This is free only catch is you must own a USC and are willing to do some minor mill work on this block. I bought this knowing this while I was building my UMP but went on the OG HK UMP stock. Anyways the Adjustments needed are bigger hole for hinge pins and fitted to Lower. I dont have the drum buffer that shows in this picture. FYI this is the block with tube I will be giving.
Im sure their is someone that can use it more that me, That has the time and USC to make this happen. This is not the HDPS C block but a custom "Inspiration" of it.
