That little fella one one of my first prototypes, a solid sheet steel charging handle with a 3d printed plastic "handle". It has worked awesome over the years, I figured it might wear the upper out too much with hard use, but definitely wasn't the case. I was going to do a group buy or something with them, but they take a lot of manual work to round out all the edges that need to be rounded; so i figured it wasn't worth it.
I'm not sure what brand of stock that is, but an HK factory stock should have THIS stamped into it:
So definitely NOT an HK factory stock.

So it could be an Airsoft.... (The B&T stocks usually have a flatter top than the rounded top... and much better finished) although worst case, as long as it fits into the stock hinge, it may work. The USC doesn't have much recoil so it's not going to fall apart....
Although it does appear the guy may not have been honest in a lot of these things...
I'm yeah its definitely not an HK stock. Not too sure what to make of this.
He didn't even include the stock roll pin so I can't really see if it does in fact attach and line up or not yet.
Time will tell and then I will go ahead with what my cousin who's a cop suggested
