In our search for a short lite weight muzzle brake, we ended up designing our own. They weigh less than one ounce and only add 1″ in length. They are surprisingly effective. So don’t weigh down your lite weight, expensive rifle build with a long heavy brake. Give ours a try. They are made of 7075 aluminum, hard anodized, threaded 5/8-24, and come in 6.5mm, and 308. They can easily be opened up for larger calibers.
