SERPICO

I was trying to decide between the RMR & the SRO since there were pro's & con's for each. I wasn't aware of the RMR HD until now. I just looked it up and it seems like an awesome optic and probably the best for the M4 with the Mesa Reflex Mount. I appreciate your help.

Thanks for letting me know. I'm researching which red dot I want to get and I see you went with the Holosun. How did you decide on that one and does it co-witness with the factory iron sights?

@sukhoi_fan Thank you for the tip!

I'm brand new to this site. This is my first post and I hope I'm posting this in the correct area. Will I be notified if I receive any responses to my post? I'll try not to ask any stupid questions but I recently purchased an M4 and I want to build it out with the accessories that will enhance it the best I can. Does anyone have a Mesa Tactical SureShell Carrier With Reflex Mount for their M4? I'm thinking about adding one to my M4 and was curious how people like it and which red dot they ended up installing on it? I like the idea of the red dot being able to co-witnesses with the factory sights and I was considering either the Trijicon RMR or SRO. Any thoughts or suggestions would be appreciated. Thanks.
