Stanag 30mm rings
Very well made product. However description did not say may need minor fitting. On my HK G3 mount I had to drill the holes out 20 thousandth for a proper fit. Not a big job however it should be noted that you may have to do minor fitting. Otherwise great product would have had 5 stars.
Valdada answer:
That particular mount, we believe was manufactured some years ago for a contract to Portugal. On that mount, the Stanag wholes are a hair undersized and need a very minor adjustment . Our rings are made to the correct specs, they fit perfectly on all ARMS mounts (#2, #5, #22, etc) and other European made Stanag mounts.
Thank you sir.
