M11/9 SMG Upper help, need pic

[rustyolddog]

I need to know if a SMG M11 upper receiver is made different than a semi auto version. Receiver only, I know the bolt & fire control is different. If someone could post a pic of the underside of their M11/9 SMG upper receiver without the bolt, I'd appreciate it.

My selector is wearing on my upper and it seems odd, like the upper should have a notch cut for the selector.

Thanks.

Hope this helps.... There are several relief cuts....

That was off of a M11/9 SMG....

Thanks Brian, there appears to be a slight relief at the top receiver edge in the photo approximately where the chamber is located. Is this correct? Other than that, mine look the same. No point of wear from the selector on yours either. Thanks again.

I am not the best with a camera but here is the flip side....
