I could be wrong, but every m1a I've owned would run with more carbon in da plug then that. I think there just messing with u spike.

Have u looked at gas port alignment, loose piston or op rod alignment? I'm curious about those 3

Keep in mind that the military didn't issue drill bits. You cleaned the piston with a bore brush and the plug with a chamber brush. The piston tail stayed clogged until M16 bore brushes showed up.

Hey guys I'm back in not going to quote everyone and reply individually.

When I first got in the army one of my first guns was a m14 ebr. So I'm familiar with it. All they told use to do for cleaning was to wipe the chamber down, clean the bolt face. Run a boresnake through it. Every now and then clean the piston tail. DON'T ever take apart the gas system because they would send it in to get cleaned.

I'm not going to take my mount off to test if it's the mount or not. I just zeroed the damn scope at 100m within a moa. It never had a problem till recently, so it's not the mount.

My guess is that the plug got to full of carbon to fully complete a cycle. Because it was failing when the bolt was riding forward. I would have brass caught between the bolt and chamber. I just ran 2 full mags through it in my living room (obviously on safe and not shooting) and it ejected just fine. So next time I shoot it will be the real test.

The piston is damaged at the front probably because of all the harden carbon in the plug, so I just bought a new better one.

And lastly you dont need to baby this weapon. Its not gas like a m4. You don't need to clean it Every time you shoot it. If my issued one could go through sandstorms for multiple months, and still send rounds down range I'm sure my civilian m1a can go just fine in normal conditions.

Your issued weapon always ran because your armorers aligned the gas port, fit the op rods, cleaned and lubed, and replaced parts that were out of spec. I hope I didn't or am not still challenging your knowledge. I read all that in the 1st post, and knew you humped the weapon, so I figured you had field maintenance down pat, which I'm sure you do. Other than the clean the pig advice the other tips are more advanced than field maintenance. I learned a lot from reading Gus Fishers post on this forum, he covers about everything the armorers would do to these weapons behind the scenes, check it out

I don't know about any others , but we used long shank tweeker type screwdrivers for cleaning the gas piston and tails. Gas piston was removed often and checked for carbon. Even in boot camp, we took it apart for cleaning.
Same with the bolt. Part of the cleaning regiment.

I will say I don't clean my rifles every single time I shoot them, and no, these things don't have to be babied, but God knows I'd hate to really need a rifle to function, and then have it fail after a few rounds.

Spike, you were issued the EBR? I guess that means you were better than the average shot?? Rockin'!
