Got oil?
This rifle looks bone dry to me.
This rifle appears to be using an old G.I. 20 round magazine. I gotta wonder about the condition of that magazine. The failure appears to be from an over ride.
This sort of jam is common with the AR15 type mechanism. I think we had to drop the magazine, separate the halves, pull the bolt out, then fish out the round. With an open top design all you would have had to do is pull the bolt back, tilt the rifle for the round to fall out, and let the bolt go forward and feed the next round.
I have had blown primers in the AR, so have others. Shoot enough hot loads in your AR, primers will fall down and jam up the mechanism. When crap gets down into the lower, gets trapped between the hammer and sear, the gun is down. It takes punches to knock out the trigger mechanism.
Now the various variants of the M16 weigh as much as an M14, so the weight advantage is gone.
When I talk to Gulf War Veterans, these guys are having to clean their M4/M16's at least three times a day. In Vietnam, one Company Commander I knew required his troops to clean their M16's at each rest stop. About every hour!
The M14/M1 Garand mechanism I don't recall anyone ever talking about having to clean it. I remember one Korean War Vet, he out and said that no matter how dirty his Garand got, it fired and functioned perfectly.
n Army testing the AR10's barrel burst when a bullet exited halfway down the barrel. IIRC, and I am looking for confirmation, this happened after 5,000 rounds. The fault was thought to be not because of the composite style barrel but because of the stainless steel 416 alloy’s lack of durability over a wide temperature range, susceptibility to cracking due to high sulphur content, and the barrel heat treatment could have been better. Armalite replaced the barrel with a conventional steel barrel. Before the barrel change the AR10 was 6.85 pounds compared to the T-44 (M14 prototype) at 8.45 pounds.
One of the major sources of reference for US Rifle M14 was an unpublished manuscript written by Lt Col. Rayle, entitled Growth of a Rifle, wherein he recalls the interesting period of the Armory's dealings with ArmaLite as follows:
..In the fall of 1956 I received word that the Armory was to conduct a test of a new light rifle, designated the AR-10 which had been developed by.Armalite..We at the Armory had not seen this new rifle, but had heard of it being demonstrated at Fort Benning and Fort Monroe. The ArmaLite engineers had visited us some time earlier, but on other matters then the entry in the light rifle program. They had come to discuss new sporting rifle barrels they had been working on made wholly or partly of aluminum, both for advice and to see if we were interested in testing one such weapon. We felt that military rifles had high energy levels at such rates that they would not hold up made of aluminum, even with the latest hard coatings. However we expressed more interest in a design involving a steel liner with an aluminum jacket. I had Dr. [Alexander] Hammer review this design for strength and accuracy ona theoretical basis, considering both heat and pressure. the design was somewhat similar to other composite designs we had considered. The design was found feasible, and could save perhaps half a pound in weight, but the barrel would be more expensive to make. We expressed interest to the extent of offering to test such a barrel in a commercial action under an arrangement where we would pay them $1.00 for the rifle, then in effect test it for them free of charge.
We were soon paid a visit by Mr. Dorchester, designer [!] of the AR-10 to lay out a plan of tests. This gave us out first opportunity to examine the [AR-10] rifle in detail. [It] weighed about 7 1/2 lbs., being about 1 1/14 lb. lighter then the T44. The light weight was achieved mainly through the use of a foam filled plastic stock and a composite steel and aluminum barrel. More weight was saved by eliminating bayonet and grenade launcher features. The weapon was gas operated, with the gas bled back through a tube and introduced to a space between the the rear of the bolt and a bolt carrier, where gas pressure could supply energy to perform the functions of unlocking and reloading. The general idea of a gas system of this type was also incorporated in the T31 rifle, the last rifle John Garand worked on before he retired. In order to reduce the sharper recoil forces that would come from a lighter rifle firing the NATO cartridge a muzzle brake that looked something like a small can was used, and the rear sight was incorporated in a carrying handle. A 20-round box magazine was used, and in general, the rifle appeared to be designed to meet many of the objectives we were seeking in a new light rifle for the Army. A tentative test program was drawn up, based on the same type tests used with teh T44 and T48 rifles. Mr. Dorchester requested one minor modification to the test and we agreed. Mr. Mel Johnson was retained by ArmaLite in the capacity of consultant to help insure the conduct of a fair, impartial test. Mel had severed his connections with Winchester, and was a free lance consultant at that time.
Testing of two rifles [serial nos. 1002 and 1004] began in mid December, but was soon stopped due to early failure of the muzzle brake/flash suppressor. Other problem areas included extractor breakage, sear failure, failure to feed, pierced primers, stubbed rounds, failure to eject, and warpage of the gas tube.
Early in January, 1957, the ArmaLite representatives returned with the modified prototype rifles, ready to resume tests. The muzzle brake was now made of titanium instead of aluminum, and the gas tube was made of 4130 alloy steel instead of stainless steel.
The first day or two we spent checking over the rifles again, weighing the weapons, having ArmaLite representatives go over the changes made, and finalizing the test program. We allocated one rifle [ser. 1002] to durability testing and the other [ser. 1004] to general performance testing..[which] showed the gas tube warpage had been corrected. Recoil and muzzle blast were both under excellent control with the stronger, redesigned unit, although as testing proceeded, fouling began to occur and flash was no longer properly suppressed.
Tests under frost conditions and sub-zero temperatures revealed malfunctions which had not appeared in ambient testing. Also, we noticed that the rifles left overnight without complete cleaning had a tendency to freeze up from the effects of residue on sliding surfaces, and had to be jarred loose.
