I am not sure as to how ideal this optic is for the VZ58, but I recently acquired a vortex spitfire 1x (prism optic, like acogs) and have been very impressed.

Regarding CP's last post -- the 3x version it has rails on the optic to allow for a 1x optic mount...

Back to the 1x:
-the recticle is etched so in event of battery failure you can still have a point of aim unlike red dots (excluding backup irons -- why I really like cowitnessing red dots on the VZ58)
-it weighs 11.2 oz (per spec sheet) with mount and battery vs 3.7oz aimpoint micro and riser for same height (~3 oz) puts it at ~7 oz, so ~4oz heavier
-4" long vs aimpoint micro at 2.4"
-there is an ocular adjustment wheel which means w/ less than perfect sight you can adjust the optic to make the reticle crisp
-has both red and green illumination vs most red dots w/ just one color
-does not have an illuminated setting low enough for night vision -- but you can do the old trick where you close the front cap and with both eyes open, it allows minute of man aiming at cqb ranges... And yes, you can use nv on the eye that's not the optic... Not ideal, but would work.
-it does have caps for both front and rear.
-and vortex also has a killflash for this optic as well (important for me as 1) it protects the front lens and 2) kills flash
-battery life, vortex at 250 hrs max setting and 2000 hrs lowest setting, vs aimpoint t1 at 50,000 hrs min and bushnell/primary arms micro dots at 1000 hrs mid setting and 3000 hrs lowest
Overall pretty impressed, some give and take as always with weight and battery life being primary downsides for me. Adjustable focus and etched reticle being primary pluses.
PSA currently has this on sale at $199 -- everywhere else is ~$260 to $300 on it.
