Frequently Asked Questions

Why did the U.S. Army choose the Sig Spear XM7 over the M4?

The U.S. Army selected the Sig Spear XM7, chambered in .308 Winchester, to replace the M4 primarily for its increased stopping power and ballistic performance. The .308 caliber offers superior energy transfer and penetration capabilities compared to the 5.56mm round used in the M4, making it more effective in various combat scenarios.

What are the key features of the Sig Spear rifle?

The Sig Spear rifle, particularly the .308 version, features a beefier handguard for a comfortable grip, a collapsible and stable buttstock, and dual charging handle options (rear and side lever). It is also available in both .308 and 5.56mm calibers, with the .308 variant being adopted by the U.S. Army as the XM7.

How does the .308 Sig Spear perform in ballistic tests compared to the 5.56mm version?

In ballistic tests, the .308 Sig Spear demonstrated significantly greater destructive potential. When fired at pumpkins and watermelons, the .308 rounds caused explosive disintegration, while the 5.56mm rounds had a much lesser effect. The .308 also showed superior penetration through multiple layers of copy paper.

What is the approximate price and accuracy expectation for the Sig Spear?

The Sig Spear rifle has an approximate MSRP of $4000. While it offers impressive features, accuracy tests at 100 yards with a 1-10 LPVO showed varied results depending on ammunition type, suggesting that optimal performance may require careful ammunition selection and potentially a higher-magnification scope for precision shooting.
