Love your posts, although most of the time I have no idea what you're talking about. I can just sense the depth of knowledge behind your remarks, and that seems to make it all worthwhile.
Those Anschutz sights are just pure mechanical p o r n!
But, to my inquiry....Of the available options, Williams FP-AG, TS1 and Gehman, which would be your recommended best option for the new FWB Sport? Years ago I used to have an inexpensive Mendoza air rifle with a knock off Williams peep sight mounted. I think I might have been shooting more accurately with that gun and sight than I do now with far more expensive rifle and scope options....... and younger eyes. I'm just not sure that my eyesight is good enough to get on with a peep sight these days.
Cheers!
Thank you sir! Yes, I tend to be overly wordy in my posts - please don't ever hesitate to call me out, or ask questions!
NOTE: I've never laid hands on the new FWB Sport, so everything following could be WRONG!
BUT...looking at photos of it, I'd guess the scope rail spacing is the same as the old FWB 300 match rifles - which is a bit WIDER than 11 mm. In my experience, Anschutz sights WILL NOT FIT, without some damage to either the sight or gun. So your options are:
1. The Williams FP-AG.
2. A Mendoza sight, if you can find one. These have a much sturdier mount than the Williams, but are no longer made, and you are stuck with their own eye disks which use a unique thread.
3. The TS1, but the base won't fit the wider FWB rails. You'd need to move the main body to a scope ring. Which might cause issues with a low front sight, I don't know.
4. Best of all would be...Feinwerkbau's own diopter, as made for their old match rifles. The shallow transverse grooves between the Sport's scope rails are actually for the retaining bolt on these sights (which also acts like a scope stop - as Bear-of-Grayling noted - to keep the sight from moving).
There were two variations of these sights. Either will work. (NOTE the earlier "interference" type bolt must be screwed ALL THE WAY OUT when taking the sight on or off, and you must be careful to line it up with one of the transverse grooves. Otherwise it can ding up the finish.)
