Product Details
This is the upper receiver part of your AR-15, meaning it's the top half that holds your barrel and bolt carrier group. It comes fully assembled so you don't have to fuss with tiny parts, and it's made by Ruger, a company that's been doing this for decades. If you're building or upgrading an AR-15 rifle or pistol, this works with standard AR-15 pattern lowers. It's a solid, no-nonsense choice.
