I really wanted to use the more player model mod but ​I'm locked in version 1.21.4 the more player model mod allows you to switch your avatar's and also gives you the ability to turn in to any mob (plus some modded mobs) and allows players to sit,crawl and lay down it also has some other features but these are the main ones

The research I done say that the fp5 filter is NATO while the gp5 is gost how is this filter able to work with the gp5 while other NATO filters don't work?
