I would focus more on the free-float aspect of these rifles than full auto, although auto can have a limited usefulness for a trained shooter.

Mag dumps like Russian sub machine gun battalions is not what we are talking about here.

Come on now. You know the military's mentality. A rifle is "never" clean. Troops will not be able to save any time on this system with cleaning. They'll still be cleaning the fuck out of those things and getting the white glove bullshit.

If you shoot any piston gun, like an AK47/74. You'll notice that you still gun a TON of carbon inside the receiver and action. I got like a milimeter or 2 of carbon inside my AK74. If I put my finger inside that thing, it comes out black.

Or the 249 and 240, both got real dirty inside the receiver and on the bolt carrier assembly. Piston guns are NOT cleaner than "DI" rifles like the M16 family.

Only thing I can say about that is that the operating system on an AK or 240/249 is a long stroke piston, so you have all the gas from the barrel being about to flow through the gas tubes and into the receivers as the BCGs cycle. Short stroke piston guns don't have that going on, since you're using the gas to smack a piston into another piston.

It takes longer to clean the upper receiver, BCG, and now gas block, plug and piston assembly.

It all makes sense now.  Gotta keep that blotter report down with extra hours in weapons maintenance.

Cleaning external piston designs and their gas blocks is a lot of fun.

Who was always the last soldier to be done cleaning his weapon?

SAW and 240 gunners.

Ever had to clean a FAL in the field?

Real easy, right?  Nope

Biggest problem with the SAW is that it is an AK at heart-beats itself to pieces with early receiver wear, critical dimensions stretched this way and that, gas tubes eroded, garbage.

As a former USMC 0311/SAWgunner I think there are situations where a belt fed is extremely valuable in combat. I was glad to be one and kind of concerned about the lack of them in the current line units being used.

Maybe with the influx of the IAR we will see the return or the 249 for the fire team

This RFI is geared towards replacing SAWs in the Rifle Squads, which is why the number is 11,000 and not tens of thousands.

Some of you in this thread don't seem to be capable of addition and subtraction, let alone basic analysis of the numbers.

There are way more Marines in the various commands in Infantry Battalions than 11,000.

There are 32 Marine Infantry Battalions folks by my count.  A Marine Infantry Squad has 3 Fire Teams.

This number only makes sense for SAWs or DMs, and they don't seem to have doctrine yet for DMs, so that leaves SAWs, which is what they have been talking about using the IAR for.

For everyone that thinks the HK416 is a panacea of problem-solving, it has created more problems than most know, some of which have been addressed by the HK416A2, HK416A3, and HK416A5.

One of the latest band-aids for problems you see with an external piston gun and the instantaneous violent carrier inertia is a disconnector protective basket for extreme hammer slap against the disconnector tail.

By going with a 1920s-era (at best) external piston design, you create a design problem the internal expansion system addressed, in addition to regressing back to off-axis reciprocating mass.

HK tries to tame this with a heavier carrier, heavier buffer, and higher action spring rate-all of which have 2nd and 3rd order effects on the gun and ancillary systems.

But hey, why stop when you're on a winning streak of SVT-style piston insanity?

I would not purposely deploy with this rifle for dismounted infantry patrolling.

For short-duration DA missions with a little bird and crash hawks waiting to pick you up, you won't be seeing the same level of exposure to dust and sand, and with a budget that allows one to toss uppers and slap on new ones, or even frequent replacement of entire guns, the relevancy for the Marines is not there at all.

When these little band-aids start rearing their heads as the years rack up, armorers are going to be wondering what was going on here.

M27 ain't either, not with M855A1 nor Mk318. They'll go beyond 4 MOA before 20K rounds when you're doing a lot of automatic fire.

Am I the only one who remembers that the XM8 trials and the ICC were rigged against the M4?

They had brand new rifles with newly designed magazines, competing against previously-issued M4 carbines with older magazines. Not to mention, their standards of maintenance were "as little lube as possible" which is not SOP for the M4 carbine.

Finally, a lot of the stoppages were operator-induced, since dipshits did not understand the M4's burst FCG and counted trigger resets as stoppages. IE, fire the last round in the gun on burst, then when you reload and pull the trigger, the gun will not fire three rounds because the burst mechanism has not fully reset.

