Description
The QD Blast Shield was designed to offer significant concussion reduction for the end user and other team members operating in the immediate vicinity. Often team members in CQB environments experience concussion from muzzle blast that is not only deafeningly loud, but also can cause prolonged headaches that can last for days afterwards.
Especially effective on short barrels, the unique design of the QD Blast Shield directs concussive force forward allowing an end user to rapidly reconfigure muzzle device function. Ultra strong 17-4PH stainless steel and Tig welded construction provides a robust material and build method to withstand intense use and full auto fire without fear of failure. The body is fluted in the same way as our QD suppressors, increasing strength to weight ratio for added geometrical strength, while increasing surface area for faster cooling.
Melonite QPQ surface treatment provides an extremely hard, durable, and attractive finish.
The QD mechanism is fast, positive, and free of wear prone geometry commonly found in ratcheting devices. The QD Blast Shield also comes with a shim set and overtravel stop to refit your A2 compensator for optimal use.
The Griffin QD Blast Shield is compatible with our line of Gate-LOK™ mounts in 7.62 and 5.56mm, including the Gate-LOK™ Flash Comp (5.56mm), Gate-LOK™ Hammer Comp (5.56mm), Gate-LOK™ Stealth Flash Hider (5.56), and Gate-LOK™ Flash Comp .30cal (7.62mm). Discontinued products the QD Blast Shield is compatible with: M4SD Muzzle Brake, Linear Comp, Compensating Flash Hider, & Tactical Compensator. Not compatible with 30SD Flash Suppressor and 30SD Muzzle Brake
It is also compatible with A2 Compensators that fall within the USGI A2 spec blueprinted dimensions. Silencer interface was designed to fit the USGI A2 government contract compliant muzzle devices. We cannot guarantee fitment with an A2 style compensator due to the broad tolerance range of both import and domestic devices from various brands. For guaranteed fitment, we recommend the purchase of a Griffin mount.
Although many companies manufacture A2 style compensators not all of them are dimensioned properly. Not Compatible with BCM, BCE or PWS muzzle devices.
Griffin Armament has continued to pursue product development that will enhance hearing safety in tactical and shooting sport situations. The QD Blast Shield is a great product for those that would like to reduce the concussion of their muzzle devices.
Compatible up with projectiles up to 9mm.

The instructions for the Hammer Compensator states that you put the tab at 6:00, however it doesn’t fit right. The side vents will be blocked and the retainer does not go in all the way. If you look at the pictures it shows the retainer on the left side of the barrel which means that the tab is at 9. There it goes in perfectly

Does a great job of pushing the concussion forward of the shooter, an absolute must have if working in CQB environments. Love the look of the GEN 2 and it seems to mitigate flash better than the GEN 1. Keep up the great work guys!!!!

The material and finish quality is superb. I am very pleased with the products performance. While the blast shield does not suppress sound it is very effective at directing flash and sound down range it gives the shooter the impression it does.
Great product.

Its not very often that I’m so impressed by a new product, but the new Gen II blast shield works better then I was expecting. Concussion is reduced to almost nothing, and noise reduction is reduced significantly as a surprise bonus. Great product that I recommend highly.

I don’0It have experience with linear comps, but because I own a 30SD, I decided to give this a try. Just for the comfort, it provided at the indoor range was worth it for me. Nice to just be able to leave in your range bag. Yes. It’0Is worth it.

Description states that it is NOT compatible with BattleComp (BC). Already had a BC 1.0 in 5.56 bought a year ago and tried my new Blast Shield 2.0 on a whim. Was pleasantly suppressed to find it fit easily and just as snuggly as in my Griffin brake. Well built. Haven’0It fired yet so can’0It comment on effectiveness.

I have griffin taper mounts on all of my rifles except for two 16″ rifles. One has a VG6 Epsilon and other has A2. The blast shield for the taper mount works great on the other mounts, so I figured i’d give this a try on these rifles.
Fits VG6, that’s a real plus. Does not add a lot of length, does what it’s supposed to do and also has a very nice aesthetic appeal. Looks bad ass actually. At first, i thought it was expensive and negates why i got a comp/brake but after getting it, i’m happy with the purchase. It’s legit and i’d easily buy it again.
I really like griffin mounts but i already had the VG6 and kinda got married to it on this particular rifle and don’t want to change it. When you need to consider those your shooting around, I recommend this blast shield. If you have taper mounts, the other one is awesome.

