Nice red dot for the hellcat - OpticsPlanet Exclusive Swampfox Sentinel 1x16mm Ultra Compact Micro Red Dot Sight

I have the auto brightness version of the Sentinel for my Springfield Hellcat and have really enjoyed using it. It is very dim in the complete dark but otherwise the brightness has been good and the auto brightness adjusts nearly instantly. Ships with a rubber protector over the red dot, which is really for shipping/storage when not on the gun. I used a razor blade to shape it so that it fits the Sentinel when on my hellcat (which is where it should be living all the time) so now its a nice protector when I store my gun for travel. I had an issue with the glass after a couple months and Swampfox was true to their (essentially) lifetime warranty: I sent it back to them and they sent me a new one and it has been running great since in about a week. So for all the reviews that had issues, Swampfox is very responsive and have a lifetime warranty (50k rounds, technically).
