A solid choice - Gideon Optics Mediator Red Dot 16mm Reflex Sights

Seen plenty of Yt videos on this particular model, and can confirm it’s reliable well built rugged RDS , being an enclosed emitter is a huge advantage as dirt rain etc can’t get in and cause issues with the emitter , plus it looks pretty cool with its cuts on the sides. I have the red version normally I prefer green. RDS is bright and visual even in bright conditions could be a little more brighter but overall still good.
