I have many, in both 7.62 and 5.45. I actually like them a lot. A 5.45 in an AK-105 configuration is probably superior to the M4, especially in a SHTF situation. It's a fine go-to rifle.
except for the lack of readily available ammo.
with a 5.56, in a SHTF situation, you can easily take clips off a dead cop or nat guardsman.
with a 5.45, what you got is what you got.
I'd rather have rifles/pistols in easily acquired calibers. 5.56, 7.62 NATO/.308, 7.62x39, 9mm, .22, 12ga, hell, in some parts of the US even a 30-.06 ect...
hence the reason I never picked up an FN Five-Seven or a .243 or a 6.5.... ideally, you'd have something in every caliber. lol.
I love the AK, but I'm a bigger fan of the FN-FAL (preferably in a tactical folder with a 14in barrel

).... "ak for the masses, FAL for the classes." lol
