In the debate between an AR-15 vs an Ak, consider this..
for under/around $500. you can choose from a variety of American -made AR-15 rifles,
that come with a warranty. Buy a 5.56/223 rifle & you can
add, a upper assembly in a variety of calibers: .300 Blackout, 7.62 X39, 450 Bushmaster, etc .
this flexibility, to have 1 lower assembly, mated to a variety of different caliber uppers, makes the AR format superior to the AK platform, IMO
That the AR format is easily modified (drop in triggers, different stocks, handgrips, etc) and the wide assortment of accessories available further supports my opinion.
I post this understanding that these facts have no weight to a AK fans..
