JK Armament Booster/3 Lug Adapter Features The JK Armament Booster/3 Lug Adapter is machined from 7075 billet aluminum with a Type III hardcoat anodized finish in black delivering a lightweight 0.50 oz thread adapter at 1.55 inches diameter for use with the JK 155 suppressor and compatible 1.375x24 TPI HUB mount threaded suppressors. The 1.180x24 TPI external thread interfaces with the suppressor body while the internal thread accepts compatible pistol boosters and 3-lug mounts from a range of manufacturers. Type III hardcoat anodize provides surface hardness and corrosion resistance appropriate for a suppressor-mounted adapter component in sustained use. The HUB mount compatibility extends the Booster/3 Lug Adapter s utility beyond the JK 155 suppressor to any industry standard 1.375x24 TPI threaded suppressor broadening its usefulness across multiple suppressor platforms. The adapter is available in three internal thread sizes to accommodate pistol boosters and 3-lug mounts from different manufacturers. Precision machining from 7075 billet aluminum ensures consistent dimensional tolerances for reliable fitment across compatible suppressor and booster configurations.