I saw some online complaints of the Griffin cans not fitting on all A2s. I bought it anyway. Didn’t fit on the “A2” from Palmetto. Grooves that “A2” were very shallow and obviously out of spec. Ordered the milspec A2 from Wilson Combat for less than $8 and it was a perfect and snug fit. Love it. Works perfect and looks absolutely amazing. Buy it. I’m buying another.
Mitch Price –
Absolutely the best!! in all respects

The Blast Shield Gen 2 Looks and Performs fantastic.
In the description they say it’s not compatible with BCM Muzzle Devices but I will tell you it fits/ works excellent in my BCM MOD 0 Brake. These Blast Shields beat the hell out of the finish on the muzzle devices though but that’s with other brands as well.

To it to the range and it works great! Only a 4 star because only shot about 50 rounds and when you take the blast shield off the finish on the flash suppressor already had carbon residue on it.

I purchased the Griffin armament gen 2 blast shield and it locks up to my b.c.m. mod 0 comp. Very nicely. I have no muzzle flash at all with the blast shield. Thank you Griffin armament.

Turns out a lot of manufacturers are making slightly out of spec A2 flash hiders. It’s not very surprising, these things retail for around 7 bucks. I have a few on hand to test and found that both my BCM and PSA A2’s were just oversized enough to prevent the blast shield from locking on. My CMMG A2 works fine. YMMV, we’re talking about variances measured in thousandths of inches here.
I also have a BCM Mod0 comp that is advertised as being compatible with A2 accessories and it does indeed work.

Well built and gets the job done

Shipped fast, packaged good, fits perfectly on my VG6 muzzle brake. Feels really solid, welds look great and it should last a long time.. Didn’t come with instructions, but it’s really self explanatory. Plus they gave me stickers, thank you Griffin Armament!

Solid feel with attention to fit and finish. I took a chance with it on my 14.5 BCM w/ Mod 1 compensator. I needed something for use at my local private range, as the blast and concussion was making it hard to make friends with those to the immediate left and right of me. This blast can does as advertised and appears to be compatible with my muzzle device. There is slight forward/back jiggle, but only by a millimeter or two. No chance for the round to strike the blast shield. I greased the contact point to minimize any wear. It did a fantastic job of sending the blast and concussion straight down range. I am sure it would be an issue with any competitive product, but I noticed a ton of copper and carbon fouling on my muzzle device after firing roughly 60 rounds, but that’s what they make solvents for. Shooter and range neighbor approved!

Great product!!! I own the Gen 1 when it came out. I love the design of both the Gen 1 & Gen 2. Great accessory for my 10.5″ uppers. Only a couple of range sessions so far and it’s been good.
Christopher Griffin –
Beautiful fit Well built
Jon –
Works as stated. Really happy with it.
Kevin B –
Functions just as good as it looks…which is great!

Great product and it really works
fallhuntsman –
I bought this on sale – it was a great price! Anyway, Id been looking at it for a bit. I have a 10.5″ that if fits nicely on. The quick disconnect it amazing. Good design. Hides most Flash, and sends noise and Gas further out front. It does weigh it down a bit, but it’s worth it to me. A good purchase!
Paul –
Well made and easy to install. It’s just what I’ve been looking for because you don’t have to buy a seperate muzzle device hundreds of dollars. Works and does what its suppose to. The only thing I can’t really comment on yet is long term durability because I just started using it.
Gavin Alderman –
Works as advertised. Completely eliminated the flash on my rifle as well.
JG –
This thing looks and feels fantastic on my DD M4A1, I can’t wait to get it out to the range and try it out.
Griffin Armament’s products are truly the best value for money you can get and they have my business for the future!

I purchased this for my Daniel Defense DDM4V9. The blast shield initially fit on the A2 style muzzle device perfectly, but became stuck after a 150 round range session. Removing the device was nearly impossible. I was eventually able to remove it, but not after tearing most of the nitrite finish off of the flash hider, which I had to to have replaced. My experience may be a fluke, but I would recommend going with one of Griffin’s proprietary muzzle devices and not risk your flash hider with this product.

Love it will be buying again
