Default Gun Trouble: M4 & M16

Ret'd General Scales asks why:

The rifle that today's infantry uses is little changed since the 1960s—and it is badly flawed. Military lives depend on these cheap composites of metal and plastic. So why can't the richest country in the world give its soldiers better ones?

There over a thousand comments since December 2th 2014, so apologies if you've read the article and engaged there!

There two old threads on US military rifles, so maybe the issues have been vented there:

From 2007 Better than M4, but you can’t have it:

From 2008 The Army’s M-4 Carbine: Background and Issues for Congress:

Default some trouble can be avoided by delay

The need to replace the 5.56x45mm and the M4/M16 was arguably proven and accepted years ago. However such replacement by better performed metal-cased ammunition and weapons has been delayed by the promise of combustible/caseless small arms ammunition. And even after changes at the top it seems the US defence hierarchy has again decided to whittle away more years by continued tinkering with the 5.56x45 and the M4/M16.

That resolve could be overturned by executive fiat but otherwise it seems US forces will just have to wait. Probably for at least ten and possibly more than 20 years until the effectiveness and stockpiling of suitable caseless rounds are thoroughly proven. Compliant NATO and affiliated forces are almost certain to follow along.

Its not an issue as this article would have people believe. Even the issues that do exist could be addressed without replacing the system as a whole.

Ive got to say that some retired officer whose last time in combat was 40+ years ago pontificating about our troops current needs off of what he learned in the Mekong is a joke. The only thing the same about that weapon system and the one we carry on a daily basis is the operating system.

We have weapons that see 10k+ rounds a year and the only thing we really burn is bolts and barrels and sometimes cam pins. These guns are ran hot, suppressed, with high round counts between cleaning.

Most of the issues are maintenance issues that we can address with proper lubrication. These carbines kept wet with a real lube (not clp) run like a top and stay accurate. The rest are mag induced failures.

You want your m4 or variant burn it down on the range and real world? easy..

-Replace mags if they induce more than one failure (that means track your mags regular army. An Okay industries mag from gulf war one is unacceptable)

-Change bolts every 5k rounds or before a deployment if your unit is short on funds

-Use a quality lubricant like slip2000, fireclean or froglube. The army won't buy it? Too bad, be a real NCO and take care of your soldiers. Don't accept mediocre CLP, it might kill you. Keep your gun wet with lube, and a small bottle to add lube if your bolt dries up during extended fire.


As a side note, discussions of lethality are meaningless when rounds don't land on target. Lets face it, most soldiers can't shoot. Actually training past BRM and a few repetitions of ready up drills will go a long way towards showing how lethal 5.56 can truly be.

The real issue is that most of the M4 failures are based on mythology.

Here are some "facts" about OUR experience with M4's on the range.

- Some of our M4's have well over 200,000 rounds down range. Barrels have been replaced, gas tubes have been replaced, BCG's have been replaced but what sets it apart from the AK47's is that upper and lower receivers continue to function. AK's get to about the 100,000+ round count and rails on the receiver will start to crack. It's an easy fix with tig welding but they crack. We have yet to lose an upper or lower receiver from cracking.
The above post, with a quote from the linked thread, raises for me a very general question:

What exactly is reliabilty when it comes to firarms, specifically issued one? Is a gun reliably because you can fire it after a quick cleaning after having been buried in African sand for decades? When it fires in a bitter Russian winter with little care or after it was dropped from a house hitting the pavement?

What is it's relationship with durability, as witnessed in the M4's upper and lower receiver after so many rounds fired reliably?

Overall it seems fairly easy to stack the deck against or for a specific firearm, by using a tailored mix of conditions.

P.S: I wonder how often just the usual wear and tear without proper maintance or replacement parts grinds down the reliability of a weapons system which afterward gets a name for unreliability.
