Proposed M-16, M-4 replacement under review

XM8 weapon family to be assessed

The Soldier Battlelab, formerly known as Dismounted Battle Space Battlelab, will assess the weapons family proposed to replace the M-16 and M-4 weapons systems this month to see if the weapons will move forward in development.

Soldiers, Marines and airmen will evaluate the XM8 weapons system performance. The Soldier Battlelab will look at the weapons' performance and subjective user data.

The weapons are currently in preproduction, and the assessment will look for areas that may not function properly and still need to be addressed, said Jerry Barricks, project officer with Soldier Battlelab.

"(The evaluation will) not only gather technical data, but also subjective data on the ease of use and if it's easy to maintain or train on," he said.

The XM8 family has a 9-inch compact, 12.5-inch carbine and a 20-inch sharpshooter and automatic rifle.
The 12.5-inch carbine is 6.4 pounds with an objective of 5.7 pounds and is 33 inches with its adjustable stock extended. The M-16 A2 is 39.63 inches long and 8.79 pounds with a 30-round magazine.
Internally, the XM8 uses a rotary locking bolt system that functions and fieldstrips like those used in the M-16 rifle and M-4 carbine, according to the XM8 manufacturer's - Heckler & Koch - Web site. The bolt is powered by a unique gas operating system with a user-removable gas piston and pusher rod to operate the mechanism. Unlike the current M-4 and M-16 direct gas system with gas tube, the XM8 gas system does not introduce propellant gases and carbon back into the weapon's receiver during firing.

"(The Soldier's input) is a good way to look at (a variety) of things and go back to refine our requirement document instead of sitting here thinking about it," said Edwin Davis, deputy director of the Soldier Battlelab.

"A lot of weapons are impressive on the range," Davis said, but the weapons' true performance isn't known until it's put in the hands of Soldiers, who "move it around, get a feel for it, get it in the mud."

The weapons will be evaluated with known distance, field fire, NBC, night fire and rapid magazine change with some Soldiers also doing MOUT, close quarter battle and a woodland obstacle course.
During the review, the XM8s will be compared to the M-16 A2, M-16 A4 and M-4 weapons systems.

Although there's no great outcry from Soldiers in the field to replace their current weapon, there's a push to get gear into the field faster. The data will be used to help refine the requirements document for the new weapons systems or even decide if there's a need.

The Infantry School's assessment on the weapons systems should be out by mid-May, Davis said.
"A weapon is a fundamental skill for every Soldier," Davis said. "The quicker we can train them up on the task, the better we will be."

Here is the information from Heckler&Koch's website. The article addresses the zeroing of the sight, and there are also a couple of videos at the bottom.

while in hhc there were 4 guys that i knew who were on a detail for battlelab everyday, where there are testing the xm8 right now. from what i gather, the thing barely ever jams, i think this has the potential to be a great weapon.

"Word on the street" is that the xm-8 will be shelved........the next m4 replacments probably being the HK M4 upper (no gas tube) or something in the new 6.8mm.

I just got back from the spring Knob Creek machine gun shoot. For those that may have never heard of it, Knob Creek Gun Range, just outside of Ft. Knox, puts on a huge gun show and machine gun shoot twice per year. Class III dealers come from all over the country for the event. A man can rent trigger time on everything from a little MP-5 to a quad - .50, to a minigun.

They had the H&K reps up there doing a presentation on the XM-8. To be honest, I would hate to see this thing replace the M-4. The XM-8 is designed to be totally modular, and totally ambidextuous. The mag release is on the front of the trigger guard (like on the AK). I can tell you from experience that this sucks when you are used to the functioning of an AR platform.

The charging handle is on top of the weapon, and can be rotated to either side and pulled to the rear from either side, to accomodate southpaw shooters.

The bolt release is located inside the trigger guard, also lending itself to southpaw shooters.

The rep demonstrated the "unsurpassed controlability" of this weapon on full auto. However, one must remember that this is a trained professional shooter that knows how to control a weapon of full auto. My money would bet that he could do the same thing with an M-4. Not to mention the "tactical No Go" of a combat rifleman firing on full auto.

The rep then buried the weapon under gravel, picked it up, emtied a mag, and claimed it is the most reliable weapon in the world, almost never malfunctioning. It would take more than that to prove it to me, considering that the AR platform was been battle proven time and again, and the XM-8 hasn't.

One thing that did kind of impress me, though. The rep changed the configuration to that of an auto rifleman, with the bipod on the front. He fired to weapon on full auto, and instead of having a "beaten zone" like on the old 60's, etc., he was pretty much able to deliver aimed fully auto fire, and put the rounds exactly where he wanted them - firing from the prone of course.

The grenade laucher is very, very short. I'm not sure, but it looked like the external ballistics might be affected. Or, maybe it has just been a while, but on the test rounds he fired (at around 200m), the ballistic arch looked overly pronounced, begging the question of whether the effective ranges of this one are different than the M203.

I just didn't have a "warm, fuzzy" about it. It honestly didn't look and feel like a weapon that would hold up to the abuses that a Ranger Company would put it through.

After the demo, I spoke with on of the reps, and he actually stated that he hoped the government didn't pick it up, because then they would want to make changes to the weapon. He hoped it would be able to remain in the private market - which didn't really make a lot of sense to me. I know my safe is not loaded with fully auto rifles with grenade launchers mounted on them.

It feels more flimsy than it looks.

CD, is the launcher a over under config? I don't see anything that would look like a launcher in the above pic.

You didn't happen to test fire anything in the 6.5 Grendel did you ? I will agree that the 6.8 SPC has to be better than the 5.56mm, but the 6.5 Grendel has better ballistics,on paper anyways, than the 6.8 SPC.

I'm assuming they made improvements in the M4 compaired to the M16 A2s, as far as the elements causing jamming?

Luna:

It is an over/under config like is currently used on the M-4. But due to the ergonomics of the XM-8 it seems to be mounted more forward of the rifle - hence the shorter barrell for the grenade launcher.

In addition, the rifle only has a 12.5" barrell. Now, I'm not a weapon manufacturer, but even I know that you won't get top notch performance out of a 5.56mm out of a 12.5" barrell. Yeah, there are AR configs out there with even shorter barrells, but they are not designed to be a main battle rifle. And the reps did not answer my question to my satisfaction about how they overcame the barrell length without sacrificing ballistic perfomance. It may have a role as a MOUT type weapon, but not as a battle rifle, IMHO.

Thorn:

Nope, I didn't shoot anything. I have a hangup about paying somebody $50 to fire 50 rnds through a weapon - unless it is truly an exotic weapon. And I did not see either the 6.8 or the 6.5 up there. Most of what I saw were SAWs, 60's, M2s, miniguns, MP-5s, M-4s, M16A1s, and things like that. The XM-8 is the only thing I saw up there that I would consider as being exotic - and they were not renting it out.

So, I just watched people stand in line to drop $100+ a pop to shoot one of the miniguns, and their ammo lasted about 3 seconds.

So where do you keep your grenade launchers ?
