Tunable muzzle brakes can direct muzzle blast, or just blow up watermelons (VIDEO)

Demolition Ranch field tests a set of tunable muzzle brakes in 5.56 and .308 to experiment with directing muzzle blast for fun and profit.

The brakes, marketed by California-based Ares Armor are their MKII Effin-A Compensator series that use 8 columns and 3 rows of exit ports that can be either opened or closed through the very simple use of set screws to adjust your blast to port in whatever direction you want, for whatever reason you want.

And, in typical Demo Ranch fashion, can make one heck of a watermelon detonator device.

So gross.
