Army revs up M4 carbine lethality upgrade

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 117,000 M4A1 upgrades on the way to the eventual transformation of more than 48,000 M4 rifles. The service recently marked a milestone of having completed one-fourth of its intended upgrades to benefit Soldiers in combat.

The Army is planning to convert all currently fielded M4 carbines to M4A1 carbines; approximately 483,000," Rowland said. "Most of the enhancements resulted from Soldier surveys conducted over time."

Rowland explained that the PIP involves a two-pronged effort; one part involves depot work to quickly transform existing M4s into M4A1s alongside a commensurate effort to acquire new M4A1 weapons from FN Herstal and Colt.

Army developers explain that conversions to the M4A1 represents the latest iteration in a long-standing service effort to improve the weapon.

"We continuously perform market research and maintain communications with the user for continuous improvements and to meet emerging requirements," Army statements said.

The Army has already made more than 90 performance "Engineering Change Proposals" to the M4 Carbine since its introduction, an Army document describes.

"Improvements have been made to the trigger assembly, extractor spring, recoil buffer, barrel chamber, magazine and bolt, as well as ergonomic changes to allow Soldiers to tailor the system to meet their needs," and Army statement said.

Today's M4 is quite different "under the hood" than its predecessors and tomorrow's M4A1 will be even further refined to provide Soldiers with an even more effective and reliable weapon system, Army statements said.

The M4A1 is also engineered to fire the emerging M885A1 Enhanced Performance Round, .556 ammunition designed with new, better penetrating and more lethal contours to exact more damage upon enemy targets.

"The M4A1 has improvements which take advantage of the M885A1. The round is better performing and is effective against light armor," an Army official told Scout Warrior.

Prior to the emergence of the M4A1 program, the Army had planned to acquire a new M4; numerous tests, industry demonstrations and requirements development exercises informed this effort, including a "shoot off" among potential suppliers.

Before its conversion into the M4A1, the M4 - while a battle tested weapon and known for many success – had become controversial due to combat Soldier complaints, such as reports of the weapon "jamming."

Future M4 Rifle Improvements?

While Army officials are not yet discussing any additional improvements to the M1A4 or planning to launch a new program of any kind, service officials do acknowledge ongoing conceptual discussion regarding ways to further integrate emerging technology into the weapon.

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," camouflage, removable iron sights and a single-stage trigger, according to numerous news reports and a formal government solicitation.The M4A1+ effort was designed to look for add-on components that will "seamlessly integrate with the current M4A1 Carbine ... without negatively impacting or affecting the performance or operation of the M4A1 weapon," a FedBizOpps document states.

Additional details of the M4A1+ effort were outlined in a report from Military.com's Matt Cox.

"One of the upgrades is an improved extended forward rail that will 'provide for a hand guard allowing for a free-floated barrel' for improved accuracy. The improved rail will also have to include a low-profile gas block that could spell the end of the M16/M4 design's traditional gas block and triangular fixed front sight," the report says.Despite the fact that the particular M4A1+ effort did not move forward, Army officials explain that market surveys regarding improvements to the weapon will continue; in addition, Army developers explain that the service is consistently immersed in

Despite the fact that the particular M4A1+ effort did not move forward, Army officials explain that market surveys regarding improvements to the weapon will continue; in addition, Army developers explain that the service is consistently immersed in effort to identify and integrate emerging technologies into the rifle as they become available. As a result, it is entirely conceivable that the Army will explore new requirements and technologies for the M4A1 as time goes on.

China and the US could end up in a war – here's what would happen

It's unlikely that the U.S.-China trade dispute is going to escalate to a full-scale war any time soon — but it's not impossible. Neither side is inclined to go to war with the other, but a war of that scale is what both plan to fight. All it would take is one bungled crisis, one itchy trigger finger, one malfunctioning automated defense system and the entire region could become a war zone.

This is how American pilots used drop tanks as bombs during WWII

If you pay attention, you might sometimes see long, cigar-shaped pods firmly attached to the undersides of classic fighter and attack aircraft, sometimes with unit markings on them.

Known as "drop tanks," these simple devices extend the range of the aircraft they're hooked up to by carrying extra usable fuel. Back during World War II, however, attack pilots found a secondary use for drop tanks as improvised bombs, used to bombard enemy ground positions.
