In the end, the SEALs mostly stuck to Colt's 30-round magazines in their M16 rifles and later carbine variants, including the now ubiquitous M-4.
One of the significant tradeoffs in replacing the M60 with the M249 was power and range. The M60, warts and all, fired the heavier 7.62-millimeter round. The smaller caliber M249 generated 1,093 square-foot pounds of muzzle energy and had a maximum effective range of 1,094 yards.
Machine guns are legal at the federal level but highly regulated. This goes back to the National Firearms Act of 1934 (NFA), which was enacted as part of the Internal Revenue Code, and was the first federal regulation of the manufacture and transfer of firearms. Items on the NFA list can still be owned.
Why didn't the US Army adopt the Stoner 63 as a general issue weapon? Because when it was tested in military service (literally issued for combat service in Vietnam to line infantry) by the Marines, it was found to have few, if any significant advantages over the M16, plenty of disadvantages, and it cost more.
These days, the U.S. does not field AK-47s, but some members of its military are trained to use them. Special operations forces from all branches might have to pick up an enemy AK-47 at some point because of the nature of their work -- sometimes help isn't coming.

historically, the original M60 was plagued with issues. it had issues ripping the rim off of cases in mid-ejection, and the feed tray was flimsy and prone to breaking.
Features: The Squad Automatic Weapon (SAW), or 5.56mm M249 is an individually portable, gas operated, magazine or disintegrating metallic link-belt fed, light machine gun with fixed headspace and quick change barrel feature.
M60 General-Purpose Machine Gun
They are similar in appearance, portability, weight, and mission. The M60 is slower at 500-650 rpm, while the M240's cyclic rate is selectable from 750-950 rpm. The M60 is effective to 1,200 yds, while the M240 is effective up to 1,800+ yards.
Comfortable Shooter. Using its bipod, the M60 had a maximum effective range of 800 meters (the measurement used in U.S. manuals). Typically, every soldier in a rifle squad carried a supply of 200 linked rounds of ammunition for the M60, a spare barrel, or both.

The weapon chosen to replace the M249 was the modified HK416, later designated the M27 IAR. The M249 SAW is still in use as a squad automatic weapon by the US Army. In 2019 US Army launched Next Generation Squad Weapon - Automatic Rifle program to find replacement for M249 SAW and replacement for 5.56×45mm NATO round.
Machine guns are available in caliber 5.45, 5.56, 7.62, 12.7 and 14.5 mm. Single shot grenade launchers have a caliber of 40 mm, and generally fire a HE (high explosive) grenade out to a maximum range of about 400 meters.
For a machine gunner operating either the 7.62 GPMG or FN Minimi saw machine gun, it would be around 800 rounds for a standard patrol (take into account that each ammo belt holds around 100-200 rounds) and that unless in a fire support mode, fire in 5 round bursts (20 round bursts for fire support/suppressive fire).
The M240B is a general-purpose machine gun. It can be mounted on a bipod, tripod, aircraft, or vehicle. The M240B is a belt-fed, air-cooled, gas-operated, fully automatic machine gun that fires from the open bolt position. As the gun is fired, the belt links separate and are ejected from the side.
The biggest issue among M249 SAW gunners is the 200 round plastic ammunition box. Some box and weapon interfaces were observed as weak and unreliable. The box was extremely brittle and prone to break, especially at the box and weapon interface.

The M240B machine gun is one of the most important weapons assigned to platoons and companies. The large caliber 7.62 ammunition and high rate of fire make it invaluable in supporting attacks and ambushes as well as protecting defensive areas and mounted patrols.
