YZY’s Montgo-9 package is a 3D printable lower receiver designed around the Montgo-9 upper receiver from MatadorArms. The Montgo-9 upper receiver is a monolithic upper receiver for AR-platform firearms, using standard 9MM Glock magazines and does not require the use of a buffer tube.

This lower-receiver was heavily remixed from RKSpookware’s UBAR9 lower receiver for AR-9 variant pistol-caliber carbines, which was
remixed from IvanTheTroll’s AR-15 UBAR receiver and uses geometry from Not_SpookyGuns’ AR-9 Firebolt platform.While the Montgo-9 can be installed directly onto RKSpookware’s UBAR-9 package without issue, this package removes much of the redundant buffer tower reinforcements that are normally required for firearms that necessitate the use of a buffer tube.
This package has also been overhauled aesthetically and features an extended mag-release for easier reach. It also removes some extra hardware that is necessary for front-takedown pin reinforcements found on the UBAR models.

A special thank you to MatadorArms for supplying this upper receiver and publishing the .STEP file – without them, this package would not have been possible.
