Dead Air LT311 HUB Direct Thread Mount M18x1 4140 HT Alloy Steel Black Nitride

The Dead Air LT311 is a HUB-compatible direct thread mount that lets you screw a suppressor straight onto a firearm barrel threaded in M18x1 with no flash hider or muzzle device in between. Built from heat-treated 4140 alloy steel and finished in black nitride, this low-profile adapter threads into the barrel and presents a standard 1.375x24 HUB interface on the suppressor side, making it a drop-in mounting option for the Dead Air Nomad-30, Primal, and any other HUB-compatible suppressor.

At only 0.765" long, the LT311 adds minimal length to your muzzle while delivering the same rugged, repeatable attachment the HUB system is known for. The black nitride finish resists corrosion and wear, and the 4140 HT steel is built to handle the heat and pressure of repeated suppressed fire.

Whether you are running a Primal on a hunting rifle or a Nomad-30 on a hard-use carbine with an M18x1 threaded barrel, the LT311 gives you a clean, direct-thread mounting option that keeps your suppressed setup tight, aligned, and quiet.
