Boom is correct; the issue mount is the QRP. Reason? It's cheap, it does the job they need it to do, and it was easy to source from the same manufacturer as the optic itself.
Just don't kid yourself into believing it's the best option. It's probably not even in the top 5. I would choose mounts from ARMS, KAC, PRI, or LaRue before I considered the QRP for my own rifle, but all of those products cost more and have been developed since the QRP was developed, allowing them to improve upon the QRP in various ways, depending on the configuration you need.
IMO, the ARMS #22M68 is the best mount going, and the fact that it is the only mount that is modular, and can therefore be configured to acommidate any common configuration is a huge advantage. Plus, I really like the throw-lever QD ability.
