The question you need to ask yourself is what is the role and distance your shooting ?? For me I prefer a full size RDS, easier to acquire a target and most are zeroed at 25 and some at 50 yds.
It’s just a fun gun and 50 yards would be max distance. The better question is do you find a specific size POA like 6 moa more efficient at getting POA and target together? I can see where a full size RDS would be preferable.
My competition PCC rifle has a C-More with a 4MOA dot. It is very fast. I have messed around with Aimpoint, Vortex RDO as well as LVPO and the fastest for me is the C-More followed closely by a holosun.
I am old and half blind. I love the Holosun 510C but the dot is too small (for me) for USPSA PCC. I am now using a 6 MOA Alpha as the main dot and a 6 MOA Viper at a 45 degree offset for hard left side leans. My steel challenge 22 rifle has an 8 MOA C-More. Ask 10 shooters and you will get 10 different answers. That said, there are some damn fine GM shooters using 2 MOA dots for everything. When they want bigger and brighter they turn the brightness up until the dot "blooms".
I use this....red or green but it's a prism scope etched onto the glass. I don't even turn it on most of the time. Works well even if you have glasses.
