Yup, that's polygonal rifling. Hills and valleys vs lands and grooves. Just making sure you didn't have some out of left field hybrid.

Yes, you need the rough welded safety to be correct. Here's a link to a popular parts supplier. https://www.libertytreecollectors.co...?idCategory=83
FYI, the late war substitute standard aka last ditch rifles are every bit as serviceable as any other T99. Production steps where curtailed but not the quality of materials.

I didn't know that! So they were made from the same steel but just not finished as nicely?

That also explains why I've thought every nice T99 I've looked at was shot out....lol
