When it comes to maintaining or upgrading your AR-15 rifle, understanding the right size of components is crucial. One such component is the clevis pin. This small but essential part plays a significant role in the functionality of your firearm. In this article, we will delve into the details of what size clevis pin you should use for your AR-15, considering various factors and providing you with the necessary information to make an informed decision.
Understanding the Role of Clevis Pins
