While looking into the oil question I posed earlier, I found quite a few people complaining that the adjustable windage design was not reliable.
The main complaint seems to be the screws coming loose under heavy recoil, but no one that I've found has said it has happened to them, just that it is a concern.
Has anyone else seen this when used on .308 or similar calibers? - I have no idea whether this is classed as high recoil!
Might be a little late for me to be realising this as I have already ordered some, but it's still nice to know all the facts!
