This item is a plastic toy. The M433 round is a workhorse of sending some love down range. Whether it be with the M203 or the MK19 one cannot deny that it runs off the same slogan as the Military. “Hurry up and wait” Slower to time on target, but once it reaches its destination, the boom is worth the wait, especially when lobbing a volley from a MK19 from a gun truck. This is a perfect gift for any veteran who studied in the arts of 11 Bravo or for any military lover who just likes cool stuff to showcase. Great for storing random stuff and provides a pretty solid seal. These are great for having in a man cave or the bathroom medicine cabinet. Who doesn’t love taking vitamins from a grenade round.
