Good concept, lacking for my needs

It's a cool concept but the execution could have been done a little different in my mind. I do like the construction of the forward grip surface that allows a stabilization hand when prone long-distance shooting is needed. But when it came to clearing rooms, I need something closer in like the fully collapsible stock. The cheek weld was also something that was lacking in its execution as it did not have a set screw like the shoulder does. Overall, it's not a bad design, just not a good one for me. I did end up ordering another stock from AT3 which works perfectly for my needs.
