They took forever, but the first run of M4SD II's are finally here.
Because a lot of people are asking, I'll recap- these are fully welded 316 Stainless steel and high strength 17-4 PH stainless steel, with a 100% heat treated 718 inconel baffle system. They weight 18.8 ounces, they have wire EDM bores and high tolerance machined mounting systems. This technology allows them to reduce the sound signature by 97% and to have minimal and repeatable POI shift. They are really top of the line.
The flash suppressor in the photo is just spun on- it's not mounted with the wrench flats vertical which is the case for all the other devices (A2, M4SD II comp, M4SD II Brake, M4SD II flash comp). So the locking gate will actually be oriented left or right of the gun for most end users.
Thanks to the pre-order people for their incredible patience and for making the run possible. We appreciate you guys helping a couple veterans realize a dream to make great sound suppressors.
Every suppressor comes with a free 3x2 flag sized velcro Griffin Armament patch made by Mil-Spec Monkey. Thanks to Mil-Spec Monkey for the patches and for facilitating the design and production of a nice companion product!
