I always edit them manually, never bother with 3rd party programs. but glad  you have it sorted

Well, I basically use the site to have the scaffold, then I also look through manually.And it says in it, but you still find them very, very rare

The smgbody is Rare, and the riflebody is VeryRare (the highest in the game, equal to the m249), so that makes sense. Compare it to the total items you have in that container and all of their rarities too. You could change the riflebody in the rarity override option.
