Why not require semi-auto rifles to be modified to fixed magazine weapons in all future sales.

35. I don't believe this is possible. A gun owner can correct me.

First of all, you would need to require an outright redesign of the gun to work this way. The manufacturers would just stop producing them. You would just create a boom for the existing weapons market.

Also, thieves would be in their glory. The price fetched for a stolen AR-15 just quadrupled. It's now that much more worth it for thieves to steal them.

Since a rifle is a tool, tools can be taken apart and refactored. People convert guns all of the time (example: semi-auto to full auto).

Doing the changes to the magazine would be useless. Manufacturers could just create custom magazines. It doesn't matter how illegal they are - a black market would exist for them. Knowledgeable gun users could circumvent this.

Do the changes apply to cops as well? If not, those guns can be stolen or "stolen" if you know what I mean. If not, they'll be outgunned by people with illegal assault rifles. The classic assault weapons ban problem still exists.

There are many more issues. If I was inaccurate on anything, a gun person will probably correct me. These are some things to consider.
