Frequently Asked Questions
Is this a complete firearm?
No. This is a complete AR-15 upper receiver assembly. It is the rifle portion of the firearm. To build a functioning rifle, you must attach it to a legally registered or serialized AR-15 lower receiver, which is the regulated firearm component.
What tools are needed for assembly?
You will need a set of roll pin punches, an armorer’s wrench, and a vise with a reaction rod or upper receiver block to properly torque the barrel nut. The upper ships fully assembled, so you only need to mate it to your lower receiver using the takedown pins.
Does it include sights or an optic?
This upper assembly does not include iron sights, an optic, or a charging handle. You will need to source a charging handle and your preferred sighting system separately to complete your build.
