These integral single port brake direct thread mounts are designed specifically for pinning & welding suppressors to short barrels for “one stamp” rifles.
Made from 17-4 H900 stainless steel, they offer additional protection over a simple direct thread mount for your blast baffle on a permanently mounted suppressor, and are “featureless” on the back end for a clean, OEM look when installed. They have a .4″ long “tail” to provide plenty of real estate for pinning, which is of typical AR barrel diameter for the most seamless look possible in the majority of applications. These will extend .5″ behind the rear face of the suppressor, making a 6″ can long enough for “one stamp” rifles with 10.3″ or 10.5″ barrels.
One lightening hole has been omitted to provide a place for a pin through the side of the suppressor into the mount for those who are unable to or do not wish to perform a full circumference fusion weld.
To properly install these, you will need a collet fixture, jaw chuck fixture or some other means of securely holding a round part with no tool features.
Full circumference fusion welding should only be done with a TIG machine (or laser) by a competent operator. We recommend 3 tack welds 120° apart, then rotating the can at approximately 2.4 RPM (11.3 inches/min) and around 45 amps power setting for TIG, but every machine behaves a little differently, so know your set up. Too much heat input from high amperage or insufficient surface speed may cause distortion and/or “pulling” that results in axial misalignment.
We do offer pinning & welding services, refinishing services, and can weld the mount into most steel or stainless steel bodied suppressors. Please contact us if you would like to know more about this service. Titanium suppressors will need to have the mounts pinned & welded into them until we’re able to get titanium versions made.
