Griffin Armament makes a suppressor for the AR15 family of rifles that makes use of the rifle’s factory flash suppressor for an economical mounting solution.
One of the challenges after buying a $600-$1000 rifle silencer, paying the $200 NFA tax and waiting from six months to a year for the approval is acquiring mounts for the host firearms.
Some silencers are direct thread, but for use on a rifle or collection of rifles, the QD mount is quicker. QD mounts from different manufacturers can cost anywhere from $50 to $250 each. We were looking for one that would use the AR15’s existing flash suppressor.
There is nothing wrong with the A2 flash suppressor. The USGI A2 flash suppressor was designed in 1985 as an improvement over the older style “birdcage” flash suppressor which was prone to kicking up dust when fired in the prone position. By sealing off the bottom port, the designers inadvertently created a flash suppressor that acts more like a compensator to improve accuracy.
Yet, to see the spare parts boxes at anyone who runs silencers on their AR15 rifles, you would think that the A2 flash suppressor is a junk part like the AR15 A2 pistol grip.
The folks at Silencershop.com referred us to the Griffin Armament M4SD-II suppressor. For those not familiar with Silencershop.com, they are the Amazon.com of the NFA world.

Staffed by a team of experts who know NFA laws, how silencers work, what they are made from, etc. Silencershop.com had the answers when we were looking for a can that could mount to a number of host rifles sporting the A2 flash suppressor.
The Griffin Armament M4SD-II suppressor is the end result of over a decade of computer design, field testing and actual combat use in Afghanistan. It is lightweight and very durable, plus it keeps the noise and back pressure ratcheted down to safe levels.
Decibel reduction is rated at 35 decibels according to Griffin Armament and Silencershop.com.
Construction of one of these silencers starts out on CNC Machinery and made from 316L stainless steel. It is fully TIG fusion welded for maximum thermal transfer and strength. The baffles are made from heat treated 718 inconel. The suppressor bores are wire EDM cut for maximum accuracy and fully blueprinted tolerances. This was our first hands on opportunity with a Griffin Armament silencer and we are eager to try out more if Silencershop.com has any left in stock.
The best part is the mounting system, touted as the fastest in the world.
Line the mount with the rear ring of the A2 style Flash suppressor and press in the retaining tab. On and off takes about two seconds each time.
Griffin Armament claims that the suppressor is full auto rated and can be run on barrels as short as 10.5″.
