Episode 263 - CAT RAT 300 BLK MCX Testing Intro and PWS BDE 22 Tech Discussion (18-JUN-2025)

Today’s Topics:

  1. Sound Signature Review 6.190 – the Primary Weapon Systems PWS BDE 22 on the subcompact Beretta 21A (Bobcat). A little rimfire palate cleanser for you! Monocore, 3D printed, user serviceable. Technical discussion of this lightweight silencer’s performance that was characterized in last week’s report (00:09:09)

  2. Semiauto 300 BLK is here! Sound Signature Review 6.191 – Combat Application Technologies CAT/RAT on the 6.75-in SIG SAUER MCX AR-18 consumer retail LVAW analog. The CAT RAT is modular – but not how we typically see. This is also more than an end cap change. Let’s introduce both this new test host and this new silencer system designed specifically for the SIG MCX and Rattler family of PDWs.

    a. Topic Intro (00:35:33)

    b. SIG MCX System Intro (00:39:40)

    c. CAT RAT System Intro (00:51:33)

Episode 176 - CAT ODB on 5.56, PWS BDE 762 on .308, and more Quizzes! (30-AUG-2023)

Today’s Topics:

  1. Latest public laboratory white paper – Sound Signature Review 6.120 – CAT/ODB/A1/718 on the 5.56x45mm MK18 SBR. Short tech brief for you, as is our new routine. Controversial silencer? It just might be – because of physics. (00:09:49)

  2. The PEW Lab is releasing another white paper this week. The data has passed review and it’s for Primary Weapon Systems - the PWS BDE 762 on bolt-action .308. The BDE 762 is a modular silencer and a hybrid DMLS / subtractive design! Is DMLS the future of silencers? No, not of all silencers. Of high-performance silencers? Yeah, probably. (00:44:29)

  3. Did you folks get last week’s PEW lab quiz correct AND the weekend quiz? There were two! Let’s go over the answers. You folks are some smart cookies! (00:55:27)
