Rush Posted May 26, 2004 Share Posted May 26, 2004 Just wanted to ask around on people's experience with the "Railway" version of c-more. Its on a single side mount on a STI frame.... What's irritating about this c-more is that it won't stay zeroed! I zero at about 20 yards... so adjust adjust... turn a screw here and there until I consistently hit a 1" group at about 20. So I tighten the adjusment screw locks.. shoot off two groups of 5 rds and...... the darn things "zero" has moved away. I loosen the adjustment screw locks, fire another 5rd grp and it shoots back at its original "zeroed" position... What concerns me is if I keep the adjusment screw locks loose (a) I'll constantly have to zero the gun ( I'll loose the lock screws somehow... Is this a warranty issue with C-more? Can I get a replacement? Never had this problem with the "Serendipity" models before... Thanks in advance... Kind Regards Link to comment Share on other sites More sharing options...
ErikW Posted May 26, 2004 Share Posted May 26, 2004 Nah, it has nothing to do with the fact it's a Railway. They are all the same sight with the same adjustments and adjuster-lockers. Seems to me this has happened before and been discussed here. Maybe you should try a search. Link to comment Share on other sites More sharing options...
ong45 Posted May 26, 2004 Share Posted May 26, 2004 When you adjust the windage, don't loosen the lock screw. It is unneccesary and affects the zero when you retighten.Not so for elevation though.Good luck James Link to comment Share on other sites More sharing options...
Rush Posted May 26, 2004 Author Share Posted May 26, 2004 Thanks EriK, Ong... Just tried the search (",) .. sorry bout that.... I'll be abit more "proactive" next time... I normally loosen all the lock screws... I'll re-zero with just the elevation screw and leave the windage lock screw alone. Its never happened before with the serendipity model so I was surprised when I tested the new open. It had two different aim impacts in two days... Regards & Thanks Again.

B.J. Norris Posted May 26, 2004 Share Posted May 26, 2004 Might also want to check the body of the sight really close to make sure its not cracked. Link to comment Share on other sites More sharing options...
Rush Posted May 27, 2004 Author Share Posted May 27, 2004 Thanks. I'll re-zero today under the new "procedures" (",).. Glad to know the c-more ain't broke though.. relieved... so i'll loosen the elevation locks and keep the windage locks snug... Thanks again...

Jon Merricks Posted May 30, 2004 Share Posted May 30, 2004 I have been having problems with my elevation not staying zeroed. The lock screw on the side would loosen in less than 50 rounds. I took the screw out then sprayed some pro grip on it and it stays put even after adjusting. Do this at your own risk not to sure if it could mess somthing up.

Ross Carter Posted May 30, 2004 Share Posted May 30, 2004 You may have some parallax problems too. Put the gun on a rest pointed at a target about 20 yds and without touching the gun move your head around and see if the dot moves on the target. If you have a bunch you might contact Cmore.

Rush Posted June 15, 2004 Author Share Posted June 15, 2004 Hi Ross, I'll test for parallax problems as you recommend. didn't know about that one and I was thinking it was purely a elevation and windage adjustment problem. I've re-zeroed the sight at 16 meters. So far, its holding its zero. For consistency, I checked the groups against a board and then a 4 x 8" plate at 30 meters.
