FAQ
Is this a complete rifle?
No. This is a complete upper receiver assembly, one of the two main components of an AR-15. You must pair it with a legal lower receiver, a bolt carrier group, and a charging handle to have a functioning firearm.
What does “No Assembly Required” mean?
It means the barrel, gas system, handguard, and rail are already professionally installed and torqued to spec on the upper receiver. You do not need to install a barrel nut, gas block, or align the handguard. Simply attach it to your lower and add the BCG and charging handle.
