You must have this as master esp. Install this first, then the optional.
As for my other mod page, you can overwrite this esp over its clone if you also have my patch from there.

Update: Just a quick patch for new Horizon 1.94:
Ammo Set: Now use Horizon Ammo Set of Combat Rifle 30/556/762 for better compatibility and balance.
Already spawn weapons will be affected, so better scrap your gun before updating.
