Product Details
This is a great upper receiver if you're building your first AR-15 and want something reliable without overcomplicating things. It's set up for 5.56 NATO with a 13.7" barrel, comes fully assembled so you don't have to fuss with that part, and the threaded muzzle (1/2x28) gives you options down the road if you want to add a muzzle brake or suppressor. You'll need to source the bolt carrier group and charging handle separately, but we can help you figure out what works for your build.
