Nice set of Pins......although

Posted by GARY GWILLIAM on May 7th 2023

Trying to finish the build of an AR 10 and finding a set of Pins that fit has been an obstacle of enormous proportions, and now going on well past several months. These Pins were the correct diameter, and the takedown Pin was also the correct length, even including the added shoulder for the retention pin. The Pivot Pin, again was the correct diameter, but in this case the added shoulder for the retention pin was at a diameter that was way out of limits to allow full passage through the Lower Receiver. Without the added shoulder, this Pivot Pin would have fit exactly leaving it flush on both sides. I have 1 alternative option and thayt is to file down the shoulder to the 0.25 diameter of the rest of the Pivot Pin, and then re-drilling the retention pin hole where I need it. Have not gone that route yet.

Better buy a spare set because your buddies are going to lose these too. But seriously these were just what I needed when I damaged my spring.

These are simply too short for the AR10 receiver.
