In more niche terms, gun rights have seen good progress on a national level.
1. The FRT (forced reset trigger; for those unaware, a "machine gun" is a gun that fires more than 1 bullet with a single trigger pull. An FRT forces the trigger to be "unpulled" before pulling it again, making it technically by the letter of the law, not a machine gun) being functionally legal is a huge step. While it does stand on very shaky ground legally, by the time any hammer comes down to ban it, the "common use" clause gains substantial power due to how popular and in wide use they are. Additionally it helps push the overton window as the general public sees that the not-a-machine-gun that most people have isn't really causing a rise in crime.
2. The ban on import of "machine gun barrels" ending has made the builders hobby far cheaper, and is a step in the right direction. Machine guns cannot be imported, but if you cut up the receiver, its just a bunch of parts, and legally can be imported. Bush 1 decided that if you made a gun with those parts, and used the barrel, that would make said gun a "machine gun" regardless of the capabilities describe in point 1. This has been overturned, making those kits far cheaper to build, as a barrel is a minimum $100 extra to your build. It marks a step in the right direction of freeing up import restrictions on such arms.
3. The big one. The Big Beautiful Bill included that short barreled rifles (a gun with a stock, shooting a single projectile, with a barrel length less than 16"), short barreled shotguns (a gun firing multiple projectiles with a barrel length of less than 18"), supressors/silencers, and any other weapons (basically anything oddball that doesn't look like a gun) reduced the tax cost from $200 per gun, to $0. This not only offers immense potential to move the overton window, it also presents a unique legal arguement. Legally, if a tax costs $0, its not a tax. Not a big deal on its own, but the supreme court has decided several times, that gun registries are forbidden, and that the NFA registry is acceptable because it is a tax registry. You can see the obvious problem here. Big potential for the future.
