I own a 1943 bolt-action Mosin-Nagant. IF I was to upgrade the stock to one of those new ArchAngel stocks, it goes from clip-fed to magazine-fed.
How does a change of stock, with no change to the action of the rifle, make it an “assault weapon” ???
My mosin-nagan is finnish.
The usual work around in CA is to install a bullet-button magazine. That is what is routinely done for AR-15 type weapons.
Another approach would be a device that held two (or more) magazines, each 10 rounds, with provisions to switch the feed from one to the other. 10 round magazines are permitted, and there is no limit on how many of them you can have.
Are the mags reliable? The genius part of the MN is the Nagant designed mag that takes pressure of the lower rounds off the upper one.
