Why the M7 and 6.8x51mm are Bad Ideas

Professor Shane, a subject matter expert at Gun For Hire Range, discusses the U.S. military's transition from the M4 to the SIG XM7 (M7) rifle. He expresses skepticism regarding the platform change, highlighting concerns about increased recoil, reduced ammo capacity due to heavier 6.8x51mm rounds, and significantly decreased barrel longevity compared to 5.56x45mm NATO platforms. While acknowledging the 6.8mm cartridge's effectiveness in the M250 machine gun, he questions its suitability for the M7 rifle, suggesting that higher hit probability is achieved through greater ammunition availability rather than a higher-pressure round with a shorter barrel life.

This analysis by Ian McCollum of Forgotten Weapons critically examines the US Army's adoption of the SIG Sauer M7 rifle and the 6.8x51mm caliber. McCollum, a recognized firearms expert, argues that the justifications for the NGSW program—extending engagement range and defeating advanced body armor—are flawed. He suggests that modern drone technology is a more effective solution for long-range threats and that advanced bullet design, rather than extreme pressure, is a better approach to armor penetration. The analysis highlights practical engagement limitations due to visibility and terrain, advocating for the role of the Designated Marksman over a universal heavy rifle. McCollum predicts the M7's adoption may be short-lived due to its inherent drawbacks.
