This is a pack of AK animations that work for first, third and true first person perspectives, in the demo map you'll find 2 character blueprints, one is for true first person and third person and one is setup for first person (arms).
Check video Demo
Third person mesh and arms share the same Skelton so the same animations work for both.
Some example for animations you can find:
Inspect weapon, Mag check, Mag out, Mag in, Mag in then chamber, Walk, Sprint etc
