I saw this at the NRA Exhibit hall in Louisville. It’s a Mark II, Mark III quick change barrel system. You can swap out barrels in about 2 seconds with this. Want a 4″ barrels instead of a six inch? No problem. Want a suppressed 3 inch barrel? No problem. Might be handy if you do multiple shooting disciplines.
Wow, that’s ideal for me. I love my MkIII, but having to get the barrel/receiver permanently threaded for use with my suppressor is annoying.
I occasionally travel back to California (gasp!) and often bring my MkIII to shoot with old friends. However, if it has a threaded barrel, it magically becomes an “assault weapon” and is prohibited. Go figure.
It’d be nice to have a threaded barrel and non-threaded barrel for different uses.
Very cool indeed.
I have an older version of one of those. It’s called a “High-Standard”.
And I have a modern version called a “Browning Buckmark.” It takes more than 2 seconds to unscrew the hexhead bolt that holds the barrel in place, move the sites, etc., but I can live with that.
Because the Ruger’s barrel assembly is the serialized part, you’d have to buy the initial M2QC receiver through an FFL. I never could figure out why Ruger did it that way.
