The AirTac Customs Flux Body Pins are here!

We changed the game with our colorful CRBN uppers, but now it’s time to customize the rest of the gun. Welcome to AirTac Customs’ next generation of aluminum rifle parts!

The Flux body pin is our replacement for the stock tension-based pin in any M4-pattern lower. This durable 2-piece screw design ensures that your pins won’t be going anywhere while providing a beautiful CNC accent!
