The EXPLORR® series was built on years of prior experience and R&D with tubeless designs. Relatively unknown, Griffin started pushing the limits on modern suppressor engineering when in 2010, they designed the first tubeless silencers in the US. Tubeless designs although relatively featureless, provide the most optimal strength to weight ratio of any construction method. With a solid background in tubeless suppressor engineering, Griffin sought to push the limits of what was capable by creating the EXPLORR® series of suppressors that hit titanium weights with a more durable material. Lower weight means smaller point of impact shift, higher unsupported position accuracy potential, and less fatigue to the user when carrying equipment.    

The current version is the EXPLORR® (Gen 2). This page is dedicated to the EXPLORR® (Utility Mount - .300).  

It features our utility patented ECO-FLOW™ baffle system offering the apogee of multi-caliber sound performance. This baffle system reduces back pressure which alleviates much of the blow back through semi auto actions providing a more comfortable experience to the end user. This baffle system is tuned such that performance at the muzzle of the suppressor and the ears of the operator are balanced for a uniform and low sound signature in the immediate vicinity of the shooter. 

Elite tactical units requested minimal flash signature and Griffin responded by developing a low-profile flash reducer integral to the suppressor end cap. This flash reduction device adds only a couple tenths of an inch in length and reduces first round flash considerably vs flat end cap (featureless) designs.  

Another notable improvement in the EXPLORR® (Gen 2) family is the integration of the backward compatible Taper Mount-RI™ interface (Rapid Index). The Griffin Taper Mount interface is a gold standard in the industry, providing secure attachment, and unbeatable accuracy to consumers for over a decade.  This interface has been improved however, being 3X faster to mount than the original by engineering a precision indexing feature in the interface and using fewer machined thread rotations in a more optimal position within the body.  The original Griffin Taper Mount took roughly 15 seconds on average to mount and the new system can be reliably mounted in 5 seconds.  Accuracy, and POI shift have been improved while the secure attachment the Griffin Taper Mount is known for has not changed, resulting in a next generation Taper Mount-RI™, an ideal system built on over a decade of taper mount manufacturing and research. 

The EXPLORR® is fully CNC machined, and is now laser welded to  reduce weight but increases the overall durability of the suppressor. The benefits of laser welding include a much deeper penetrating, evenly distributed precision weld to greatly enhance the strength of the attachment bond, while also creating a more polished appearance to the exterior of the suppressor. 

Every component in the EXPLORR® is manufactured from solid, high temperature corrosion resistant 17-4 Stainless Steel, and then H900 heat treated to ensure maximum service life is provided. Years of internal testing has found 17-4 stainless steel to provide longer service life than 718 Inconel, the prior market leading alloy. 17-4 stainless is also twice as strong as cast Stellite 6, used by some industry companies. A Taper Mount EZ Brake is included, making the EXPLORR® a terrific value. 

Slightly heavier than its Taper Mount cousin, the Utility Mount version is suited to those seeking to get the most versatility out of their next adventure.

    First Silencer I Ever Bought

    Published by Henry on 29th Mar 2024

    So this was the first silencer I ever purchased. I was nervous at first, because there are so many silencers to choose from. Someone at my LGS recommended Griffin. After some research I decided this would be my choice. Let Me tell you, this not only makes my rifle quieter but also makes it a softer shooter. I'm super happy with my purchase. Being from Milwaukee, I am happy to support a Wisconsin business. I can't wait to buy my next can! Probably the Revolution 9, Resistance 9 or the Optimus. I would definitely recommend.

    One of the better options out there

    Published by Gabe on 28th Jul 2023

    I bought this suppressor because it was going to live on a 7.62x39 AK pistol as a fun range toy. I specifically bought this model because it lands in the goldilocks zone of not too short or too long. On my scale with the ASR 1.375x24 mount it weighs in at 14.5oz at 6⅝ths of total length. Not bad all things considered, I have approximately 4,500 rounds through the suppressor and it keeps chugging along despite my crude firing schedule. One thing to note, it being a tubeless design, after 15 or so shots out of the rifle the suppressor does begin to noticably glow under night vision. That's not the fault of GA themselves, nobody can cheat physics, but it is something to be aware of. Sound performance is pretty good, it tames the fireball out of my 12" 7.62x39 gun very well and performs decently on a 11.5" 5.56 gun. Back pressure is minimal, no gas escapes out of the AK or AR, which makes this a very pleasant suppressor to use. All in all, I'm very happy with my purchase. It performs excellently and it was exactly what I was looking for. One negative I will say is that I'm not a fan of the cerakote finish. Because the suppressor heats up so quickly, it does break down pretty quick and begins to burn/flake off around the center point of the suppressor. It's a cosmetic thing, nothing I own is pretty looking, so I myself don't care at all. Just a little note.
