- The vertical struts for the MBA-3 are fixed therefore the cheek piece is not reversible like the MBA-1 however the cheek piece itself is designed with a cheek pad for left-handed use
- Caution: the MBA-3 and MBA-4 Carbine buttstocks are not designed to be used with Large Bore Calibers such as .338 Lapua or .50 BMG applications. See our MBA-1 and MBA-2 Rifle buttstocks as alternatives.
