Sure looks like a GenII... the markings say "Multi" ... and I believe that was from when the lower was also purposed for the 6.5CM.
Grip wise... the Hoge should fit as well... and the Magpul on there is a
MIAD GEN 1.1 Grip Kit – TYPE 2 ...
note the TYPE 2 ... that version fills the gap ( up at the curved part ) on PSA PA10's.
If... by chance the hand grip is to fat... I have some PSA branded spare ones ( that you could have ) that are much narrower. They are basic black, with grippy surfaces.
Not sure about the middie Magpul hand guards... but I would suspect they would work.
Is that a rifle length stock ? I am not familiar with that version to know for sure.
I suspect it is a "carbine length" buffer tube under it.... if so, be sure to check for all the correct parts... ( Photos help a lot )
PSA has used 2 different "pattern" .308 carbine buffer systems... and the parts do not interchange, so take some photos and measurements so we can be sure you have the correct parts installed.
This thread will show the differences and measurements.

There are numerous ways to make your PA10 softer shooting and numerous tweaks to help you enjoy it even more.
