Sig's new cans, they just murdered the competition in price, sound, back pressure, and availability

In this video, Rob Orgel—combat veteran, former military instructor, and long-time suppressor tester—puts Sig Sauer’s entire new suppressor lineup through uncompromising, head-to-head testing against the previous kings of each category. SIG’s newest suppressors tested include: HEXIUM 556 Titanium HEXIUM 556 Inconel HEXIUM 300 HEXIUM 762 ENDURE 30 TIN CAN These were tested directly against the long-standing benchmarks, including the CAT JL, two B&T suppressors (TI-REX Compact with reflex and Stille), and the PTR Vent 1—formerly regarded as one of the quietest suppressors ever produced. Testing begins with 5.56 using 11.5-inch MCX rifles fired side-by-side to eliminate variables. This includes a direct Inconel vs titanium comparison between the two HEXIUM M556 variants, followed by quantified back-pressure testing. The back-pressure results were unexpected and shocked everyone involved, including SIG’s own program director. Once back pressure was fully measured and documented, testing moved into: 308 on 18-inch bolt-action rifles 300 Blackout, both subsonic and supersonic Suppressors were deliberately swapped between rifles and firing positions, and evaluated by multiple listeners to eliminate confirmation bias. When sound performance was too close to confidently call, ammunition was changed to force additional delta and reveal true performance differences. Ammunition used: 5.56: PMC X-TAC 55gr FMJ 300 Blackout: SIG Sauer subsonic and supersonic .308: Winchester ball, followed by Federal Gold Medal Match 175gr Across 5.56, 300 Blackout (sub and super), and .308, one suppressor repeatedly separated itself from everything else tested—the HEXIUM 300. It matched or exceeded the sound performance of every 30-caliber suppressor in the test, including the CAT JL, while weighing the same as the PTR Vent 1, costing less than both, and being readily available in stock. The HEXIUM 300 was not only quieter to the ear across platforms, it also demonstrated exceptional nighttime performance with minimal flash. Its 5.56 counterpart, the HEXIUM M556, was equally impressive and now firmly sits within Rob’s top three 5.56 suppressors currently available. What makes this result undeniable is consistency. The HEXIUM 300 dominated regardless of rifle, ammunition, caliber, or shooting condition. When doubts arose, testing was repeated, rifles were swapped, positions inverted, and listeners rotated. The outcome did not change. After testing, remaining questions were not about performance—but about design intent versus unexpected excellence, prompting a follow-up interview to better understand how SIG achieved this level of performance so quickly, and why a few of their newer models showed more niche-specific results. Conclusion driven by data: if Rob lost all 204 suppressors in his collection today, the first suppressor he would repurchase is the SIG HEXIUM 300. It is quieter than any 30-caliber suppressor he owns, exceptional on 5.56 and 300 Blackout, competitively priced, widely available, and dominant both day and night.
