A sight with increased zoom for your weapon.
No benefit to doing this.
most marines use a EOTECH holographic sight or a TRIJICON ACOG sight usually around 4x32 - 6x32 magnification
reflex sights are used for more cqb and medium to short firefight as a acog is more attuned to longer to medium firefights both are useful as a reflex sight gives you a more accurate ads where as you might have to hit someone alil longer the acog will be more useful cause it magnifies x4 the distance to hit someone more accurately at longer distance
Red dot, grenade Launcher, FMJ, or an ACOG sight.
An ACOG (Advanced Combat Optical Sight) is commonly equipped with machine guns and assault rifles. Though ACOGs were originally used for the M16 they have been designed for other guns as well.HOPE IT HELPED
Yes you can. If I am understanding your question properly then yes. Just go to the gun that you want to change the sight to and go to attachments. There you can choose ACOG, Red Dot, Infrared, and more.
acog definitely
Yes, use the warlord perk (two gun attachments on the primary weapon).
Buy what you want but here are some suggestions. the SMK 6x36 35mm dayscope, red dot laser aimer, bipod, susat sight, acog sight, red dot sight and finally if you have £15,000 to spend, a BW thermal scope.

well it all depends on style and skill, but most people would prefer the SCAR-H with ACOG scope and the grenade launcher with urban or digital camo with the bling pro, hardline pro, and commando pro 2. or the famas with ACOG sight and grenade launcher with bling pro, stopping power pro, and commando pro 2.
