Convert Your C-More Serendipity to a Slide Ride
by Bob Londrigan, published in Front Sight Magazine, January 2007
Let’s say you have a well functioning C-More Serendipity scope. However, one of mounting holes has cracked…or you want to mount it to your new AR…or you simply want to switch over to a single sided mount. These are just a few examples of why you might want to convert your C-more Serendipity scope into a Slide Ride or even a Railway mount type of sight. You could send your Serendipity off to C-More, and they would replace the case for about $65 plus shipping. Or, with only a few simple tools and about 10 minutes of your time, you could do the conversion yourself. If you choose to do this yourself, then read on as I explain how it is done.
First, assemble the tools necessary for this job. You will need:
|Start by cutting the legs off the C-more with your hacksaw.
Don’t cut them too close to the actual body -- leave about ¼ to 1/8 inch of the
legs intact as you will trim them up later.
|After you’ve cut off the legs, it’s time to drill some holes. On the underside of the scope toward the front, you will see a 3/16” hole. This hole is underneath the part of the scope that holds the lens. Using this hole as a pilot, drill upwards through the part of the scope that holds the lens. Keep the hole square with the scope and make sure you don’t hit the portion of the scope holding the lens. For this step, it works well to hold the scope in a padded vise. Be careful not to apply too much force as you may crush the case.|
drilled this hole, flip the scope over and drill down through the top with a
5/16 drill bit again using the 3/16” hole as a pilot. Drill only
through the top layer and not through the bottom.
Important: Be careful while drilling this hole, because after you cut
through the first layer, the drill will grab and want to go the rest of the way
through. You are drilling this 5/16” hole as clearance for the head of one of
the 10-32 cap head screws that will hold the scope to the mount. Do not drill
all the way through the bottom section. You need the smaller hole in the bottom
section or the hole will be the same size as the head of the screw, and you
won’t have anything to hold the scope to the mount.
|Once you’ve drilled these holes, remove the cover from the bottom of the scope that covers the electronics. Use the picture for reference to locate the three slots on the back side of the cover (towards the inside). Insert a knife or small blade into one of these slots and pry up the cover. Now take off both the battery cover and the piece that holds down the dot module and set them aside.|
|If you look closely at the circuit board, you will see that it is held in with two T-8 torx screws. Remove the one furthest to the rear of the scope. It is the one that comes up in between the dot module and the battery.|
|Once you have removed the torx screw, drill a 3/16” hole from the bottom side using the screw hole as a pilot.|
|Now it’s time to trim off the remaining portions of those
legs you cut off earlier. It’s best to use a belt sander for this step. Go
slowly and make sure the bottom of the scope is square. Otherwise it won’t sit
straight on the scopemount/railway.
You are now ready to mount your scope to the scopemount or Railway plate. You will need two 10/32 x ½ inch socket head cap screws. Screw the scope to the mount and then check to see if the screws stick out of the bottom of the scopemount/Railway. If they extend beyond the base, grind them a little shorter and try again. Once you have them the right length, dab on some blue Loctite and screw them down.
Replace your battery cover, replace your dot module cover, and you are done. Now all you have to do is decide to which gun you want to attach your new C-More Slide Ride scope.