After only a few days of testing we ran into a much more serious problem. We had not yet reached the most severe part of the test schedule, when a bullet came out the side of the barrel just ahead of the hand of the gunner holding the rifle. Naturally, this stopped the test. Our metallurgists were called in for investigation of the barrel material. It was learned that the steel liner, under the aluminum jacket had been made of stainless steel, alloy type 416. Our experts advised that stainless steel of this type might possibly be satisfactory in a water cooled gun, but for an air cooled barrel operating over a wide temperature range, it would not have sufficient transverse strength properties. Furthermore, the high sulphur content, included to facilitate machining, caused sulphide stringers to occur where cracks could start and propagate. They also found that the barrel heat treatment used could have been improved for this particular application. We had developed through extensive research, a good military barrel steel of a chromium-molybdenum-vanadium alloy type, which withstood rather high barrel temperatures without rupturing. Stainless steel has very poor hot hardness properties compared to this alloy.
Mr. Dorchester learned of some of the excellent work Dave Mathewson in New Haven had done for us on the T44, so he approached Dave for assistance. Dave had some T44 barrel blanks on hand, and together [he and Stoner] worked up an all steel barrel design for teh AR-10 as light as the original composite design by the technique of milling long slots or flutes in the barrel, in effect creating longitudinal stiffening ribs. By calling some of his model makers to work overtime, Dave completed fabrication of the barrels over a weekend. Early the next week Mr. Dorchester was back at the Armory with the AR-10s now equipped with the new barrels and anxious to resume the tests. Before resuming tests we examined the design in detail, and checked it out theoretically for strength. Our calculation indicated the design was safe to fire, and the testing was resumed. This time the testing was completed without further serious incidents, but a number of malfunctions were recorded. We were being urged by the Pentagon to complete our report and send it in, so by the end of February [1957] the report was finished. The ArmaLite engineers freely expressed their feeling that they had been rushed into this test prior to a chance to really work out many of the bugs in the rifle. Apparently Fairchild could see the Army was on the verge of selecting a new rifle and felt they should immediately submit the [AR-10] for Army tests. The report could do little more then record the various troubles we had experienced, and indicate that in it's present form the rifle was not satisfactory as a military service rifle.
Jeff White - The M14 was a complete failure. It couldn't be produced on the Garand machinery and we never built enough of them to equip the entire force.
The M14 was a complete failure because we were unable to mass produce it. It was production difficulties that caused McNamara to abandon the program. It never performed the mission it was designed to perform, that being the standard shoulder weapon of the U.S. armed forces because we were never able to produce it in sufficient quantity to accomplish that mission.
Ash - Complete failure means an arm failed to perform as designed or in some way or was defective in design or in operation. It was superseded by the M16, but that was in no way due to a failure of performance in the M14.
The point is the M14 was replaced not because it could not perform the mission to which it was designed, but because the US was following the Soviets in going to an intermediate round.
Slamfire1 - Things I like about my M1a: the open top design allows you to quickly see and clear a malfunction.
Ash - The AR-10, on the other hand, was a complete failure.
No doubt about it the M14 was mass produced and enough were made to arm soldiers needing rifles.
Never made enough to equip the total force. How many units had MTOEs that called for M14s but still had M1s as a substitute item? Virtually the entire reserve component for one, low priority AC units for two, several hundred thousand of those rifles went to the USMC and I would guess at least 10,000 went to weapons pools at training centers and branch schools. We never had enough of them to equip the total force. Don't forget in 1965 we gave the M16 to Airborne, Air Assault and Special Forces units. It was the standard service rifle on paper, in reality we never produced enough of them. To me that makes it a failure. It was replaced before we could build enough of them to equip the force. And one of the reasons McNamara shut it down was the problems we had producing it.
But, the M16A2 did in fact equip all of the units authorized it before it was replaced. The same cannot be said for the M14.
I think it took about 17 years from the time the M16A2 to be fielded throughout the total force and about 2 years later the Army adopted the A4 as standard for Infantry units that didn't get the M4. The long time to field the M16A2 was a budgeting decision, not a production problem. The M14 was not fielded on schedule because of production problems.
Yes, there were production problems with the M14, the same is true with the M16 and many other U.S. Army rifles, but I think it has been shown in this thread that production problems alone did not doom the M14's issue to all troops. I am well aware of those production problems from my reading of U.S. Rifle M14: from John Garand to the M21. You don't think I find so much stuff to post just from my memory do you?
BTW, while the Mini never served as an infantry arm, it did at least see widespread civilian use as a rear-guard arm in prisons, police units, and the A-Team.

If I am staying in one location I take the M14. At 55 mobility might be my biggest weakness. I think you have to consider your personal limitations in the decision of these two firearms. I am still pretty accurate at long distance. At my age I take the M14.
Those are all uses that an inexpensive, light carbine, that is politically correct in appearance, and not intended to be used in engagements where hundreds of rounds will be fired is a good choice.
To be fair, Minis are built as a commercial gun. The design and action are proven, it's just the construction that lets it down. It's like how you wouldn't expect a DPMS to be a combat rifle, even though the AR design is more than capable of that.
As an aside, I don't know what a military-grade Mini would be like, but it would probably be pretty cool.
That poodle cartridge worked really well on all the poodles we shot in Iraq. Though they were strange looking poodles. They walked on their hind legs and wore clothing.The .223 is a fine varmint cartridge, suitable for prairie dogs, woodchucks, coyotes, and small poodles. When and if the zombie poodle apocalypse ever arrives the U.S. armed forces will be well armed.
