Frequently Asked Questions
Does this upper receiver require an FFL transfer to purchase?
No. Under federal law, the AR-15 upper receiver is considered a non-serialized accessory component, not a firearm. It can be purchased online and shipped directly to your door without an FFL transfer.
What additional components do I need to finish a complete upper assembly?
To complete this upper receiver into a fully functional upper assembly, you will need a barrel, barrel nut, handguard/rail system, gas block, gas tube, muzzle device, and a Bolt Carrier Group (BCG).
Can I use this upper receiver for calibers other than 5.56 NATO?
Yes. As a standard mil-spec AR-15 upper receiver, it can be used to build rifles or pistols chambered in .300 AAC Blackout, .223 Remington, .350 Legend, 6.5 Grendel, or 22 ARC when paired with the corresponding caliber-specific barrel and bolt.
Are the forward assist and dust cover pre-installed?
The kit includes the stripped receiver and separate completion assemblies (forward assist spring/pawl and dust cover rod/spring/door). This allows you to install them during your build process or customize them with aftermarket components if desired.
