Are any of them non restricted? How can there be semi auto shot guns that shoot huge slugs, but not non restricted hunting caliber semi auto rifles like the .300 core rifle? Am I off here?
I don't think it is possible to get the 20 round magazine with the Magpul 5 round blocker. You can buy the magpul blocker from brownells but I am not sure if it would be legal to remove the rivet and use the blocker.
They came with the blocker and no rivet.
I love my Core15, just need to find more time to shoot it!
