(B)last(D)iversion(S)hield(37) 1.375-24 threads


Our BDS Blast Diversion Shield was co-developed with our RRD-2C X series of muzzle brakes with external threads. This blast shield threads over our 2C X and diverts the blast forward, reducing side blast/concussion.

In addition to threading over the RRD-2C X, the BDS can also be used with a wide range of suppressor adapters/mounts, see below.

Blast shield does NOT include any mounts, please select from pull down menu!

 If you plan on using with the following muzzle devices you will need the adapters

BDS-37 w/ KeyMo

Written by Troy on Apr 7th 2021

I installed the BDS-37 onto my KeyMo mount and it fits perfectly. It looks great on my guns when I'm not running a suppressor. I have not had a chance to shoot with it yet, but I'm sure it will work very well based on the design alone. And the quality seems to be the expected typical high-quality of JMac products.

Works the asr Bravo adapter and sound was mitigated forward without producing more recoil...will Def recommend (used with both Lantac Asr Dragon Muzzle Brake and Single Port Asr 9mm muzzle brake)

Atlas 7.62X39 Build

Written by Michael Vater on Oct 13th 2020

I couldn’t possibly be more satisfied with my purchase. The 10.5” barrel on my pistol can get loud at times and the Shield seriously improves the long days on the range. The corresponding Muzzle Break was an absolute must have. The Guards tight threading is smooth as silk when I remove it and the muzzle device makes an uncontrollable firearm a perfect target pistol.
