Just bought a Optima V2 and getting around to setting it up for shooting and hunting next season. I am sure that it will exceed my expectations in most areas but I have a couple gripes. The supplied durasight mount seems pretty stout but I like a lower scope and a qr type system. Almost NO ONE makes a decent base for these rifles other than Durasight. It's like they are proprietary to those, that's not good! Second is the swivel loops/studs. Uncle Mike's swivels are the industry standard and you can't even get them on!! I am sure the "Claw" swivels fit perfect, again, proprietary! Not sure but CVA owns both companies or they are in bed with them. When it comes to accessories, I should be able to use what I want and not be forced to use what they want me to use! I am sure if they come up with a way that there barrels only shoot Powerbelts they will do that too! At least they listened and offer another BH for Blackhorn 209.
