Designed to be HUB compatible, using the HK tri-lug interface, the Heavy Duty 3-Lug Adapter can replace any industry standard (HUB) 1-3/8"-24 mount. Machined from 17-4 stainless steel, the HD 3-Lug Adapter is durable and capable of heavy use, including full-auto. The HD 3-Lug adapter can be swapped onto your R9 or Nitro N20 Sound Suppressors, and can be used on some rifle calibers. This is the perfect upgrade if you are looking for a quick-attach mount with better longevity-especially on full auto platforms.
