Turns it to a very powerful mid range semi-auto marksman rifle

This is how vanilla M16a2 looks - really great. You can even don't bother with adapter rail, just make "hide" selection for it, and hide it with the help of script when is attached to M16A2, plus dedicated slot "weaponOpticsAcog" is already created. Please, think about it, looks really great. P.S It's acog X6 (not x4) that has hide selection, means you were plannig it (or thinking about it). It's a really nice idea. Maybe, in 2023 you'll go more with a military weapons, instead of civillian. Nice alternative for SVD on .308 would be cool (like some semi-auto .308 marksman rifle, M14 DMR, or M110, or SR25). You can limit it with the x6 acog scope, so the bolt-action snipers will still be top of the tier (m700 and savanna). I don't concider LAR as an alternative to SVD, it's more close, a little bit mid range weapon. Anyway, thanks for reading, think about it and have a nice day. Good luck with 1.20

PPS. Acog x6 would be too big for it I think, x4 is just right, compact and looks cool on it
