.350 Legend / .450 Bushmaster Feed problems Solved?

I know what I saw and repairs it. Calling me a liar is a character flaw on your part and that's not on me partner!

I never said you were a liar, I said you were incorrect. If you legitimately think you’re right, but you’re actually wrong, it means you are incorrect.

For instance, if you make up your own step in the cycle of operations, not willfully but simply out of ignorance, you would be incorrect.

I’ve got many character flaws, but this particular instance ain’t one if them.

I knew you would chime in. Your nose is so brown I can smell it from here.

The ejector will depress down in the bolt lower than the bolt face. If the bullet went into full battery it would have simply depressed the ejector and there would have been no hang up. The base of the cartridge never got parallel to the face of the bolt. It was at an angle and the rim was shoved up against the side of the injector causing the round to hang up at an angle. Now what I had an extractor problem it was as you described it simply wouldn't go in you know within a 1/8 of inch or so because the extractor wouldn't slip over the rim. But in this case you could clearly see part of the bolt and that the cartridge was at an angle and being pressed towards the right side of the rifle. There were deep dents in the casing as a result.

Yeah you can go into another thesis on the operation of the AR but I was there and you were not. To even assume that you know what I saw and what I repaired is not possible is a narcissistic and ridiculous. You need to get off the short man syndrome and just take somebody for the word sometimes.

When I took the bolt carrier out of the gun and placed a straight edge on the top of the bolt you could clearly see that the ejector was sticking up past the boat lugs. It was getting hung up on that part that was sticking up too high. It did not do it every time but it did do it every so many rounds that it was a problem. I simply took the ejector out took a little bit off of it to bring it down just below the end of the bolt and never had a problem since then I still have the gun.

I've been working on machines since I was 8 years old. My father was a Maytag repair person and he did that after his regular job. He used to take me on the jobs so I could squeeze in behind the appliances and do the work for him. By the time I was 10 I could take a Maytag washer and dryer part and put it back together again. So I've been working on things for over 40 years. I once saw a a whole pair of underwear in the drain hose of a washer. They have screens and small holes to prevent that from happening. Now how did that happen? I have no clue into this day if my father was alive we would still be scratching our heads wondering how in the hell that happened. Machines sometimes do crazy things and I've seen things that defy logic. Sometimes they just do it and we can explain it. I've seen it in appliances, I've seen it in engines and other car systems and I've seen it in weapons. I've worked on more machines and probably 95% of the people walking this Earth. And I still don't put anything past a machine messing up or doing something unexplainable.

Please. Keep going.

I'll take your word when you are consistently correct. It ain't happened yet.

.....and once again, what you are describing is a CHAMBERING issue, and not a FEEDING issue. If you want to eat at the table with the adults, you have to talk like one. This includes calling something what it is, and not what you made it up to be.

AR's ain't washing machines, and ammo ain't underwear.

Feeding​

As the bolt carrier group moves rearward, it engages the buffer assembly and compresses the action spring into the lower receiver extension. When the bolt carrier group clears the top of the magazine, the expansion of the magazine spring forces the follower and a new round up into the path of the forward movement of the bolt. The expansion of the action spring sends the buffer assembly and bolt carrier group forward with enough force to strip a new round from the magazine.

Chambering​

As the bolt carrier group continues to move forward, the face of the bolt thrusts the new round into the chamber.

Locking​

As the bolt carrier group moves forward, the bolt is kept in its most forward position by the bolt cam pin riding in the guide channel in the upper receiver. Just before the bolt locking lugs make contact with the barrel extension, the bolt cam pin emerges from the guide channel. The pressure exerted by the contact of the bolt locking lugs and barrel extension causes the bolt cam pin to move along the cam track (located in the bolt carrier) in a counterclockwise direction, rotating the bolt locking lugs in line behind the barrel extension locking lugs. At the same time, the extractor claw grips the rim of the cartridge, and the ejector is compressed.

The rifle is ready to fire.

Firing​

With a round in the chamber, the hammer cocked, and the selector on SEMI, the firer squeezes the trigger. The trigger rotates on the trigger pin, depressing the nose of the trigger, and disengaging the notch on the bottom of the hammer. The hammer spring drives the hammer forward. The hammer strikes the head of the firing pin, driving the firing pin through the bolt into the primer of the round. When the primer is struck by the firing pin, it ignites and causes the powder in the cartridge to ignite. The gas generated by the rapid burning of the powder forces the projectile from the cartridge and propels it through the barrel. After the projectile has passed the gas port (located on the upper surface of the barrel under the front sight, Figure 4-5) and before it leaves the barrel, some gas enters the gas port and moves into the gas tube. The gas tube directs the gas into the bolt carrier. It passes through the key downward into a space between the rear of the carrier's bolt cavity and the rear of the bolt itself. The gas then expands. The bolt is locked into the barrel extension and unable to move forward, and the carrier is thus forced to the rear by the expanding gas.

Unlocking​

As the bolt carrier moves to the rear, the bolt cam pin follows the path of the cam track (located in the bolt carrier). This action causes the cam pin and bolt assembly to rotate simultaneously until the locking lugs of the bolt are no longer in line behind the locking lugs of the barrel extension.

Extracting​

The bolt carrier group continues to move to the rear. The extractor (which is attached to the bolt) grips the rim of the cartridge case, holds it firmly against the face of the bolt, and withdraws the cartridge case from the chamber.

Ejecting​

With the base of a cartridge case firmly against the face of the bolt, the ejector and ejector spring are compressed into the bolt body. As the rearward movement of the bolt carrier group allows the nose of the cartridge case to clear the front of the ejection port, the cartridge is pushed out by the action of the ejector and spring.

Cocking​

The rearward movement of the bolt carrier overrides the hammer, forcing it down into the receiver and compressing the hammer spring, cocking the hammer in the firing position. The action of the rifle is much faster than human reaction; therefore, the firer cannot release the trigger fast enough to prevent multiple firing.

I was looking at this thread wondering if I misdiagnosed my .450 AR problem. Not only did I get confirmation on my assumption, but also got to see a full fledged pissing match!
