Product Details
This upper receiver is a solid, no-nonsense choice if you're building or upgrading an AR-15. The 10.5-inch barrel keeps things compact and handy without sacrificing reliability, and it'll run both .223 Remington and 5.56 NATO ammunition. The MLOK handguard gives you plenty of room to attach accessories if you want them, but it's equally good left clean and simple. It's the kind of dependable part that'll just work.