Whichever shitbird jackass came up with the burst trigger can eat a dick. Worst thing they ever did to the M16.

http://coresurvival.com/wp-content/uploads/2012/07/75th-RGR-D-Co.-2nd-BTN-side-profile-of-HS-5.jpg

Replace the trigger and I believe the DD rail weights a bit less. Remove fixed front sight because they're issued ACOGs, throw on a cheap back up sight. Think it still allows for an M203 or M320 to be attached to. Maybe change the barrel to, but I believe the USMC still uses the M203 so they will probably want to keep the notch in the barrel? Anyways, seems like most of the advantages of the M27 over the standard issue M4 can be applied as an upgrade fairly easily.

It hasn't been every time, but the XM8 and ICC trials, whose results you drew upon earlier, were stacked against the M4. When dumbasses call the trigger reset a malfunction, that is improper testing, because the weapon did not malfunction.

Comparing older rifles that have been kicking around for five to ten years against brand-new rifles is disingenuous at best. 90% of problems with M4's and M16's are magazine-related, since the Army and USMC treat mags like they're worth their weight in gold. The Corps is now issuing Gen 3 Pmags exclusively, so I'm willing to bet there will be far fewer malfunctions reported.

Wade is pushing the M27 because it's easier to get that made standard-issue than it would be to properly upgrade the M4 to have the same features. And that's even considering the fact that the M27 is more expensive, both in per-rifle and maintenance costs. That's because military procurement is retarded.

Switching to the M27 is a bad move, because then you will run into issues with it ten or twenty years from now; the kind of issues that we are already aware of in regards to the M4.

On to the HK417 abortion.  It didn't win their competition because of the gun.  The Army's record for rifle competitions is abysmal, if you study any of the history.  We would never have gotten the AR15 if it weren't for direct Presidential and SECDEF involvement, and then they still did everything in their power to sabotage the AR15 before, during, and after adoption, to include sending rifles to Vietnam with cartridges loaded with ball propellant that they knew caused the guns to malfunction, after proofing them with the original extruded propellant cartridges it was designed around.

They also mis-handled the M110 so poorly by requiring HPT on the bolts, against the recommendations of everyone with a brain, that you actually see M110 bolts shearing lugs, whereas you just didn't see this with the SR25, and why the units that have the COTS authority still buy SR25s from KAC without M110 TDP specs.

So your arguments are based on a fundamental misunderstanding or ignorance of USMC force structure, and the premise that the Army makes good decisions with its rifle competitions, as long as HK is the beneficiary.

I have a feeling once the M110A1 comes online the units procuring COSTS KAC SR-25 will likely stop, just like how if the 416 replaces the M4 I doubt SOCOM would say "nah were keeping our M4A1s and SR-25ECC s".

Why is it every time the M4 finishes last in trials it's rigged?

Have the Marine Corps been rigging the M16 and M4 for the past 10 years in Afghanistan?

Because according to Gunner Wade when he was on here he came out and said the M27 has far better reliability and durability.

It's because people are lying unless what they have written agrees with what the person has programmed himself to believe.

Bro, you take a lot of heat here.      You put the target on voluntarily, but that's beside the point.

Many have accurately predicted this, and those persons still have a full hand of nostradamus cards to play, and the crystal ball isn't looking good for DI.   For what it's worth, I remember from threads months/years ago, you defended the DI system vigorously.   We boxed on that a few times.

There had to be some process of discovery that led you to this conclusion.  I'm wondering what it was and how it came about.  

FWIW, I give you respect for being able to set down a tremendous amount of proclivity and prejudice, for doing your own research and study and standing by the conclusion you reached.    

Just curious about what you saw out the window on the journey to the actual today.

For everyone that thinks the HK416 is a panacea of problem-solving, it has created more problems than most know, some of which have been addressed by the HK416A2, HK416A3, and HK416A5.

One of the latest band-aids for problems you see with an external piston gun and the instantaneous violent carrier inertia is a disconnector protective basket for extreme hammer slap against the disconnector tail.

By going with a 1920s-era (at best) external piston design, you create a design problem the internal expansion system addressed, in addition to regressing back to off-axis reciprocating mass.

HK tries to tame this with a heavier carrier, heavier buffer, and higher action spring rate-all of which have 2nd and 3rd order effects on the gun and ancillary systems.

But hey, why stop when you're on a winning streak of SVT-style piston insanity?

I would not purposely deploy with this rifle for dismounted infantry patrolling.

