GRIFFIN SUPPRESSOR M4SD L TUBELESS 22CAL BLK
The new M4SD-L 5.56mm suppressor keeps this tradition in mind by incorporating a perfect combination of many beloved suppressor technologies Griffin is known for : GATE-LOK mounting system, tubeless laser welding, ECO-FLOW baffle tech, and the Pressure Reduction Cap.
This suppressor utilizes the GATE-LOK QD mounting system, one of the fastest on the market, which allows attachment compatibility to mil spec A2 Nato compensators as well as Griffin’s proprietary, performance-rich GATE-LOK muzzle device options.
Griffin Armament was the US pioneer of tubeless suppressor technology when in 2010 nearly the whole Griffin centerfire suppressor line was engineered this way. If lower system weights are desired, tubeless construction is ideal, as traditional double walled construction is omitted. Deleting the textured outer tube that the GATE-LOK family is historically known for, saves weight but imposes other engineering difficulties which need to be overcome. With over a decade of tubeless suppressor manufacturing experience, Griffin has matched or exceeded the durability and useful service life of traditionally-constructed suppressors in a weight-saving, tubeless design. M4SD-L suppressors are manufactured using 17-4 stainless steel, from industry leading suppliers. Griffin utilizes cutting edge CAD design, industry leading tooling and machining practices, and integration of laser welding to provide unmatched strength and durability without the need for a heavy, tube-over design.
Balancing internal flow with optimized sound suppression is also fundamental to suppressor engineering, as that is the chief reason to use the items. Griffin has integrated its patented ECO-FLOW baffle design into the M4SD-L which allows gasses to flow through the suppressor reducing blow-back in semi automatic and fully automatic operating systems. This provides the end user with reduced gas and sound pressure at the shooter’s ear and face, without sacrificing sound and flash suppression.
The patent pending Pressure Reduction Cap features high performance internal and external flash reducing features, as well as optimally tuned gas vents which not only enhance flash reduction even further but also improve sound performance in conjunction with the ECO-FLOW baffles.

Suppressors and SBR’s are legal to own in 42 states and growing. Suppressors can be purchased through an authorized dealer but are regulated by the national firearms act [nfa] branch of the bureau of alcohol tobacco firearms and explosives. This means there are a few extra steps for purchasing a suppressor compared to a regular firearm. The following outlines what you need to legally purchase a suppressor.
Requirements
Be a resident of a state where suppressors are legal
Be at least 21 years of age
Be a united states resident
Be legally allowed to purchase a firearm
Pass an atf background check
Ensure your local chief law enforcement officer gets a copy of your form 4
Materials to purchase a suppressor, you will need to find an authorized dealer in your area. Once you find the suppressor you want, the dealer will assist you in filling out a form 4. This is the form you will send into atf along with the following:
Atf form 4 (duplicate)
Fbi form fd-258s in black ink
Passport photos
Ate form 5320.23 (if using a trust)
PRODUCT SKU: GA-M4SDL
