There is a general issue that plagues all 1x optics to varying degrees with some being worse than others - they are all too bright.
This leads to an overblown reticle image, paired with a secondary artifacting in which the reticle is surrounded by a ghost-like halo, further distorting its clarity. I am unsure if this is related to the brightness issue or to some UE5 Anti-Aliasing side-effect. This is somewhat visible in the screenshots but due to compression it's less clear than in game.
The second issue relates specifically to the optics using single red dot reticles including the M68 CCO (USA), T-2 Micro (PMC) and Z-Point (GFI). In the case of the first two they should have a 2 Minute of Angle (MOA) sized dot however they appear to have significantly larger dots, even without the brightness issues. When paired with the above brightness/ghosting issues it combines to create an oversized reticle that becomes essentially useless past 100m as it completely obscures a target.
For a 2 MOA dot reference look at the Yoloson Micro RDS (4th image) and the size of its centre dot. This should be the size of dot for both M68 and T-2. Technically, the Z-Point in reality has a 3.5 MOA dot but for consistency and useability reasons this should be standardised to 2 MOA. General brightness should also be decreased across the board. A smaller and finer reticle allows for more versatility if required to engage at ranges exceeding 100m but within 300m.
Note that all holographic sights have a 1 MOA centre dot for reference.
Pictures show comparison of most (forgot the VDV 1p87 Holographic) 1x optics in game aimed at the chest of a human-sized-target at 150m distance.