For short-duration DA missions with a little bird and crash hawks waiting to pick you up, you won't be seeing the same level of exposure to dust and sand, and with a budget that allows one to toss uppers and slap on new ones, or even frequent replacement of entire guns, the relevancy for the Marines is not there at all.

When these little band-aids start rearing their heads as the years rack up, armorers are going to be wondering what was going on here.


Norway has been having no problems with their rifles since the initial AGP was fixed.

Arctic 1 posted a lot of his 416 over his 4 years in the Norwegian military on other sites.

Nordic Battle Group in Afghanistan had catastrophic failures with brand new HK416s.

The design does not do well with high sand/dust environments in the real world because you just placed one of the critical components outside of the protective enclosure of the upper receiver.

Congrats on making the M4 into 8x the cost with an SVT-38 abortion of an operating system.  Bier all around, Americans got the bill, ha ha!

Danes told me they preferred pulling the FCG out of the 416 and dropping into a better carbine, the C8, no problems.

Colt Canada engineers refer to the 416 as a total abortion, with features that require more features to fix the problems those features created.

The biggest design flaw of an external piston system that can't be ignored is that you violently and instantaneously power up the op rod with gas, which immediately begins to move the carrier.

In the Stoner internal expansion system, the gas has to flow into the carrier/bolt/piston chamber, and fill the volume of that chamber to generate inertia, which buys you some precious fractions of a second of time while the case rebounds from obturation.

Now you see why the 416 has the carrier, buffer, and spring weights that it does, which now increase return-to-battery stroke impact on the barrel extension, which then requires a heavier buffer to counter carrier bounce on automatic, which requires more gas.

More gas you say?  Lets open the port, but then add an adjustable regulator.

More gas powers up the face of the piston with more volume per time, increasing carrier inertia again, requiring more weights, higher spring rate.

More spring rate increases carrier velocity on the return stroke, increasing carrier bounce.

Guys are complaining about barrel weight, so they want a lighter barrel.

Oh, and they're going to suppress too.

Exactly, and Cwo5 Wade says the M27 far surpasses the M4 across the board and can be had.

None of this "if only we get a new rail, trigger, BCG, and CH in the M4" because we're not getting those things.

The M4 is stuck in TDP limbo, with no upgrades in sight.

The Army recently shit canned any attempt to improve the M4 because "nothing on the market was an improvement over what we got".

So let's not discuss what could be, let's discuss what is here, right now, available and easy to get.

USMC Infantry Battalions are large, because Rifle Squads are large, and you have several different companies in addition to what you would see in the Army.

With 24 active duty Infantry battalions, that's way more than 11,000 rifles could ever hope to fill.  Look up MCRP 5-12D, amended Feb 15, 2016.  The USMC has much larger infantry battalions than the US Army because it actually has Infantry Squads, not oversized fire teams like in the Army meant to squish into Bradleys, even though most of the Infantry MTOE units don't ride in Bradleys.

We're not even talking about all the Light Armored Reconnaissance Battalions either, or Artillery batteries, Air Wing, MARSOC, etc., just Infantry battalions.

Now look at how many SAWs there are USMC-wide. Most Marines have no clue about the greater organizational MTO&E because they don't need to know, and don't care to either.  Most do a term and can't wait to get out once their enlistment is up, which is fine.

Are you saying that op rods are bad, or thatthe 416 poorly executes something that is not inherently bad?

I am not a SME on the 416.  I would say that in general, the gas operated semiauto weapons with a reputation for being the most reliable, are those with op rods, not DU.

Trying to clarify what you are arguing against.

You can alleviate op rod instantaneous inertia imparted to the carrier and its influence on camming by elongating the cam pin path, like LMT already did on the Enhanced BCG for SOCOM, which the Army refused to allow SOCOM to adopt since it would cause short-stroking if someone installed that carrier in the M16A2/A4.

The Germans did this when they copied Stoner's AR18, but added a longer cam pin path for carrier retraction before unlocking, then FN copied that bolt carrier and bolt with the FN SCAR.

The problem with that route is that the carrier can accelerate without any camming friction, which increases carrier velocity.

Then you have to increase spring rate, which increases carrier return stroke, which increases carrier bounce, which then needs more spring or buffer rate, and now you're in a vicious cycle.

This is why the under-sprung AR15 with bumper pad for return stroke inertia works so well at a behaved balance, with a cascading reciprocating mass with the buffer weights.
