For decades, a debate has raged in the firearms community, a debate about AR-15 versus the AK-47. 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.

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.
