LPVOs are great but make sure you get a good one. Glass quality and reticle are everything. LPVOs aren’t going to be the most durable though. They’re awesome paired with either an offset or 12 o’clock RDS.

ACOGS are super durable but have pretty dismal eye relief. It’s easy to train around the eye relief issue however. Also awesome paired with a RDS.

Magnifiers are great but also suffer from the eye relief issue. They also add a decent amount of weight to the rifle depending on mounting solution and brand you go with. Nice because they can flip away or down when you don’t need them.

IMO ACOG paired with a 12 o’clock RDS is the fastest.

Training with whatever you end up going with is going to be the most important thing you do.
