FAQ

Is this a complete upper receiver assembly?
No, this is a stripped receiver set. It includes the bare billet upper and lower receivers. You will need to install all internal components, barrel, handguard, and stock to complete your firearm.

Yes, this billet lower receiver is designed with a threaded hole for a bolt catch roll pin, making installation significantly easier and more secure than with a standard punch-and-hammer method.
