GRIFFIN Explorr 300 EU3 Universal Mount 1.375×24

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® U-300 (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® U-300 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® U-300 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® U-300 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.
