Bare AR-15 stripped upper receiver — the flat-top starting point for any 5.56 / .223 / .300 BLK / 300 Blackout build. It ships without a bolt carrier group, charging handle, forward assist, or dust cover — just the stripped upper — so you can outfit it with the exact BCG, charging handle, and handguard your build calls for. Flat-top 1913 Picatinny rail runs the full length of the top.

Features:

• AR-15 stripped upper receiver (mil-spec dimensions)
• Flat-top 1913 Picatinny rail on top
• Ships bare — no BCG, charging handle, forward assist, or dust cover
• Compatible with any mil-spec AR-15 barrel nut, handguard, and BCG
• Drops onto any standard mil-spec AR-15 lower

The upper receiver is non-serialized and not FFL-regulated — it ships like a normal part. The lower receiver is the serialized component on an AR-15. Pairs with a mil-spec barrel nut and a standard bolt carrier group for a straightforward build.
