Description

The Blast Diversion Shield (BDS) was designed as an optional accessory that can be quickly attached to our X-Series muzzle devices and direct the blast, sound, and concussion away from the shooter’s ears.

The BDS threads directly onto the external threads of the corresponding X37 muzzle device and can be easily removed or replacement by a suppressor.

In addition to our X-Series devices, the BDS can also be used with a wide range of suppressor adapters/mounts to include KeyMount, ASR, AAC, and 3 Lug mounts.

The BDS does NOT include any mounts, please select from pull down menu!

BDS20 Blem

Zack on Sep 21st 2024

Works excellent with the JMAC 3 port 360, on (5.56) and the single port Dead Air KeyMo (9MM 16"PCC) breaks. Definitely more efficient at pushing the sound away than linear breaks/blastcans that do not incorporate ported breaks. No noticeable deference in increased recoil with the BDS attached. Got a BLEM, had no blem I could find.

Blast shield

Very clean fit and finish

Fits like a glove

Christopher on Sep 1st 2023

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.

SHIELDS BLAST AS INTENDED

Corey on Apr 21st 2023

I bought this to keep on my HUB adapter when I'm not using a suppressor. Works as described. I like the texture at the end of the device as it protrudes from my handguard giving a nice grip for removal/application.

Awesome blast device

Jesse Smith on Apr 4th 2023

I absolutely love Jmac products and this one was no exception. I would give it 6 stars if I could. Do yourself a favor a pimp your ak out with their stuff. You can’t go wrong.

Love the way it looks

Jonathan on Dec 26th 2022

I bought this for my Riley Defense rak 47 and it fit nicely and snug without any tools. The crush washer didn't fit on the bag it said 5.56 but it wasn't needed anyways. I definitely recommend if you shoot in the prone position or live in dusty areas.

This blast shield looks absolutely perfect under my handguard! Just the last 1/2" sticks out when mounted onto a keymo adapter. Works with keymo flash hiders and brakes too.

Sweet addition to a spare Keymo mount. Threads smooth and clean lines. Already ordered a second one.

BDS37

UT74 on Dec 7th 2021

Wanting to add more of the the AKS-74U look to my KP9 SBR, I decided acquire the BDS37. To say the least it fit the bill perfectly and performed as designed. Sound and expanding gases are directed forward while sharing the aesthetic appeal of the 4 piece Bulgarian booster. Very well made and ZERO slop. I highly recommend to tighten this device down with a tool. Hand tight might have a tendency to come loose. Thumbs up!!!

BDS-37 with KeyMo AdapteR

Boris Del Cid on Nov 22nd 2021

I received the BDS-37 with the KeyMo adapter. The quality speaks for itself…SOLID! The installation was ridiculously easy….I thought maybe I did it wrong, cause it could not have been any easier. The design is nice and It looks fantastic.I have not gone to the range to shoot with it, but I am certain this product will be just as good as any other JMac products I own. The price is definitely up there…no doubt that it’s not cheap, but thankfully I can afford it. Price not withstanding, I give it a 5 stars

SEAN on Aug 26th 2021

This thing is the SHIT!!!! Versatile and well machined. Would be cool if it came with a wrench but no complaints here. Rigorous testing is forthcoming but I am sure it will hold up well.

Great product

Daniel Salzman on Jul 21st 2021

This linear compensator or blast mitigation device works great it's a nice alternative that works great with my dead air keymo adapter.

BDS-37 w/ KeyMo

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.

BDS-37

Jorge Sandoval on Mar 24th 2021

Works perfectly....fit 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

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.
