The U.S. Army's recent Request for Information (RFI) seeking a successor to the venerable M240 Medium Machine Gun has sent ripples through the competitive precision shooting community. Not for its ambitious caliber or weight reduction targets, but for its implicit demand for "increased lethality and accuracy." What, precisely, constitutes "accuracy" for a belt-fed, crew-served weapon capable of sustained suppressive fire at 800 rounds per minute? Our readers, accustomed to single-digit SDs and sub-0.25 MOA groups at 1000 yards, find the notion of applying precision rifle metrics to a machine gun… perplexing.
The RFI’s emphasis on "improved ballistic performance" suggests a future where suppressing an enemy position might involve truing DOPE for 1000-meter engagements, rather than simply hosing down a general area. Imagine the challenges of developing a load with a consistent velocity node across an entire belt of Link M192, let alone maintaining an SD under 10fps through a 24-inch medium contour barrel under sustained full auto. The barrel harmonics alone would be an engineer’s nightmare, likely necessitating a fully free-floated action within a monolithic chassis system just to manage the whip and maintain barrel consistency.
One can only speculate on the implications for future military qualification stage design. Will they involve engaging multiple PRS-style KD targets with an M240 variant from a tank trap, calling intricate wind for each 10-round burst? Or perhaps a positional shooting drill, where a bipod-mounted "Next Generation Medium Machine Gun" must be deployed on a modified tripod from a tank turret to engage 2 MOA steel at 600 yards within a 90-second par time. The logistical nightmare of maintaining cold bore consistency for a machine gun, let alone achieving a repeatable zero after 500 rounds downrange, seems almost insurmountable.
While we commend the Army's aspirational leap towards more precise combat systems, the competitive precision rifle community maintains a healthy skepticism regarding the practical application of true sub-MOA performance in a belt-fed platform designed for sustained fire. Perhaps they should simply issue every infantryman a custom barreled action chambered in 6 Dasher and call it a day.
