eabco.com has an assortment of brakes and installs them. I find the looks of the one adapted from the old military tanks appealing, but that is me. The brake "re-directs" the gas/blast... Yes, you will need alot more hearing protection, AND you want to think about where the gas is going. If you are laying down, you disappear into a cloud of dust thrown up around you... And if you are on a range... those on either side are not going to be thrilled with you... but then how much will you shoot. luck...
