Our mission is to develop cutting edge, innovative gear, built for hard use: on duty, in defense, or in competition

Sintercore is a U.S. Marine Corps combat veteran owned company based in Grand Rapids, Michigan, and formed in 2013. Our design philosophy is to combine a sleek, distinctive aesthetic quality with a simple, reliable concept. Our tagline - Layered Defense - refers to the fact that we regularly design shooting gear that is produced using advanced, laser-based additive manufacturing (3D printing) equipment.

Our original product was the 3DX muzzle brake: the very first commercially-available, additively-manufactured  metal firearm product. Made of pure Inconel 625 and laser sintered layer by layer, the 3DX drew significant attention when it survived more than 8,000 rounds of semi- and fully-automatic firing during a test by Phil White of  The Firearm Blog  and made the  front cover of issue 09 of RECOIL Magazine  and was  featured in their Sig P556 review. It has since been discontinued, but we are developing successor muzzle devices at this time.

We were honored to have been chosen to provide muzzle brakes for demonstrations by ARES Defense™  of their AMG-1 and AMG-2 belt fed machine guns for US Special Operations Command (USSOCOM) Science & Technology Directorate personnel at MacDill Air Force Base in August, 2014. The live-fire demonstration, partially shown in this  authorized video clip , was intended to showcase cutting-edge technologies for potential use with the  TALOS robotic exoskeleton

Since then, we have partnered on additive manufacturing projects with industry professional Eric Mutchler, inventor of the  world's first 3D printed metal handgun, and also released our flagship product, the  Tripwire ambidextrous charging handle  and its derivative for base charging handles, the Tripwire xRS -Ambidextrous Retrofit System. Our latest products, as of April 2017, are  Deadfall   :   the first everyday carry optimized slide charging wings, and R3  :  a universal scope throw lever that blends in while sticking out.

Everything is made in the USA. All of our products are guaranteed by a lifetime, unconditional, no-questions-asked warranty. Please call  616-843-0351  or email  sales@sintercore.com  with any questions or comments. Our mailing address is 15 Ionia Ave SW, Grand Rapids, MI 49503.
