You don’t want to face them in battle.
Within the last few years, the Army did conduct a “market survey” with which to explore a host of additional upgrades to the M4A1; These previous considerations, called the M4A1+ effort, analyzed by Army developers and then shelved. Among the options explored by the Army and industry included the use of a “flash suppressor,” camoflauge, removable iron sights and a single-stage trigger, according to numerous news reports and a formal government solicitation.
The US Army has now produced at least 117,000 battle-tested, upgraded M4A1 rifles engineered to more quickly identify, attack and destroy enemy targets with full auto-capability, consistent trigger-pull and a slightly heavier barrel, service officials said.
The service’s so-called M4 Product Improvement Program, or PIP, is a far-reaching initiative to upgrade the Army’s entire current inventory of M4 rifles into higher-tech, durable and more lethal M4A1 weapons, Army spokesman Pete Rowland, spokesman for PM Soldier Weapons, told Scout Warrior in an interview.

“The heavier barrel is more durable and has greater capacity to maintain accuracy and zero while withstanding the heat produced by high volumes of fire. New and upgraded M4A1s will also receive ambidextrous fire control,” an Army statement said.
To date, the Army has completed more than 117,000 M4A1 upgrades on the way to the eventual transformation of more than 480,000 M4 rifles. The service recently marked a milestone of having completed one-fourth of its intended upgrades to benefit Soldiers in combat.
