Griffin Armament GAOP6TM-W Taper Mount Optimus 6 6mm Fits 6.59" Long 17-4 Stainless Steel Cerakote
The Griffin Armament Optimus 6 Taper Mount is a 6mm suppressor built for shooters who refuse to compromise between sound reduction and shooter comfort. If you run a 5.56mm or 6mm platform and want serious flash control without the brutal backpressure that chokes out your rifle's reliability, this taper-mount can is purpose-built to solve both problems at once. Griffin's additive-manufacturing (3D-printed) core paired with a machined 17-4 stainless steel exterior and quad-tine flash hider delivers the kind of balanced performance that separates serious suppressors from the rest.
What makes the Optimus 6 stand out is Griffin's commitment to actual engineering over buzzwords. The high-flow baffle stack keeps backpressure low—meaning your bolt cycles soft, your gun stays reliable, and you don't get blasted by gas in the face. That matters on an 11.5" short-barrel rifle more than anywhere else. The quad-tine end cap was tuned alongside the baffle stack specifically to crush muzzle flash, hitting levels of flash reduction rare in low-backpressure suppressors. At 1.73" in diameter and 6.59" long, it integrates without turning your rifle into a tank.
This Taper Mount model comes ready to go with an included EZ-Brake (.22 cal 1/2-28), so you can mount it same-day on compatible platforms. The whole can is 17-4 stainless steel—ultra-strong and corrosion-resistant—with a machined finish that looks clean and professional, not like the visible printing layers you'll see on cheaper printed suppressors. Griffin backs it with a Perpetual Lifetime Warranty because they stand behind their work. Full-auto rated, so it'll handle whatever you throw at it.
Griffin spent years waiting for additive-manufacturing technology to hit the price and reliability sweet spot before entering the suppressor market. Now that it's here, their expertise shows. This isn't a budget compromise—it's a feature-packed suppressor at real value, engineered by a company that's been prototyping and refining suppressors for decades.

Frequently Asked Questions
What's the difference between low backpressure and traditional suppressors?
Low-backpressure suppressors like the Optimus 6 use a high-flow baffle design that lets gas escape more efficiently, reducing the pressure spike that cycles your bolt. On short-barrel rifles especially, this means softer recoil, cleaner cycling, and less gas in your face—while still delivering serious sound and flash reduction. The tradeoff used to be worse suppression, but Griffin engineered the quad-tine end cap and baffle stack together to maintain excellent performance without the backpressure penalty.
Will this suppressor work on my 5.56mm rifle?
Yes. The Optimus 6 is optimized for 5.56mm platforms and is also capable on 6mm projectiles. If you're running standard 5.56mm ammo on an AR-15 or similar rifle, this is your suppressor.
What comes in the box, and what do I need to buy separately?
This Taper Mount model includes the suppressor and an EZ-Brake (.22 cal 1/2-28) muzzle brake. You do not need to purchase additional mounting hardware—you're ready to install on a compatible taper-mount-threaded barrel. Note: if you were looking at a Utility Mount (HUB) model, those require a separate muzzle device and hub insert (sold separately); this taper-mount variant does not.
Is this suppressor durable enough for rapid fire or full-auto?
Yes. The Optimus 6 is rated for full-auto use, meaning it's built to handle sustained high-rate-of-fire applications. The entire can is 17-4 stainless steel, and the laser-welded baffle core and mount system are designed for durability. Griffin also backs it with a Perpetual Lifetime Warranty, including coverage for baffle strikes or other catastrophic failures.
