Description
The Sig Sauer NG762 is a sound suppressor, rated for .308 / 7.62 NATO, 7.49'' long, built in Inconel.
This is an NFA item, so the process differs from an ordinary firearm purchase. It transfers on a Form 4473 with a NICS background check, the same as any other firearm. State law may still restrict or prohibit it where you live. Since 9 October 2026 the ATF no longer enforces NFA registration or approval for suppressors and short-barreled firearms, and the transfer tax has been $0 since 1 January 2026. Your own state law did not change, so check it before you order. You cannot take possession until ATF approves the transfer – the item stays with us until then. It can be registered to you as an individual or to a trust.
It is rated for .308 / 7.62 NATO. A suppressor may be used on a cartridge at or below its rating and bore diameter, but never above it – firing a larger bullet than the bore allows is how a baffle strike happens, and that destroys the suppressor.
Inconel is a nickel-chromium superalloy used where the blast baffle takes the most heat and erosion. It is heavier than titanium and is what allows a tube to be rated for sustained fire.
Suppressors reduce the sound of a shot; they do not silence it. How much quieter any given setup is depends on the host firearm, the barrel length and the ammunition – subsonic ammunition is much quieter than supersonic through the same can, because the crack of a bullet passing the sound barrier happens downrange and cannot be suppressed at the muzzle.
