Taiwanese Type 91 to 500yds: Practical Accuracy

Published on January 5, 2023
Duration: 26:04

This video details a practical accuracy test of the Taiwanese Type 91 (T91) service rifle, chambered in 5.56x45mm NATO, out to 500 yards. Conducted by experts Henry Chan and Josh Mazzola at The Ranch in Eagle Lake, Texas, the drill highlights the rifle's performance under gusty conditions. The T91, equipped with a Trijicon ACOG TA31, demonstrated consistent impacts from 150 to 400 yards, with challenges at longer distances primarily attributed to wind. The session also touches upon the T91's historical context and design evolution, comparing its short-stroke gas piston system to other platforms.

Quick Summary

The Taiwanese Type 91 (T91) rifle, chambered in 5.56x45mm NATO, was tested for practical accuracy out to 500 yards. Equipped with a Trijicon ACOG TA31, the rifle performed reliably from 150-400 yards, with longer distances requiring careful windage and elevation adjustments. Its short-stroke gas piston system contributes to a distinct recoil impulse.

Frequently Asked Questions

What are the key technical specifications of the Taiwanese Type 91 (T91) rifle?

The T91 rifle is chambered in 5.56x45mm NATO, has a length of 819mm (32.25 inches), and weighs 3.69 kg (8.13 lbs). It utilizes a short-stroke gas piston operating system and was tested with a Trijicon ACOG TA31 4x32 optic.

How does the T91 perform in practical accuracy tests out to 500 yards?

In practical accuracy tests, the T91 demonstrated reliable impacts from 150 to 400 yards. At 450 and 500 yards, accuracy was achieved but required precise windage and elevation adjustments due to environmental factors like wind.

What is the operating system of the T91 rifle and how does it compare to others?

The T91 uses a short-stroke gas piston system, distinct from the direct impingement system of the M4/M16. This system is also found in rifles like the HK416 and G36, though the T91 features a unique long-linkage design.

What ammunition was used in the T91 accuracy test and what were the environmental conditions?

The test utilized GGG .223 (Lithuanian) ammunition, noted to have 5.56 NATO velocity. Environmental conditions included gusty winds of 3-9 mph and 89% relative humidity at The Ranch in Eagle Lake, Texas.
