The CAT/JL/A1 (CAT JL) is a lightweight and extremely advanced 30 caliber rifle silencer that exhibits significant sound signature suppression performance. For its size and weight envelope, the JL’s performance is even more extreme. Notably, the CAT SNIPER2 technology in the JL silencer appears to balance a high early time flow rate with continuous and consistent stagnation relief throughout the silencer, resulting in not only high performance first round shot suppression, but also some of the most consistent performance evaluated on this host weapon system by PEW Science, to date.

In this review, the CAT JL performance metrics depend upon suppressing a supersonic centerfire rifle cartridge; no easy task. How would the silencer perform on your .308 deer rifle?
