Abstract:
An improved muzzle brake, attached to the end of a rifle barrel reducing the recoil of the rifle includes an internally threaded attaching end, engaging outer threads of a rifle barrel, a flattened projectile end, with an overall increasing taper from the attaching end to the projectile end, a flat upper surface which does not impede the sight line of the rifle, a flat lower surface, and two lateral surfaces including a first lateral oval vent, a second lateral oval vent and a third lateral oval vent, the first lateral vent defining a first flat brake plate having a first central bore, the second lateral oval vent defining a second flat brake plate having a second central bore and the third lateral oval vent defining a third flat brake plate having a third central bore penetrating through the projectile end, wherein a bullet fired from the rifle travels through the attaching end, the first central bore, second central bore and third central bore, while the gasses generated by the fired projectile are deflected laterally by the first flat brake plate, second flat brake plate and third flat brake plate, forcing the rifle forward, reducing the recoil force of the fired rifle.

Sound cool? It is, especially in operation!

PS. Here are a couple pics of it so you can see the backwards angle:

I'd forgotten the brakes were directed backwards  . Never fired one myself but I did see an accurized .338 LM rifle in action going for 20 oz. water bottles at around 400 meters. It was really cool to see how high those things would fly when you hit 'em just right.
