Glad you found it informative! Fitted my Hawke 3-9x40 scope to the Weihrauch using the two-piece mounts it came with, and reset the parallax from the stock (and useless for air rifles) 100 yards to around 25 yards, which I'll properly set when I'm at the range. There's a recoil-arrest pin which has slotted nicely into the middle divot on the action, but I could probably still do with replacing the mounts with a one-piece when I get a chance. I've also ordered some bits to improve the stock moderator (it's nothing more than than a spring and some felt, so I'm going to add two baffles and the insides of a pair of plastic hair-curlers) along with a ½" UNF thread adapter. That screws onto the built-on moderator in place of the end-cap, and then I can attach an additional moderator for even more muzzle-blast reduction. I'm going to pick up a Deben Whisper 130, which isn't the best moderator around but is pretty cheap and is only 13cm in length so it won't ruin the pointability too much - and, 'cos it's ½" UNF, I can just unscrew it when I value a reduction in length over a reduction in noise. Should make the rifle overall the same length as my AA S410 with its AA silencer. I've also got my eye on a Bisley adjustable butt-plate (snigger), but it needs some modification to fit (grinding down and a new countersunk hole drilled) and I'm cack-handed, so I may just stick with the stock stock butt. Wouldn't mind a sling and swivels, though, and at least that's just drilling one hole ('cos the other swivel attaches to the underlever, which has a far more positive locking mechanism than the TX200's). Going to the range tonight (if it's open - I've just remembered it's a bank holiday) to zero the HW97K, then I'll need to go again on Thursday to zero the AA 410 now it has the shiny Hawke 4-16x50 AO IR on it. Oh, and I'll be using new pellets: 15.9gr RWS Super Fields, rather than the 14.5gr RWS Superdomes I used to use. Heavier and without the pinstriping on the skirt, so I'd need to re-zero even if I hadn't switched scopes. Picked up the same in .177 (8.4gr) for the HW97K, 'cos I heard it likes heavier pellets. At some point I should probably pick up a selection pack and do some proper testing to find out the favoured diet of both rifles, but for now these'll do. Oh, and while I was shopping: I picked up some of those Auritech Shoots recommended up-thread, to see if they're more reliably comfortable than the Napier Pro 10s, a Tipton Gun Butler to make cleaning and maintenance easier, and an air-rifle-specific breech flag so I can stop using the red cable-tie I'm currently shoving in there!
