C-More Red Dot

[Joe D]

Looking at going with a C-More Rail for my AR 9mm. Does the dot stay centered in the "window" as you adjust for elevation? I am wondering due to the way you adjust for elevation.

[longbeard]

Generally, your comb height will relate to the view you have through the window. Too low or too high and the dot will be at the top or bottom of the glass due to the angle you are looking through the window.  You can add risers to the rail or comb to control this if need be. You want the mounted gun to give u a good window view.

 

After that, adjusting elevation on the optic itself should not move the dot so substantially that it's out of the field of view. It's adjusted with set screws on the optic. Generally a few clicks to get it dialed in.

I've been running C-Mores for 25 years on pistols and rifles.  The dot stays in the center when adjusted.  On my JP I run it in the most forward position attached directly to the rail and have no issues.

I'm the same as Old3gnr. When I "sight in" I try to keep the dot centered. But when shooting a stage it doesn't seem to matter if the dot is not exactly in the middle. It still hits where that dot is. How that happens is a mystery to me, but it just works. I love the c-more for the unobstructed view it offers.

What size dot do you run? Thanks.

The technical answer would be yes. The layman's answer would be no.

 

If you keep your eye position fixed and adjust the elevation, the dot will move. But it is not moving much, 60 moa is 1°. So visually it doesn't move.

 

With a red dot, you are seeing the reflection of the dot focused at infinity. If you draw a line from the target to your eye, the dot will be where it intersects the lens. If you move you head up, the dot will "move" up on the lens, but still remain on target. If you move your head closer, the dot will "appear" smaller, but remain the same size relative to the target. If you move your head back really far, the dot can fill the lens, but still remain the same size relative to the target.

Thanks for the replies. I actually shot a Chi - More with a 12moa dot the other day. You have to whittle on the module a touch to get it to fit the Chinese copy. Dot stayed centered on his 9mm AR.

I also have run a railway on several guns including my current PCC. Very reliable. No riser needed. I prefer an 8min dot. It is a good size for USPSA distances. 0-100 yds.

[Joe D]

I installed a 12moa dot into my $32 Chi-More sight. Works perfectly.

I have C-mores on all three of my PCC's.  The dot stays centered when you adjust elevation.  When you make elevation adjustments, the housing is moved, not the dot itself.

Scooter said it well. Think of it like a rifle scope. Do the lines that make up the crosshair move? Of course they do.  Is it enough that you will notice it? Not unless you have some really special vision. 

[MLS2GO]

thanks for the info, I currently rude a small dot on my PCC and considering something larger.

I've been shooting an 8moa, but just changed to a 6. Haven't shot a match yet, but I think it will be better.

[Flageo]

I am shooting a c more rts2 with an 8 moa on my ruger pcc     more compact than the railway   i shoot steel challenge with my ruger

I shot my first uspsa match Sunday with the 6 moa. I like it better.

I switched form a 8moa to 6moa o my cmore slideride and I wish I would have done it sooner. Now, all my guns also have 6moa red dots.

[MoRivera]

6MOA on my C-mores as well.

[rishii]

I ran the same 8 moa That I ran on pistols for years and like it until I tried a 4 moa , with the scopes being closer to your face when mounted on a rifle, the 8 moa dot seems huge

[MaX_1]

Running a C-more 6 MOA, good to go with 100 yrds targets,  Click switch is the best option to keep it in the same brightness  

[MLS2GO]

Bought my first C-More an 8 MOA and used it in an USPSA Match today for the first time and loved it.I am excited to try the bigger dot on Steel Challenge too. Previously I have shot mostly a Leupold Delta Point Pro. After a few matches I will know more.

[Shootymacshootface]

It seems like dot size preferences are varied.  I prefer smaller because the C-More is brite enough to compensate. The one thing that I wouldn't put on my gun is the aluminum version. The polymer version is less expensive and it won't get bent if it takes a hard hit. That will ruin your match.

[egd5]

I hope I never find out, but I'd think a hit hard enough to bend the aluminum one would break the polymer one. Same end result though, you're screwed.

8MOA on my two PCC’s And also on my two rimfire rifles
