Muzzle Brakes - what are they for? (Patreon)

Another long one, but going by the comments, even people who thought that they knew what muzzle brakes are for learned something.  I've been getting a steady trickle of e-mails from people who have experienced the force of the blast from a muzzle brake.

Another sponsored video, but as always, I declare that it is sponsored at the start, and I have left the sponsor's message bit as skippable.  If you have a PC keyboard, keep pressing right arrow to skip along.
