Start with some .223/5.56. AR-15's are love, AR-15's are life.
We have a .22 and 9mm pistol at home so I will probably use the .22. The owner of the range lets us use his weapons too and he has a dank .22 revolver and lever action rifle.
I really want an m1 garand at some point but theyre expensive as loving stuff. Like y tho, didnt the americans mass produce them back in ww2
Also automatic weapons are illegal in this stuff country do no ar-15 :(
