Product Details
This is a complete upper receiver that drops right onto your existing AR15 lower - no gunsmithing needed. It's a 12.5" barrel in 223 Remington/5.56 NATO with a gas-piston system, which means it runs cleaner and with less recoil than standard push-rod setups. What makes it special is the flexibility: it takes standard AR magazines, belt-fed M27 links, and those big 100 or 200-round SAW drums if you want them. Comes with 100 M27 links to get you started.
