But, it will be cheaper and easier because the XM5 can be quickly rebarelled and magazines can get a new follower to hold something else.

Some are even predicting that the Army will do what they did with the M14, and decide to ditch 6.8x51mm for another round later. The 6.8x51mm ammunition is even more powerful than the M14’s 7.62×51/.308 Winchester ammunition, so the problem could end up being even worse. By 1970, the AR-15 became the M16 and replaced most M14 rifles in the field.Ĭritics of the XM5 say that we’re basically going back in time and making the same mistake the military did with the M14. Its weaker round and buffer system proved to be a lot more controllable, too.

The AR-15’s lighter weight and lighter ammunition allowed soldiers to not only pack lighter, but carry and fire more ammunition. Worse, soldiers found themselves struggling to maintain fire superiority over enemy forces, who were using variants of the AK-47, chambered in a lower-powered intermediate cartridge (7.62x39mm). It was also heavy and its wood stock didn’t hold up well in Vietnam’s humid environment. After less than a decade, it became clear that many soldiers just couldn’t handle the power when the weapon was placed in full-auto. The military didn’t stick with the M14 for long. The result was the M14 rifle, chambered in. That led to a long design process, where other improvements to both gun and ammunition were made. Experiments included replacing the eight-round en block clips with 20-round box magazines. Following World War II, it became apparent that the M1 Garand rifle needed improvement to better serve the armed forces. This move has generated a fair amount of criticism from gun and military writers, YouTubers, and others who are aware of the history of the U.S. The change will be limited to close combat forces, defined as basically anyone who gets in line-of-sight with the enemy, while support forces and others who are armed will stick with the M4 and 5.56x45mm NATO. In late April, the United States Army announced that they’ll be replacing the M4 and other M16-based rifles with the SIG Sauer MCX SPEAR, chambered for new ammunition, the 6.8x51mm Common Cartridge (AKA.
