So I m old school. I run an acog with an adm mount 2.0 and flip sight’s underneath…. I have gobs of experience with an acog but am slowly coming to terms with the times and plan on offsetting an aimpoint acro p2. Not sure what mount has a reputation for being stout or mainingting zero well. The arisaka looks ok I’m careful with my weapons and gear, but call it paranoia, but I want my kit to be retard proof and as indestructible as I can manage. I have been interested in the rmr and not opposed to it, I’m not interested in anything from China rds wise but am open to arguments between the rmr and acro. Weight is also a concern but much lower on the list. I’d happily run a few oz heavy for piece of mind. For example I run a spur mount on my spr. Would consider changing acog mounts too… also if anyone can tell me if there’s forward light emissions on the acro or rmr. Like when you are aiming at someone and they are wearing nods…..
