Duration: 13:02

This video compares the accuracy and zero retention of the FN SCAR 16S and Bushmaster ACR. While both rifles performed similarly with standard M193 55-grain ammunition (around 2 MOA), the SCAR 16S demonstrated superior accuracy with 69-grain match ammunition (1 MOA vs. 1.5 MOA for the ACR). The SCAR also exhibited significantly better zero retention after barrel removal compared to the ACR.

Quick Summary

The FN SCAR 16S outperformed the Bushmaster ACR in accuracy tests using 69-grain match ammunition, achieving 1 MOA versus the ACR's 1.5 MOA. The SCAR also demonstrated superior zero retention after barrel removal, showing minimal point of impact shift.

Frequently Asked Questions

How did the FN SCAR 16S and Bushmaster ACR compare in accuracy with M193 55-grain ammunition?

Both the FN SCAR 16S and Bushmaster ACR demonstrated similar accuracy when tested with M193 55-grain ball ammunition at 100 yards, producing groups of approximately 2 MOA.

Which rifle performed better with heavier match-grade ammunition?

The FN SCAR 16S, with its 1:7 twist barrel, achieved better accuracy (around 1 MOA) with Federal Gold Medal Match 69-grain ammunition compared to the Bushmaster ACR (around 1.5 MOA) with its 1:9 twist barrel.

How did the barrel swap affect the zero on the Bushmaster ACR and FN SCAR 16S?

The Bushmaster ACR experienced a point of impact shift of about 1.5 inches after its barrel was removed and remounted. The FN SCAR 16S showed virtually no shift, indicating superior zero retention.

What is the significance of barrel twist rate for rifle accuracy?

Barrel twist rate determines how well a barrel stabilizes bullets. Faster twists (lower number, e.g., 1:7) are generally better for heavier bullets, while slower twists (higher number, e.g., 1:9) are often better suited for lighter bullets.
