Sako Optilock rings, great ‘scope rings, they come with a variety of bases and have polymer inserts so they are aligned without undue stresses on the tube nor fear of marking. Usually found on Sako and Tikka rifles, what is not to like about them? Well very little in fact until you go to replace the screws.
The original Optilock screws are an unusual size and worse still the heads have a reduced diameter so they do not even conform to DIN912 standard which means they are hard to source and expensive as well. This would probably explain why we receive so many enquires for replacement screws. Ours are manufactured from A4 stainless so should last a life time.
These are available in Stainless Steel only and come in a set of 8 and cost GBP16.00 plus some postage.
