Not doubting your word a bit Pete. What was that good reason for using the short version? Mine, CODFan's and 3or 4 others I've seen photo's of have the wrong ones so I'm curious as to why and how they got there.
If fact I'd just as soon do away with it altogether since you say it's incorrect and replace it with the standard No.4 flush fit guard screw if possible. As long as I own mine it will be used for nothing but hunting and the loop will never be utilized for it's intended purpose so it's more of a hindrance than a help.
