Check the listing for details. LifeCard Optic Mount. Condition: New. Listed at 16.99 USD. This mount lets you put an RMSc footprint red dot on your LifeCard! So far I've only tested with the Sig Romeo Zero, but I suspect it would work with any red dot with the same footprint. If you're like me then you probably think the stock "sights" leave a bit to be desired. This improves the LifeCard by letting you mount a red dot on it! It also makes the pistol easier to charge, especially for kids, or anyone who thinks the LifeCard is kind of difficult to charge 100+ times in one afternoon. 3D printed in PLA+ Adding weight can affect how your pistol operates. This piece directly mounts to the bolt. If you have a heavy optic it may not reliably fire. Please take this into consideration before ordering. If you do have a heavier optic, one option you have is to not use the included screw. It's not really necessary anyways and just adds weight. Installation is not very difficult. You just snap it on and tighten it up by screwing in the included screw. See installation video (once uploaded) for more tips.
