This is the shortest configuration CMMG offers in 9mm. The threaded barrel allows you to attach muzzle devices like suppressors (subject to NFA regulations). The RML4 M-Lok handguard provides plenty of mounting points for accessories like lights and optics. This upper ships with a bolt carrier group and charging handle, so you have most of what you need to complete a pistol build.
Important Note: This is an upper receiver only. Lower receiver is sold separately. Due to the short barrel length, this upper may require registration with the ATF as an SBR or compliance with pistol build regulations depending on your configuration. Please be aware of all applicable federal, state, and local laws.
