| When I pull on the charging handle, all seems to work fine. But when I break the rifle open the buffer and buffer spring prevent the rifle from opening. I have to release the forward take down pin first. I find the buffer retainer pin in the trigger assembly area and its spring over in there as well. Why is it doing this, is something missing? Shot fine the last time I was at the range. Finished cleaning it awhile back, so I double checked my reassembly and I see nothing out of place. (Stock Stag Arms) |

Your receiver extension tube most likely isn't screwed in far enough. Press the buffer retainer down into the hole and screw in the receiver extension until it is holding down the buffer retainer but not so tight that it is binding against the center post. Make sure the buffer retainer can move freely up and down by pressing on the center post.
