Tip of the day: Don't fire a waterlogged AR-15!

This video clip is from a marketing video made by H&K comparing the 10″ barreled HK 416 with the M4 when fired full of water, immediately after being submerged.

It is a pointless comparison. Obviously Stoner did not design the AR-15 platform to be fired waterlogged. If he had it would be piston driven. Still, it is interesting to see what happens.

    Glock 22 in .40 and Glock 31 in .357 will fire underwater reliably.

    I've done it myself.

    LWRC M6A2 and M6A3 will also rife completely underwater reliably.

    I've done both of these drills myself.

    Waterlogged M6 = Working weapon. You just have to manually cycle it.
