JK Armament 155 Booster/3 Lug Adapter

JK Armament 155 Booster/3 Lug Adapter Features The JK Armament 155 Booster/3 Lug Adapter is machined from 7075 billet aluminum for exceptional strength-to-weight performance coming in at just 0.50 oz. while providing the dimensional precision required for a rattle-free concentric booster or 3-lug to HUB adapter interface. Type III hardcoat anodizing provides surface hardness and corrosion resistance through repeated installation and removal cycles and the thermal demands of sustained suppressor use. The 1.203x28 TPI internal thread pattern adapts compatible pistol boosters and 3-lug mounts directly to the JK Armament 155 suppressor s 1-3/8x24 TPI HUB threads. The 1.55 diameter keeps the adapter consistent with the JK Armament 155 suppressor s profile for a clean low-profile fit without snagging or adding unnecessary bulk at the mount interface. The black hardcoat finish provides a uniform low-visibility appearance consistent with standard suppressor equipment. For JK Armament 155 users running pistol or 3-lug host configurations this adapter provides a precise purpose-built solution for bridging booster and 3-lug hardware to the HUB mount standard.
