JK Armament 155 LT Quick-Attach Taper Mount, Black
The JK Armament 155 LT Quick-Attach Taper Mount equips a compatible 1.375x24 HUB suppressor with the rear interface needed for a matching taper-mounted muzzle device. The 7075 aluminum body keeps mounting weight to 1.1 ounces while providing the connection used to move between properly equipped firearms.
The mount belongs inside the suppressor. A compatible barrel-mounted muzzle device supplies the other half of the attachment system and is selected separately for the firearm's caliber and muzzle threads.
Choose the 155 LT Quick-Attach Taper Mount, Black at BattleHawk Armory.
Gas-Sealing Taper Connection
Coarse attachment threads bring the matching muzzle device and mount together, while the taper provides the seating and gas-sealing surface. That interface is designed to keep the suppressor connection consistent through repeated attachment. It is useful when multiple compatible firearms already carry the correct JK or supported ASR-pattern muzzle devices.
LT Construction
The LT mount uses 7075 aluminum with a Type III hard-anodized finish. External 1.5-inch wrench flats provide a defined tool interface. The material and compact mounting body help limit weight added at the rear of the suppressor.
HUB Fitment and Muzzle-Device Clearance
The suppressor-side thread is 1.375x24 HUB. A matching thread does not remove the need to confirm internal clearance, mounting depth, and the suppressor maker's approval. The front of the mount must also suit the exact muzzle device; a direct-thread barrel connection is not the same as the taper interface.

Frequently Asked Questions
Is the barrel-mounted muzzle device included?
No. Choose a compatible muzzle device separately, with the correct bore and barrel thread for the firearm.
Does HUB compatibility guarantee fit with every suppressor?
No. Internal clearance and the suppressor manufacturer's mounting requirements must also be satisfied.
Can it be used as a direct-thread barrel adapter?
No. The quick-attach taper mount engages a compatible muzzle device, rather than the bare barrel threads.
