Any reason you want an ak pattern over an ar pattern? An ak that shoots 5.56 and uses stanags seems overcomplicated compared to getting an ar.
1500$ is an extremely expensive rifle if you're not an enthusiast. You can get a PSA ar15 for 5-700$ and it'll go bang every time and leave you money for glass, upgrades, mags, and other stuff.
Plus, ars have vastly more aftermarket parts and if your gun breaks it'll be a lot easier to get ar replacement parts than ak replacement parts.
I'll always advocate for a basic ar15 for a first gun
- ammo compatibility, 5.56 is plentiful
- you can share mags with other ars
- it's easy to get parts
- tons of aftermarket crap if you want that
Sbr "pistols" are a gimmick for dorks who want to be operators and think they're smarter than the atf. The reduced weight can be nice but you're making your life much more difficult with all the regulatory bs in exchange for like 6" or something of shorter barrel. A carbine length rifle is good enough for anything you'd ever need.
Regardless, guns are worse than useless without regular practice. You gotta commit to doing dry fire practice, working on clearing jams, range time, and probably learning a little bit about squad level rifleman tactics. If you don't put in the practice and education you won't be able to fight at all.
Also - before you even buy a gun - take a stop the bleed course, get some na rescue tourniquettes and learn how to use them, get a basic "someone has been shot" first aid kit together. Statistically you're much more likely to kill or injure yourself than you are to ever use your gun in any defensive situation. Having a good first aid kit, practicing with it, and knowing how to use it is at least as important as a gun right now.
You can get a drop-in .22lr bolt for ar pattern rifle so you can practice with much less expensive .22lr instead of 5.56. Idk how much they cost these days but they used to be under 200$
