I must say that I am baffled. I also have an 11-87 and have never had a problem with it. could be a few things...if you take the forearm off, there is a sticker that shows the order in which to put all of the parts back on when you put it together. It is very important that all parts (espesialy the o-ring) are precisely in the order shown. Not having these parts in the right order is going to account for 99% of any ejection problems. I would replace the o-ring for good measure. hope this helps
