- Includes a Picatinny Rail on the bottom rear of the Stock Body to attach your choice of many accessories.
- Designed a flat bottom index set screw (10-24) to eliminate that constant rattle of carbine collapsible buttstock. This also allows you to secure the stock in your favorite position.
- 3-axis adjustable butt plate assembly (keep in mind this butt plate assembly is interchangeable with the original MBA-1 Buttstock) will have the following movement:
- Horizontal for linear adjustment (i.e. length of pull)
- Vertical for a perfect butt plate fit into the curvature of the shoulder.
- Lateral adjustment for a ½ inch left or right cast.
