Very sturdy. definitely minamalist. - SIG SAUER Minimalist Plus Folding Stock for MCX/MPX

Originally, I had the regular minamalist with the smaller butt pad. I purchased this one to use with longer upppers. The design is deffinitely minamalist. The locking mechanism is sturdy. The movement from folded to open requires a little bit of use before it becomes satisfactorily smooth. By design, it is a bit short and is not adjustable. That is an acceptable concession to the compactness of the design. The slotted design makes a great base structure for building up a paracord cheek rest.
