Paul-the new guy Posted October 19, 2018 Share Posted October 19, 2018 I have an 8moa railway plastic C-more on my MPX. I Changed my load from 124FMJ's to 115FMJ's because the guy I bought the 124's from sent me 115's. They are a bit hotter and were hitting about 3.5" high. I loosened the lock screws to bring it down and I cant get it where I want. The zero seems to move all over even the windage has changed... I have had several C-mores and have not had this issue in the past. Scope is tight to the base and the base it tight to the receiver. Any ideas? Link to comment
Xanatos903 Posted October 20, 2018 Share Posted October 20, 2018 Does the ammo group well in between adjustments to the scope? Link to comment
Paul-the new guy Posted October 20, 2018 Author Share Posted October 20, 2018 Got it, seems like the up and down is super sensitive and the side to side is not. Link to comment
Paul-the new guy Posted October 20, 2018 Author Share Posted October 20, 2018 Also seems like the lock screws affect zero Link to comment

stick Posted October 21, 2018 Share Posted October 21, 2018 Paul, Make sure you tighten the lock screw after you make your windage and elevation adjustments. From what I've seen with my C-mores, The lock screw will adjust zero. That's why I always tighten the lock screw after making my adjustments. Once you're where you want to be, ensure the lock screw is tight. Link to comment

Also seems like the lock screws affect zeroYes to both of these. It is a bit challenging to zero these compared to other red dots. But it is not terrible.

SJMPCC022 Posted October 21, 2018 Share Posted October 21, 2018 I just bought a C More railway this week and put it on my gun yesterday. Match tomorrow, all went well with sighting in, we will see what happens. I do know you have to watch the lock screws on reflex sights, sometimes they move the dot a bit when you tighten them. I have not found that to be true with mine. I was debating between a Holosun 510C and the C More. End of the day, the C More is lighter, stupid bright and have been mounted on open guns since the decade of the 80's. These sights have 30 plus years of great history. You may have a rare bad one, the warranty is a good one. Link to comment
