BDS-37 - HUB Blast Diversion Shield

Excellent quality product with great packaging and quick shipping. Thank you.

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.

Very clean fit and finish

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.

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.

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.

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.

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!!!

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

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.

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

Another great product!! I love all the jmac products I have tried

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 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)

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.
