Review on High-Quality Prime Line 9187527 Slotted Spring 25 Pack for Ultimate Versatility and Durability by Ryan Lawson

These spring pins are ideal for Mil. I was able to install this with my puncher on the bottom of the Stag Arms with no problem. Just be sure to apply a small drop of oil or grease before inserting the pen. The fit and finish is exactly the same as your typical overpriced "Mil-Spec" cleats that you'd pay ten times more for. Keep a few and sell the rest. You won't regret it.
