Get both from Rock Solid Industries.
I have their bolt handle & scope base on one Mosin, and liked the handle so much I had one put on a Mauser variation.
I don't feel the slightest bit guilty about chopping up a Mosin.
Mine was cut back to a 22-inch barrel, Duracoated, re-stocked with a Boyds, and the rear sight removed.
It'll never be worth anywhere near what I put into it, but it's a fun shooter & now one of my favorite rifles.
It certainly has its own character.
