I forgot about this problem. I shot it a few weeks ago and i remember putting it away because when I put in a new mag and hit the charging handle it felt very wrong. So i was able to get the cartridge out and i put it away... was going to go shooting right now and when i picked it up I heard a rattle :rolleyes: and i remembered there was a problem.

Started to take it apart and it was obvious.

Although the Buffer retainer doesn't look odd, i think im just going to order a new on thinking the tolerence may be off?... and of course i need a new spring.

The question is... Is this a problem i should be worried about? Im not very experienced with AR's and am more of a pistol guy but this seems like a fluke?

Any input would be appreciated :o

About the only way the spring & retainer can get out of it's pocket is if the buffer tube is loose and unscrewed itself out of the lower far enough to let the spring & plunger escape.
Or it wasn't screwed in far enough to start with when the gun was built.

Check that out good when you put it back together.

SO its the buffer tube that holds it down? I thought it was the buffer itself then when the carrier came back it retained it down?

The only spring that even looks like your spring is the buffer retainer spring. Are you sure your buffer retainer is working? The only other place a spring like what your are showing is from the trigger sear but it's not as long and is smaller in dia.

If the threaded end of the buffer tube is screwed back out too far, the spring & plunger can fly out as soon as the buffer moves back into the tube during cycling.

Like yours did.

The plunger should be captive at all times, even when you take the buffer out for cleaning.
