Ive been fitting my Lane reg to my S410 as well. Fitting is fairly straight forwards if your not bothered about getting the drill out. Getting a close setup is probably 3 dismantles if youve watched the videos. Although getting it spoton has been another few strip downs as well and I'm not there yet. I wish I'd had the bottle refilled before starting as it was only 180 to start with and frustratingly it's down to 125Bar now
Which is still 37 shots down to 75Bar on a .22 rifle running the original striker and the replacement springs with the transfer port opened to 3.5mm and restricted slightly ( probably ~0.5mm but not measured ) by adjustment screw.
But, swapping to a Diablo Field they get a bit too close to 12PDS for my liking so still some tinkering to be done and I'm thinking the striker probably needs a shave also.

Edit. Striker lightned down to 34 grams with the bushes fitted and transfer port restrictor opened fully... a couple of Diablos fired for curiosity and came out at 11.48 and 11.39, so hopefully on the money without any more fettling required.
