The CMMG HD Pivot and Takedown Pin Set (brand part no. 55AFF3B) replaces the factory pivot and takedown pins on a .223 Remington/5.56 NATO AR-15 with a heavier-duty steel set. CMMG machines the pins from steel for added strength over a standard factory pin, which matters on a rifle that sees frequent takedown for cleaning or maintenance. Because they are a direct fit for the AR-15 platform, installation is a simple pin-for-pin swap with no additional fitting required. It is a straightforward upgrade for anyone who wants sturdier hardware holding their upper and lower receivers together.
