You're missing the detent for the rear takedown pin retainer.


This guide helped me put together my OLL. Skip towards the bottom of the assembly (I think 2nd) post.

Ok I'll bite, The thin spring (Detent spring) is for the rear takedown pin. It goes in the little hole at the rear of your lower, Don't forget to put a detent pin in before the spring. The fatter spring you are holding, goes in the hole of similar size, in the threads, the buffer retainer goes on top of said spring to retain the buffer tube, tighten your buffer tube down till it just stops this pin from comming out..

I am in Lakeside, If your close I can help you with this.

Novice removal of the buffer tube, invariably results in the destruction of the detent spring....no, it should not have that little bend in it. You need a new one.

Most likely, the detent itself is still inside the receiver.

The buffer retainer is held in place by the buffer tube...which is why you found it flying across the room when you unscrewed the tube.

Don't forget to re-stake the retainer ring when you torque it all back together, or you'll just have to do it again.
