(R)ecoil (R)eduction (D)evice – (360) Degree Ports (HD) Heavy Duty – (18) M18-1.5 Threads (T)TaperMount – (X37)1.375-24 External Threads
The RRD-360HD is designed specifically with short barrels and high pressures in mind! Due to excess pressures and gasses associated with rifle calibers in short-barreled firearms, a barrel length restriction was put in place for many of our popular devices. To remedy this, we’ve taken our 360 design and reinforced the device by adding additional material where it’s needed and removing material in some areas to cut down on size, and weight. You get the same amazing performance out of our 360 devices, now with a Heavier Duty design for short-barreled firearms!
The 360HD-18T-X37 is designed specifically for tapered barrels such as those found on the Sig Sauer MPX, MCX, and M400 as well as Faxxon barrels. This X37 device will allow you to attach 1.375-24 HUB compatible suppressors and accessories to your firearm. In addition to a HUB compatible suppressor, the 360-18T is also compatible with any of our X37 Blast Diversion Shields (BDS).
This device is designed for tapered barrels, not standard shoulder mount application!
