Product Description
Griffin Armament knows suppressors. Their passion is evident with every silencer unveiling, as each unit is more impressive than the last. Always looking to improve upon excellence, the M4SD-II is the fourth installment of their flagship suppressor. This quick-detach 5.56mm rifle can was designed to provide the optimal combination of lightweight, durability, and peak performance.

Founded by two military brothers out to preserve firearm enthusiasts’ hearing, Wisconsin’s Griffin Armament utilizes computer-based designs and highly-tested products to suppress guns of all calibers. Their mission is admirable, as is the team’s goal of passing along savings to suppressor users. The revamped M4SD-II unit is yet another example of this practice.

Further Intel
Because Griffin prefers the strength and wear-resistance of stainless steel, their M4SD-II can is crafted entirely of this metal. At a length of 6.6” and sporting a sound reduction of 35 dB… Good call on their part. Moreover, at the request of elite tactical units, the integrated flash suppressor front cap further reduces flash signature, creating enhanced covertness. With a unique, high-efficiency baffle system, Griffin truly thought of everything while rigorously testing this silencer. It even offers shooters a wide range of mounting options, employing the M4SD family-specific SDQD mounting interface. This true QD mechanism allows one-handed attachment and removal with relative ease. Being full-auto rated and compatible with NATO muzzle devices helps keep your ammo budget as healthy as possible, too!
