Re: EGW vs Blackhawk 20 MOA base
One thing to keep in mind, the EGW base does not have a recoil lug, while the Weaver base does, so if the Blackhawk is a rebranded Weaver (which I agree they look exactly the same)then it too should have a recoil lug. Also, some people have shy'd away from Weaver worried that it is not a true picatinny base; however, Weaver claims this base is a picatinny spec base, so you shouldn't have a problem there even though it is Weaver brand.
