If you're using a McKay Enterprises receiver -- do not buy this item. I tried and tried to install this rivet but whoever manufactured this part did a terrible job at actually giving you any material to actually deform/mushroom in order to make the rivet. Way, WAY too short.
After several hours, I found a bolt in my shop that was about the same size, cut it to the length I needed with a dremel, drilled it and then tapped it. Works perfectly! And far more secure than this one would have been as I was able to deform plenty of material to form the rivet.
I definitely do not recommend,it was way more frustrating than it should have been. Buy a bolt! It's cheaper and works better.
