I want a pivot pin for my SR762, just as displayed in this photo.

That’s a Matrix lower. I’ll have to look it up (maybe @98Z5V has the answer) but I remember there being a few issues with LPK comparability. 

Edit: looks like your good to go. I can’t find anything that says it uses special pins. The pins are about $25. I have similar on my rifle.
