Like the title says, this compliments my Mepro RDS Pro perfectly. I really like how you can just pull back on it to flip it out of the way when you want to use the RDS by itself. It mounts very easily and comes with a slip-on cover.
What I like about this optic is the quality. It is a bit on the pricey range but you do get what you pay for. It just works. I like the versatility of being able to quickly transition and easily acquire the target at range.
