Not a chance it's for peeking around corners. It is a bad idea if you think about it. You never stick your weapon into an unchecked space, which you'd have to do to get the mirror far enough to give you a view around a corner, given where it's mounted in the pics.
BUT!!! If you get that picatinny muzzle break, THEN mount this to it... it might work. That'll scream 'bad ass.'![]()
