AR15 or AK47? Which is better?
This is a comparison video on the penetration power between the AK47 7.62 x 39 mm cartridges and the AR15’s 5.56 x 45 mm cartridges. In the test we only had one kind of AK47 round but XM193, XM855, and PPU .223 rounds were tested in the AR15. The firearms used were a CIA AKM and a Sig Sauer 516. The test was for one round to penetrate the full block.
Watch to see what happens.
