Need help identifying an AR upper reciever

[smokey308]

Just picked up a 6.5 Grendel and I am trying to find out who makes the upper receiver and as of now this is the only marking that i can find. Just thought someone here have seen this before.
Thanks

So I posted in some other places and come to find out it was made by Shadow Ops Weaponry which was a company out of Colorado but they are no longer in business.

Thanks all for looking

That appears to be marked on the charging handle and if so, it may be an aftermarket add on...Not necessarily the manufacturer of the upper...I have had several uppers of unknown origin that had various aftermarket parts installed...

Since the Shadow Ops company is out of business, you may have an impossible time making a positive identification...
