When Reassembling the Bolt of the M-16 A2 Why Are the Gas Rings Staggered?

When you reassemble your bolt on your M-16 a2 and wonder why the gas rings are staggered, there is a good reason. If these are line up then too much gas is allowed to escape and then the bolt will not go back in the locked position. So, staggering your gaps are very important.
