I’d take an AK over an AR. The AR is just a .22
Before the nice folks at ArmaLite developed the AR15, they invented the AR10. It ain't a .22, and ArmaLite would still be happy to sell you one!
;^)
You might want to rethink your position. Neither the AK or AR are caliber specific weapons. Though the typical round for the AR is 5.56x45 they also make ARs in calibers from the 22 LR to 50 Beowulf. They also have made AR shotguns. Aks are typically 7.62x39 or 5.45x39 but I have also seen them set up for different calibers.
The AK can typically take more abuse and dirt, but the AR is much easier to repair. The tools to repair the AK are not that common and require some knowledge, but you can completely disassemble an AR down the last spring with less than $100 worth of tools.
Like the article stated, the AK was designed to give weapons to peasants with little training and less desire to keep their weapons clean. There are many good things and bad things to say about each type of weapon (because all designs are compromises). Most of the people I know that own one also own the other and like both.
Cute ... What calibe do you suppose the AK74 uses?
