope excels for military, law enforcement, and Special Operations veterans who demand uncompromising reliability. Experienced shooters appreciate this fixed 4x scope's battle-proven durability and tritium illumination that never fails. Tactical hunters, competition shooters using 3-gun formats, and serious enthusiasts who value precision over 25-400 yard engagements find the ACOG's legendary glass clarity and 36.8-foot field of view ideal for rapid target acquisition.

New shooters may struggle with the ACOG's 1.5-inch eye relief, requiring extensive training to master proper positioning. Budget-minded buyers will find better value in modern LPVOs that offer variable magnification at lower costs. Hunters requiring magnification beyond 4x for long-range shots, competitive shooters needing ultra-precise reticle adjustments, or those who prefer simpler maintenance will benefit from traditional hunting scopes or red-dot alternatives.

Battery-free tritium illumination keeps the ACOG TA01 scope mission-ready for 15 years, eliminating emergency battery failures in the field.

Integrated 3.25 MOA RMR Type 2 red dot crowns the fixed 4x scope for lightning-fast transitions from CQB to mid-range targets.

Forged 7075-T6 aluminum housing, combined with nitrogen purging, renders the optic shockproof, fogproof, and waterproof beyond 100 meters—exceeding MIL-SPEC endurance.

Bullet-drop compensator for .223 delivers holdovers to 600 meters, eliminating turret dialing under stress-induced scenarios.

Lightweight 14.96 oz chassis and 5.8 in length keep rifles balanced, promoting faster target transitions during dynamic drills.

Fully multi-coated lenses maximize light transmission, giving edge-to-edge clarity for identification at dawn or dusk.

Strengths: The ACOG TA01 scope’s fixed 4x scope delivers battle-tested durability and clarity, with its forged 7075-T6 aluminum housing enduring shocks while maintaining zero. The 36.8-ft field of view at 100 yds ensures rapid target acquisition. Battery-free tritium illumination lasts 12–15 years without maintenance.

Limitations: Its 1.5″ eye relief demands precise cheek weld and training. Tritium-only brightness can appear dim compared to LED options in both low light and daylight conditions. Fixed magnification limits ultra-close engagements under 25 yards, so pairing with a red dot is ideal.

How does the eye relief on the ACOG TA01 scope compare to other optics?
The fixed 4x scope has 1.5-inch eye relief, requiring nose-to-charging-handle positioning for proper sight picture.

Will tritium illumination fade over time, and what's the replacement cost?
Tritium has a 12-15 year lifespan; replacement costs $540-$600, depending on the model and warranty status.

Does the ACOG require tapping adjustments to track properly during zeroing?
Yes, lightly tap housing after turret adjustments to seat the internal prism mechanism for a consistent zero.

Can this ACOG work with night vision devices?
Tritium-only illumination is NVD-compatible but may appear dim; RMR offers adjustable brightness for optimal NVD use.

What warranty coverage applies if buying this optic used?
Lifetime warranty only covers the original owner; tritium illumination is not covered under the structural warranty for any owner.

How does battery life compare between ACOG and RMR components?
ACOG tritium lasts 12-15 years without batteries; RMR Type 2 provides 4+ years of continuous use on a CR2032 battery.

Why choose fixed 4x scope over variable power LPVO optics?
Fixed magnification offers superior durability, lighter weight, wider field of view, and simpler operation under stress.
