Not a tie down screw nut a piece of steel screwed to the bottom of the barrel a few inches in front of the action The .375hh I just bought has one. Just wondering if it was factory original or added later.

Anybody have the dope on this? Thanks

Also looking for a set of used iron sights for it. .550” approximate hole spacing for rear sight. One screw hole for front sight. Yes I put an ad in classifieds
