Hello, I bought a beat up mke sp5 a while back from a feller who included a bunch of other misc mp5 parts.  One of the parts that was included was a standard a2 stock but it has the standard sling attachment point on both sides, rather than just the one with the holes for the pins on the other side.  

Has anyone come across one of these before? Just curious as to its origin.  ..Oh, and it would suffice it to say that I'm super new to roller delays.  Thanks in advance hk friends.

sorry, ETA... Should have also mentioned the stock has no defining marks on it that I could find.

My Coharie Arms clone came with a stock like that

These are / were made in the USA by somebody.

Being a lefty that likes the A2 stock, I asked on the HKPro forum if anyone knew where to get one, as I knew they existed.  This is the only response I got.

I have a MM one that just has the one side... but I'm a bigger fan of single-point with the smaller gun.

I sent mine to Rose Action Sports, who did this...

Interesting, thanks guys.
