You can get bases like these (Williams base, from Midway) that you can screw on. These dovetails would use the Williams type globe (slide on from front rather than side)
I haven't found any globes that don't have dovetails. (Williams and the Lyman 90(?) go front to back, Lyman 17 go from side)
I've never seen one for a .920" barrel. I thought about using those and sanding it down (wrap sandpaper around barrel and then "lap" the base to the barrel...) but would raise the sight too high.
If you have a cheek riser and/or don't mind having your sights tall, the Nodak Spud
NDS-23 (near bottom) is removeable with 2 set screws and would be high enough to use a muffler from your Honda Civic as a suppressor
Of course it won't give you that "target" globe sight (which is what I want)
If you want a low cheek weld with a standard stock you have to cut into the barrel (or use the Tech Sight dovetail adapter. I was nervous about holding it on with "threadlocker", but it seems pretty darn secure).
Even the lowest Globe (ie. the Lyman 17A that is 0.404") would require pretty high rear sights particularly once you add a mounting base (if you didn't cut a dovetail into the barrel and mounted on the surface).
I'm going to post on rimfirecentral details of mine once I get it all worked out. It should be MUCH easier to do (ie
why the hell don't the barrel makers give the option of a dovetail on the target barrels??????)
I will have a Lyman 90 MJT rear set about as low as feasible, with an 17AHB front. It should clear a suppressor fine (as I mentioned above, at least my planned suppressor is barely wider than the bull barrel)
