Luth-AR MBA-3 Buttplate Assy - 3-Axis Black. Machined from Type II hardened tool steel and bead blasted each individual part for a precise fit and lasting finish. The MBA-3 buttplate may be mounted to buttstocks that do not have the 3-Axis capability. Please see the (buttstock manual) link below for the buttstock and receiver extensions that are required for the MBA-3. The stock plate does not have the ability to rotate i.e. it cannot be rotated left or right. The MBA-3 buttplate may be installed with or without the receiver extension. The buttplate is sold separately but it is easily installed with the appropriate buttstock and locking device (such as the Luth-AR Rock Solid Charging Handle or RED DODGED Handle).
