Watertown, WI – May 30th, 2025–
Griffin Armament’s history with metal printed suppressors goes back to 2008 with prototype applications. We felt the technology was neither developed nor cost-effective enough to be viable and publicly accepted for a long portion of that time. The hope of more manufacturing applications in other industries being supported and costs of equipment reducing, as well as capabilities and technology increasing, were considerable factors in waiting for the technology to mature. Griffin’s Optimus® 6 is our first printed production suppressor. The Optimus® 6 is a powder metal additive manufactured 6mm capable suppressor optimized for the 5.56mm AR-15 platform. Complex internal baffle geometries were painstakingly prototyped and tested to yield a suppressor with low system backpressure and exceptional flash reduction.
The Optimus® 6 is constructed entirely of 17-4 H900 Heat-Treated Stainless Steel, and is available in three mounting variations: DUAL-LOK®, Griffin Taper Mount, and an industry-standard HUB (1.375×24 TPI) interface for use with HUB mount adapters. The printed baffle stack is welded to a machined rear housing that bears the serial number making warranty and repair work performable without the need to resubmit the lengthy Form 4 process for a new serial number. This is a problem with fully printed cans that hasn’t been adequately addressed in the market. A 1.73” outer diameter was chosen to allow increased internal volume – contributing to its sub-140 dB SPL.
Flash reduction is often seen as more important than sound reduction for military and LE applications, but both categories tend to suffer when creating suppressors with very low-restrictive baffling. The Optimus® 6 endcap was developed to address the inherent increase in flash signature coupled with LBP suppressors. This unique quad-prong end cap features complex internal and external flash-hiding geometries to bring highly competitive flash suppression to the LBP suppressor market. The Optimus® 6 is a thoughtful combination of traditional and new technologies yielding a low backpressure suppressor that is easily repairable, highly durable, at a reasonable weight, while exhibiting top of the line sound and flash reduction at a lower price than many other printed suppressors on the market.
“Making suppressors that have good acoustic performance, with a high quality to cost ratio has been important to Griffin over our 20 years in industry. We’ve seen the demand grow over the past number of years for suppressors that run more transparently to the firearm they are attached to- minimizing backpressure being one of the ideal solutions. Additive manufacturing has advantages and disadvantages that vary depending on the process. In some aspects, it improves the ease with which a geometry is created, and in others, there are limitations like low overhang angles that are impossible depending on the method used. We are happy to introduce the Optimus 6 to market, and to begin using additive manufacturing for some of our suppressor designs. The Optimus 6 is one of the most-performing 5.56mm cans I have used. One of the first customers to see the suppressor was a Law Enforcement department that liked the suppressor enough to place a large pre-order. Several of the people who I work with at Griffin were impressed with the suppressor and made the decision to make it their free suppressor for 2025, as one of our employee benefits is a free suppressor every year an employee completes with the company, if the employee wishes to take advantage of that benefit.”
