The Rotor Clip A-300 Hinge Pin Clip Tool installs the small A-300 retaining clip that secures the ejection port cover’s hinge pin on an AR-15, a fiddly job that’s genuinely difficult to do reliably with generic pliers. Rotor Clip, the manufacturer of the A-300 clip itself, built this tool specifically to seat that clip correctly without deforming it or launching it across the bench, a common frustration when attempting the job freehand. Getting the clip seated properly the first time saves the aggravation of chasing a tiny spring clip across the shop floor. Stock it with the rest of our gunsmithing tools and gunsmith supplies for AR-15 build and repair work.

Frequently Asked Questions

Why is the A-300 clip so hard to install without this tool? It’s small and spring-loaded, making it prone to launching or deforming under uneven pressure from generic pliers rather than a purpose-built seating tool.

Does this tool work with other AR-15 hinge pin clips? It’s built specifically around the Rotor Clip A-300 design, so results are most reliable with that exact clip.
