Description
Quick attach mounts used to mean adding a chunk of stainless steel to the front of your rifle. JK Armament went a different direction with the Pro Quick Attach Taper Mount, machining it from Grade 5 Ti-6Al-4V titanium so you get the strength for hard use while adding only about 1.3 ounces to your setup. When it launched, it was the first HUB-compatible titanium mount available, and it remains one of the lightest ways to put true quick attach capability on a HUB can. An Armor Black C-192 Cerakote finish keeps corrosion at bay and matches just about any suppressor tube out there.
How the Pro QA Taper Mount Works
There are no levers, ratchets, or locking collars to fuss with. Coarse threads spin the suppressor on and off in a couple of seconds, and a precision-machined taper surface wedges everything into solid, repeatable alignment with a full gas seal. That taper interface means no wear parts, no carbon lock headaches, and a lockup that stays put through rapid strings of fire. Built-in 1.5 inch wrench flats make removal easy when it is time to swap suppressors between rifles or break things down for cleaning.
Compatibility Across the HUB World
The rear threads are the industry standard HUB 1.375×24 TPI pattern, so this mount fits the entire JK 155 series along with dozens of suppressors from other makers, including popular cans from SilencerCo, Dead Air, YHM, Otter Creek Labs, and Energetic Armament. On the firearm side, it snugs down over JK's own War Eagle and Bald Eagle muzzle devices as well as SilencerCo ASR pattern brakes and flash hiders, which opens up a huge range of host guns. At just 0.600 inches long, it keeps your overall suppressor length nearly identical to a direct thread setup.
Why Go Titanium
If you are running one suppressor across multiple rifles, this is the mount that makes it painless. Set up each host with a compatible muzzle device, then move the can between them in seconds without dragging extra weight to the muzzle. Like everything JK Armament builds, it is made in the USA and backed by a lifetime guarantee.

Frequently Asked Questions
Which suppressors will the JK Pro Quick Attach Taper Mount fit?
It threads into any suppressor with the industry standard HUB 1.375×24 thread pattern, sometimes called Bravo or Omega spec. That covers the full JK 155 series plus dozens of popular cans like the SilencerCo Omega 300 and Hybrid 46, Dead Air Nomad, YHM Turbo T3 and Resonator R2, Otter Creek Labs models, and Energetic Armament suppressors.
What muzzle devices work with this taper mount?
It locks onto JK Armament's War Eagle and Bald Eagle muzzle devices as well as SilencerCo ASR pattern brakes and flash hiders. Some longer ASR-style devices like the Lantac Dragon and certain Battle Comp models may require a JK 155 tube extension for proper fit. That flexibility means you can set up several rifles with inexpensive muzzle devices and run one suppressor across all of them.
How is the Pro version different from the LT taper mount?
The Pro is machined from Grade 5 Ti-6Al-4V titanium and Cerakoted, while the LT is 7075 billet aluminum with a hardcoat anodized finish. Titanium handles heat and hard use far better than aluminum, so the Pro is the pick for centerfire rifles that see high round counts or rapid fire. The weight difference is minimal, with the Pro coming in around 1.3 ounces.
Does the JK taper mount have wear parts or need special tools?
No. It is a simple taper interface with coarse threads, so there are no springs, latches, or replaceable parts to wear out. The taper surface self-centers for repeatable alignment and a solid gas seal every time you attach the can. Built-in 1.5 inch wrench flats let you install or remove it with a standard wrench.
