Description
The Inland Manufacturing Inland MFG is a sound suppressor, rated for 9mm, 8.50" long, built in aluminium.
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.
The suppressor threads 1/2"x28. The host barrel has to be cut to exactly that thread – 1/2×28 is the usual thread on .22 and 5.56 barrels, and a mismatch will either not start or will cross-thread. If your barrel is a different pitch you need an adapter or a different mount, not force.
It is rated for 9mm. 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.
Aluminium is the lightest of the common tube materials and the least heat tolerant, so it appears on rimfire and low-pressure pistol suppressors rather than centrefire rifle cans.
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.
