I have said this before & Ill say it again.....
As long as you are shooting corrosive ammo it is an iron site gun.....
There are no mounts that will allow mounted optics to remain mounted/stationary during the regular cleaning. Since you will always have a changing POI (every time you shoot) it is useless mounting optics unless you dont clean after that czech ammo.... which means RUST in the barrel and gas system. Which means your accuracy will be zippo either way....
Save your cash - be practicle, call a spade a spade
Dont mount optics unless you are shooting non-corrosive ammo....
