While there seems to be no end in sight, the AK-47s little sister, AK-74, designed by Russians in the late 70s to counter AR 5.56x45mm NATO cartridge, actually is the one that performs very similar, ballistic-wise, to an AR-15, and thus is much closer to run a comparison.

The AK-47 shoots the World War II-era 7.62x39mm that the Russians designed in 1943. The AK-74 shoots the 5.45x39mm cartridge that performs very similar to the 5.56x45mm NATO cartridge. So now, let’s take a look at the AR-15 versus AK-74 from a practical point of view.

This is for an AR-15 lover. What if your AR-15 could shoot in semi-automatic with sub-MOA accuracy to 1,000 yards and beyond? In 2018, you can! But how? There are two calibers to consider.

6065 or 7075 - which aircraft-grade forged aluminum alloy is best for AR-15 lowers? Selecting a grade is one's task on finding a balance between performance and cost. 

 

A good place to start is by understanding similarities and differences between 6065 and 7075 aluminum alloy.
