The Army is expected to begin fielding the XM8, a shorter, lighter carbine version of the M7 Next Generation Squad Weapon rifle, towards the end of the year.

The Army has another new rifle, the XM8 carbine

The XM8 carbine has a shorter barrel and suppressor than the M7, and is also about a pound lighter than the rifle.

The XM8 is just over 32 inches long overall, compared to 37 inches for the M7, with a barrel length dropped from 13 to 11 inches and its suppressor from 7 to 6 inches, Shoemaker said.

The carbine is also lighter than the M7, Shoemaker said. Without the suppressor, the XM8 weighs 7.33 pounds while the M7 weighs 8.36 pounds. The carbine’s suppressor shaves down to 1.31 pounds from the M7’s 1.46 pounds.

In case anyone wasn't sure

The XM8 shares internal firing components with the Army’s new M7 rifle, firing a 6.8 x 51mm round.

I don't know much about this round. I'll have to research. If this is what our military is using, do you thing we can expect it to become common for civilian use?
Or, are there too many 223/5.56 already ?

About a year after I got out, I made the mistake of joining the National Guard.

Now bear in mind that I was an Air Winger in the Corps, that's about as far away from the Infantry as a Marine can get.

I was told I needed to dial it back, a LOT....

I was initially classed an MP, and then got re-classed as an Artillery Radar Operator.

Going from the MPs to the Artillery was going from Bad to WORSE......

My MP unit was filled with soldiers who'd not qualified with a rifle since basic training. Going to the Artillery was even worse as far as individual marksmanship went.

From the lowest Private, to our battery First Sargeant, weren't qualified on the M4, or the M9.

Between rushed "check the box" training, and a clique system the likes of which I never saw as a Marine, I was damn near driven to the end of my rope.

A rifleman first. A Marine after.

A story I have told here before.
Dad was active duty Marine ‘58-62. Shot expert in basic and was an avid hunter growing up with his dad. He was a natural with a rifle.
Fast forward to years ago when my dad was 70+ yrs old and had not touched a military rifle since ‘62. Deer rifles, every year.
He wanted to shoot my Colt M4.
Showed him the workings of it and handed him a mag.
He put all rounds touching on bull.
Basically he handed it back and did a “dad” version of drop mic smiling ear to ear. Looked at me and said: “always a Marine” or such to effect 😁🇺🇸🇺🇸

5.56/.223 will be here after I'm long gone, it will live on like the 30.06 Winchester, my grandkids will be shooting 5.56, if the govment hasn't taken all the guns away by then.
 
The civilian version of the 6.8x51 is called the .277 Fury.

Thread 'Cartridge of the Week: The .277 Sig Fury'

1667145149469.png

The .277 Fury or 6.8×51mm Common Cartridge, (designated as the .277 SIG Fury by the SAAMI) is a centerfire rimless bottlenecked rifle cartridge announced by SIG Sauer in late 2019.

The SAAMI warns that MAP levels greater than 65,000 psi (448.2 MPa) may present an increased risk of unsafe cartridge case or firearm rupture and thus require cartridge case and firearm designs that depart from traditional practices (materials, construction, and other design criteria). Its hybrid three-piece cartridge case has a steel case head and brass body connected by an aluminum locking washer...

First order of business is to admit that I am old, not so much in years as experience and study. That said;

What on earth do we need with a new cartridge??? The 7-08, and 260 REM have been around for years now, and others have come and gone. Both of them are available in the AR10 platforms as is anything else based on the 308 case. It makes no sense to spend time and money for something that is already been done. Kinda like reinventing the wheel...

Just my rambling opinion

How else can the military complex rip off the taxpayer for a few billion without changing armament, it's always about money!

With the ops in Afghanistan (mostly) and Iraq, the troop were being "out-ranged" by enemy fire.

Basically, the US Army wasn't comfortable with the idea during the Afghanistan War that US squads with 5.56 mm M4/M16 and M249 were being out-ranged by enemy personnel utilizing 7.62x54mmR weaponry. Essentially, the 7.62x54mmR weapons like SVD rifles and PK machine guns allowed the OPFOR to engage from 800+ meters away while the 5.56 mm weapons were only able to engage ~500 m effectively.

Also, there was a need to increase the stopping power because in Afghanistan they found out the 5.56 wasn't putting & keeping down the insurgents reliably when they were hit. That's when they started introducing the 77 gr. Mk.262 loads that were more effective.

The advantage of 6.8x51 is that it has higher muzzle velocity, higher muzzle energy and a much flatter trajectory than the 5.56 and 7.62x51 (and the 7mm/08 & 260 Rem) and does all this out of a 13” barrel.

The front-line combat formations and combat service support units will be fielding the new M7/8 rifles & M250 MGPMGs. Majority of the rear echelon units and probably all of the reserves and guard units are still keeping their M4’s for the foreseeable future.

So, riddle me this...

#1 - Were there any complaints when the M16/5.56 was first adopted? :unsure: I think it took awhile to get the bugs out in the A2, and they moved to a 62/64 gr bullet for more effectiveness against supposed Russian armor, when they figured out the 55 gr pill wouldn't cut the mustard.

#2 - Why didn't the US Armed Forces use the "heavy" M1 Garand/30-06 when the lighter M1 carbine/.30 carbine was available and the troops then could have a lighter & higher ammo load-out? :unsure:

#3 - Why did the USMC move to the lower-performance M4 carbine due to the US Army experience in Afghanistan when they had higher-performance A2/A4s, other than the M4s were easier to carry when in vehicles? :unsure:

With all being equal, pressure, bullet weight, etc, there's nothing to be gained from the new wonder cartridge. You can not get over physics. Change of weapon when there's already a viable system in place, makes no sense to me. Change the upper on the AR 10 to the 260 REM, loaded to the same pressures with the same bullet weight and it will perform the same. Physics.

Not quite. The 260 was tested and didn't pass muster.
