My buffer retainer came loose causing a non-firing condition.  I had taken my collapsable stock off and put it back on. How do I assure that my stock and buffer tube are screwed in enough to "capture" the buffer retainer.  Is there a lip on the tube that overrides the back portion of the retainer that holds it in place?  I did replace the retainer spring if that helps as it was kinked.  This weapon is a Lightweight Colt Sporter circa 1993.  Regards, Bill

the reciver extension (buffer tube) gets screwed over the Buffer Detent.

there are pics in the build it yourself section showing what and how.

Yep... screw the buffer tube over the lip on the dentent but not so far that its against the dentent itself.

Well... my problem is that when the tube is screwed in with the forward lip over the detent lip but back from the pointed part of the detent, the collapsable stock is at the 7 oclock position relative to the rifle (looking from the rear) and the detent can release during firing releasing the buffer, causing a jam.   Turning the stock around clock-wise to regain a six oclock position, the buffer tube extends too far forward and prevents the upper from properly mating with the lower preventing insertion of the rear take down pin.

The buffer tube is a little ragged on the leading edge.  Is is time to get a new tube?  Thanks, Bill

or you can time the reciver extension buy removing material so the extension will sit where it has to in relation to the pin.

FWIW, you do not need that pin in the rifle for the ar to function correctly. Pin's job is to make dissasembly easier.

Thanks Gregory K:  let me make sure I understand...the buffer detent pin is not required to be in the rifle for proper function?  I'm a novice on the design.  Therefore, my rifle jammed because the detent pin and spring popped out of its hole and those loose parts caused the jam.  Interesting, regards, Bill Z.

You got it.

That pin only keeps the buffer from coming out when you shotgun the rifle.  when the rifle is closed the carrier pushes the buffer back a small amount to enusre contact between the buffer and carrier.
