Fwiw, am a really thrifty/frugal broke near hermit
Depression's improved to the point I'm not concerned with it being a risk to myself and am currently nogunz except for varmint air guns
Considering dropping like two grand on a nice rifle 
and equipment and training with it alongside my gym routine
Debating getting either a KUSA KR-101X or a Keltec RFB and an optic and chest rig/plates and pouches, spare mags, etc for either
The KR-101X is a 5.56 AKM/74 clone that takes AR mags and looks pretty good from what I've seen, the RFB is a .308 bullpup DMR (I'm kinda a tankie and a big Halo dork, so both have their appeals)
Live in a state with a 10 round mag restriction, so that's leaning me towards the RFB.
Thoughts?
Dunno if there's a loophole for larger mags or a SBR "pistol" 
that might be a better option
Am I being a dumbass?
Should I get a pistol or a .22LR plinker first? Should I not drop a used car price on a rifle I might never have to actually use aside from playing at the range and running drills as a hobby?
@Tervell@hexbear.net pls lend me your wisdom and recs
A .22LR plinker is always a great choice. The ammunition is the cheapest and you can shoot it all day without hurting or going broke. It’s a great way to improve your overall technique and accuracy. If you get a rifle and a pistol, you can develop both skills with the same ammo, probably for less than a good 9mm pistol. In the mean time, if you go to some ranges with a friend you can rent something to try it out to see what you’re comfortable with.
I haven’t bought a gun in several years, so I’m not really sure what prices are like rn.
Worth going to gun shops and pawn shops to see if they have a cheap ruger 10/22. Idk what prices are like now but a few years ago you could sometimes find them under 200, sometimes with upgrades already insyalled.
Ruger 10/22 is the best way to start. Teaches you all the basics, cheap, and malfunctions more than any AR I've fired from the get-go, so you'll at least get experience clearing jams. Good range of mag sizes
Probably cheaper from a pawn shop, but they are very cheap new (for a gun).
I cannot possibly repeat this louder! Habits are more important than hardware, so make them affordable. Like a bicycle you can move from gun platform to platform once you hammer out the basics.
