ALL NFA RULES APPLY. 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 RECCE (MOD4) 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 Recce 7 is fully CNC machined, and tig fusion welded from 17-4 stainless steel for maximum thermal transfer and unparalleled strength and durability. Every component in the Recce 7 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 Recce 7 a terrific value. Overall SPL on a 12" 300BLK with Remington 220 Subsonic is 123DB, quieter than some 22 rimfire suppressors on the market. Whether hunting your favorite game or rucking on a long range patrol the Recce 7 is the right tool for the job.
