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.
The BDS-37 Blast Diversion Shield was co-developed with our RRD-2C X series of muzzle brakes with external threads. This blast shield threads over any 1.375-24 threads and diverts the blast forward, reducing side blast/concussion.
Fantastic build quality. Fits on all my tri-lugs perfectly. The fit and finish are absolutely superb. I haven't taken it to the range yet, but from word of mouth alone I am quite confident in the quality of this product. JMAC will certainly be my future go-to on muzzle devices.
