Ruger mark iv - TANDEMKROSS Tandemized Ruger Mark IV and Mark IV 22/45 Cthulhu Lower

This is a fantastic product. built right out of the box…just add your favorite barrel (volquartsen) And you’re done. FYI, You do lose the quick takedown button. You use a Allen key with locking screw instead to engage the hook . to me, I don’t care if it takes a little longer to field strip . I’m used to the mark 3 anyway. It’s about the same amount of time to takedown. think i like the volquartsen trigger (hammer and sear) better. but i’ll give it some time to break in first.
