6.8 mm ammunition reflects the development thinking of small arms in the United States

Development of more powerful，lighter and more accurate rifle ammunition between medium and small calibre

The US Army will lead the trend of new caliber ammunition and firearms again ?

Hello, everyone. I'm Quan Yanbing.

Today we're going to talk about the U. S. Army's 6.8 mm ammunition and firearms.

According to these media reports,

the Army plans to finalize the design of the next-generation crew weapon in the first quarter of 2022

In 2023, then begins to gradually change its equipment

and took the lead in equipping 8.6 mm rifles and heavy machine guns in the world

Since the 1960s,

the small-caliber rifle has always been a three-pronged situation,

NATO's 5.56 mm,

Russia's 5.45 mm,

and our country's 5.8 mm.

But the lack of power of small-caliber bullets has also been hitting the situation.

The Americans quietly launched the xm8 rifle as a replacement

for the M16 rifle and the m4 carbine,

but the project was cancelled in 2005

Friends who like to play shooting games should be familiar with the xm8 rifle,

which we can see in many online games more than 10 years ago.

At the request of the United States special forces,

Barrett introduced the 6. 8mm caliber ar-15 rifle and named it the M468 special purpose carbine.

4 means produced in 2004， 68 means the caliber is 6.8mm,

the m468 is just an upper receiver including the barrel,

M16 rifle and the M4 carbine can fire 6.8mm special purpose ammunition after replacing this.

The Next Generation Crew Weapon is a firearm development program officially launched by the U.S. Army in July 2018,

which is mainly used to replace the existing 5.56mm M4,M-4A1 carbine and M249 light machine gun.

The Army's goal is to gain a generational advantage with new ammunition that can penetrate body armor with a more powerful 6.8mm

The 6.8mm cartridge is clearly in the 7.62x51mm rifle and 5.56 × 45 mm small caliber rifle cartridge,

which is a result of seeking balance.

The speed of research and development of firearms is not too fast now.

The development of firearms has entered a bottleneck period in many aspects.

Before there is a breakthrough in the field of ammunition

it is very difficult for the old ammunition system to improve its power

and it is not very likely to improve the density of firepower

Because the bottleneck of firepower density and projection

depends on the ability of unilateral carrying and logistics support,

not just the gun itself.

The American's previous xm-8 rifle was just a matter of ease of use or lightweight

The empty weight of the xm-8 rifle is only 2.8 kilograms,

and the empty weight of the M-16 series rifles is more than 3.1 kilograms.

However, the xm8 has sacrificed the important index of gun design accuracy,

which is also the most direct reason for the final failure of the XM-8

The 6.8mm ammunition also reflects the development thinking of American small arms.

Development of more powerful, ighter and more accurate rifle ammunition between medium and ighter and more accurate rifle ammunition between medium and

Will the US Army lead the trend of new caliber ammunition and firearms again ?

Judging from the current situation,

Australia and Britain have made it clear that they will follow the US military in testing and equipping the 6.8mm gun line,

but will other US allies abandon the 5.56mm and switch to 6.8mm ammunition?

China and Russia upgrade 5.8mm and 5.45mm ammunition

to 6.8mm Millimeter or so of ammunition and firearms

I personally think that these possibilities will not be too big

Any change in the calibre of a weapon system cannot be accomplished soon

Because it is not only related to the performance of the bullet and the whole weapon system,

but also to the production of the national military system.

Russia has also experimented with the 6 mm cartridge

and has developed a light machine gun of the same caliber

The 6.8 mm cartridge looks okay,

It's not as powerful as that of 7.62 mm.

In terms of cost and versatility

it's not as good as the original 5.56mm cartridge

and that's all for today

See you next time.
