Bought a pair of BKL 566 risers 11mm dovetail to 20mm picatinny, to put NV on an AA s200.
In the instruction leaflet it states if too tight remove clamping screw, fit into the threaded hole on the mount and tighten so as to widen the width.
However, the gun dovetail is 11mm and the mount dovetail is 13 mm, the exact opposite.
So, am I expected to decrease this 2 mm by really tightening the clamping screws ? The mount is machined from one solid piece, so would it give or snap ?
Never come across anything like this before, and it seems odd that it tells you how to widen but not decrease the width. Surely for a well known and respected item it should fit in the first place anyway.
