HD Wolfe,
Seriously. Try fitting on of these on the barrel. It might take a bit to slip on on, but it works! You can by a deresonator for $12-20 depending on where you look.
Here are the Masen Muzzle breaks. They make a difference as well. Put the Simms on
before or you will be stretching that baby to get itover the muzzle break I know, I had to do it!
I got mine from Midway.
God Bless,
Porter.
