The YHM-2050 HD (HEAVY DUTY) 3-Lug Adapter is a quick-attach mounting option designed to provide added strength and longevity to your 3-Lug equipped firearm. This fully enclosed assembly contains a mounting interface machined from 17-4 Stainless Steel-making it durable and capable of handling heavy use-including full auto. The HD 3-Lug Adapter is HUB compatible and uses the iconic, HK tri-lug interface. This makes for a versatile adapter, capable replacing any 1-3/8"-24 mount. 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.

Our BDS-37-EXT was co-developed with our RRD-360-24F-KM & RRD-369-26F-KM series of muzzle devices with external threads. This blast shield threads over 1.375-24 threads and diverts the blast forward, reducing side blast/concussion.
