Possible to mount a port buffer and scope mount on HK91 at the same time?

[Golden Hound]

I have an HK91 (if you want to get technical, an SAR-3 overstamp - Greek-made) with an ejection port buffer mounted upon the grooves on top of the receiver. Were I to buy the claw mount either the ARMS mount, the Hensoldt mount or the low profile rail mount, would any or all of these mounts fit on the rifle along with the port buffer?

Yes. It works.
