BANISH Suppressors has announced the HD 762 INC, a dedicated 7.62 NATO/.308 Winchester suppressor made entirely from additively manufactured 718 Inconel. It is the second model in the company's Heavy Duty (HD) line after the HD 556 INC, and like its little brother, it is aimed squarely at gas guns: AR-10s, 6mm AR-15s, gas-operated precision rifles and SBRs.
The material choice tells you most of what you need to know about the intended use. Inconel 718 is a nickel-based superalloy that keeps its strength at temperatures where steel and titanium start to lose interest, which is why it keeps showing up in cans meant for heavy firing schedules. BANISH rates the HD 762 INC for full-auto fire with no barrel length restrictions, and approves it for cartridges from 5.56 NATO all the way up to .300 RUM. The company specifically lists high-pressure loads such as Federal's 6.5 Creedmoor +Peak and 7mm Backcountry as compatible, which is worth noting since 7mm Backcountry runs at chamber pressures well above conventional hunting cartridges.
The other half of the story is back pressure. Anyone who has put a conventional baffle stack on an AR-10 knows the routine: the rifle cycles harder, the bolt carrier group gets filthy, and the shooter receives a complimentary gas facial with every shot. BANISH addresses this with what it calls controlled-flow technology, using nine baffles and eight helical vents to steer expanding gas along a defined path instead of letting it push back through the action. According to BANISH, the result is low back pressure without giving up sound or flash suppression.
The HD 762 INC measures 6.7 inches long and 1.65 inches in diameter, and weighs 15.9 ounces without a mount. Inconel has never been anyone's first pick for a featherweight build, so keeping a full-auto-rated 7.62 can under a pound is a respectable result.
On the sound side, BANISH's internal testing gave an average of 135.7 dB at the shooter's ear with supersonic .308 Winchester from a 16-inch AR-10. Switch to subsonic .300 Blackout from a 16-inch AR, the average drops to 126.2 dB. Hollywood quiet it is not, and your earplugs get to keep their job, but at-ear numbers matter more than muzzle numbers on a gas gun, since that is where the ejection port makes itself heard.
Each suppressor ships with a 5/8x24 direct-thread mount, and the rear end uses industry-standard HUB threads, so it works with all the major quick-detach systems. There are also 1.9 inches of space before the first baffle, enough to fit a full-length muzzle brake or flash hider underneath. That is good news for anyone who wants to keep their brake, and even better news for whoever is shooting at the next bench.
The HD 762 INC is available in Black or Flat Dark Earth Cerakote, is made in the United States and is covered by BANISH's lifetime warranty, which includes damage from normal use as well as manufacturing defects. It is not user-serviceable, so owners will want to make use of the BANISH Service Program, which provides a full maintenance check within the first year of ownership. MSRP is $1,129, and the suppressor is available now through BANISH dealers.
Low-back-pressure 7.62 suppressors have become one of the busiest corners of the market, so BANISH is not walking into an empty room. On paper, the HD 762 INC makes a strong case with all-Inconel construction, a full-auto rating, no barrel length restrictions and a sub-one-pound weight at $1,129. The claims that matter most, back pressure and at-ear sound on a gas gun, are the ones independent testing will need to confirm, and I would very much like to see this one on a suppressed AR-10 next to a conventional can.
