The latest addition to our popular line of stocks for the A-5! The new MX4 f/x Stock is six position adjustable, and features tilted butt, rear sling mount and military issue metal slide tube! Don't be fooled by plastic wanna-be imitators! Works especially well with vertical bottle or our Intruder foregrip. Extend it fully for the comfort and extra stability of a full stock, and then collapse it for the in-close, tight stuff.
