Published on April 17, 2025
Duration: 43:00

The FN SCAR 20 / Mk20 SSR demonstrates impressive practical accuracy, hitting targets out to 1,000 yards despite challenging windy conditions. While capable of sub-MOA, testing suggests a more realistic 1.5 MOA performance with extended strings. The rifle's longer barrel and increased dwell time contribute to a 'punchy' recoil, and its reliability is assessed as high in current 7.62 configurations, addressing past military concerns.

Quick Summary

The FN Mk20 SSR (SCAR 20) demonstrated practical accuracy to 1,000 yards, hitting targets with precise wind calls. Testing suggests a realistic performance of around 1.5 MOA, with a more 'punchy' recoil due to its 20-inch barrel. Current 7.62x51mm NATO models exhibit high reliability.

Frequently Asked Questions

What is the practical accuracy of the FN Mk20 SSR / SCAR 20 at long range?

During practical accuracy testing, the FN Mk20 SSR demonstrated the ability to hit targets at 1,000 yards. While capable of sub-MOA, the testing indicated a more realistic performance of around 1.5 MOA with extended strings of fire, especially under challenging conditions like high winds.

How does the recoil of the SCAR 20 compare to the SCAR 17?

The SCAR 20's recoil is described as more 'gassy' or 'punchy' compared to the SCAR 17. This is attributed to the longer 20-inch barrel and increased dwell time, which affects the gas system's operation without specific adjustments.

Is the FN SCAR 20 / Mk20 SSR reliable?

Based on the testing, current 7.62x51mm NATO SCAR systems, including the Mk20 SSR, show high reliability. This addresses some historical concerns regarding military versions, suggesting improvements in current production models.

What are the key differences between the SCAR 17 and SCAR 20?

The SCAR 20 features a longer 20-inch barrel (vs. 16-inch on SCAR 17), a 1:10 twist rate, an extended receiver for better accessory mounting, a Geissele two-stage trigger, and a fully adjustable precision stock.
