When the Aimpoint Acro C-2 first came out it was supposedly a “commercial” pistol model at a lower price, but now their website is listing the Acro C-2 as a new model optimized for carbine use and with a 2.5 MOA dot instead of a 3.5 MOA dot as before.
I have a couple of Acro P2s on Glock handguns. A solid choice in my opinion.
Just sharing….
