IMO...
1 all of the FAL's i have owned [two SA 48's, one FN, one L1A1, one steyr parts rifle] liked 147/150 grain ammo better than heavier match offerings. they all seemed to prefer federal AE308 [american eagle] over other flavors i tried in them.
2 learn to use the grenade firing setting. eliminates the need to change gas settings when trying different ammo for accuracy.
3 i feel a 1x4 with heavy duplex reticle near ideal for them. the heavy cross hair is an impediment to accuracy, but a big plus in low light conditions. the illuminated reticles are a double edged sword. in marginal light with a barely visible target, your pupil will close due to the extra light, and you'll loose the target. as noted by another poster, it's not a target grade rifle. but i have had one that would shoot 5 rounds into nearly MOA so i feel glass a worthwhile accessory. get one with a low # as close to a true one power as possible, and learn to shoot it with both eyes open. much faster target acquisition. there will be time to go 4x for further targets. adjust the iron sights before installing glass, and get rings that will be quickly/easily removed in the field in case the glass goes T.U. at exactly the wrong time. the DSA mount is rock solid, but a pain in the crevice for cleaning operations, yet another double edged sword.
4 handle/fire other's rifles to find out what mods you may want. what you like may be different from them. that's why there are SO MANY variations out there. fr'instance i like them without the carry handle. as such, i would prefer the non-cut receiver you have for extra receiver rigidity.
5 as noted above, forget the bbl mount bipod. accuracy WILL suffer from using them.
6 this rifle will work with ball ammo for the most dangerous species out to about 600yds, where it starts running out of steam pretty fast. memorize your trajectory/hold over to AT least that range if you install a non-BDC optic.
7 milsurp 7.62 is quite a bit hotter than SAAMI .308 winch. gas settings WILL need adjusting when switching between the two.
8 congrats, you picked THE battle rifle from many other very good offerings.
