WTF? Just saw one of these for sale online for 435 bucks!!! I figured it was a joke so I googled it and thats about the average price. Seriously? for a muzzle break?!?! Whats does it do so special? reduce the recoil and muzzle rise to that of a bb gun? make every shot go through one jagged hole at 500 yards?!

Seriously though, anybody know anything about these?!
