Flux Defense Raider 365 Ultralight SBR Stock Arm

The Flux Defense Raider 365 Ultralight SBR Stock Arm is a go-to upgrade for the Raider 365 Ultralight. This SBR stock arm is textured and opened up for more surface area, and it comes with a removable rubber buttpad that absorbs more recoil and provides a grippy texture for better shoulder purchase. Fits Raider 365 Ultralight. NOT compatible with aluminum Raider 365. ALL NFA RULES APPLY. Attaching an SBR stock to your chassis will convert it from an FCU into an unregistered SBR.
