(GunReports.com) — Sintercore LLC of Grand Rapids, Michigan, is billing its Auxetik as the first 3D printed muzzle brake available on the commercial market.
Sintercore’s owner is Neal Brace, an inventor, firearms instructor, and former active duty U.S. Marine infantryman. He said, “We aim to make 3D printing understandable and accessible to everyone who’s interested.”
Auxetik, pronounced “Awg-ZETIK”, was designed and crafted specifically for this new process, Brace said. Laser sintering allows for both complex internal features and unconventional external forms.
He’s billing it as an innovative solution for SBR’s and pistols, that is, enjoy the benefits of a short firearm with less of the annoying concussion.
Features include 3D printed linear gas vents, which allow an amount of gas to meter out of the first expansion chamber and flow forward into the second expansion chamber for increased concussion control. These vents could not be easily made in a traditional machined, cast, or EDM’d part, Brace said.
Dual internal expansion chambers funnel gas that flows into the second expansion chamber against a forward-biased wall and is expelled both sideways and to the front, reducing recoil, eliminating muzzle rise, and further controlling concussion.
