Juicy Media features a custom firearm build referred to as the "MP7 at home," which is a CMMG Banshee chambered in 4.6x30 caliber. The key feature is the integration of the AS Designs ARC Fire system. To get the unique setup to function correctly, the creator had to perform considerable moderate modification and extensive tuning of components, including the buffer system.

During live fire testing, the firearm's recoil impulse was found to be comparable to a lightweight, well-tuned 5.56 AR-15 configuration. The 4.6x30 ammunition is described as a small 5.56 round. The creator's decision to use this specific caliber was pragmatic, as they had a ready supply of the expensive ammunition leftover from a previous project.

Juicy Media determined the build is an impractical item intended purely as a range toy. Despite the demanding modifications to the platform, the CMMG Banshee itself proved to be reliable. Also included is a demonstration and comparison of the firearm's sound signature using various suppressors.
