Trigger from the "enhanced" LPK is nice, and cost no more than the standard LPK from most places. Additionally, there is the "no grip" option along with the option to add the Ergo grip (I'd order anyway) for $2 off...
The barrel has a MOA guarantee if using the Hornady SST ammo. And was dirt cheap (one half to one third the price of others I was looking at). Also got a 556 barrel w/ a MOA guarantee but that's for a different week....
Side charging upper lets me keep using the muscle memory the FAL has built over the years.
Just need to decide on optic... either take off sights and use a low power variable or keep 'em and add a red dot.
