I've seen a few numbers, but they are all over the map on different sizes. Is there a standard opening size for certain barrel lengths, or is it common for a large difference in gas port opening sizes on the AK? I'm showing this so far: 223 Rem in AR-15- gas port .065"-.067" 300 Blk Out gas port- 14.5" barrel= .081" opening, 9" barrel .125" opening AK-47 opening ??? Any info? Thanks!
