PTR 91 Mount

[Rich78]

I have a PTR 91 and purchased the standard claw mount which attaches to grooves on top of the receiver. I have a SightMark holo sight which fits perfectly. However I want to add the SightMark 5X magnifier. This is were I run into problems. There just isn't enough room on the picatinny rail to mount both. I searched HKPARTS.com and found a full barrel length rail but it is out of my price range ($250 for a rail is absurd). Anyone have any ideas? I was thinking of getting another claw mount and trimming it down and lining both rails up together. Another idea was to mount a long picatinny riser to the claw mount but that would place the optics higher than I want. Any ideas would be greatly appreciated
