Episode 285 - 5.56 Silencer Backpressure Hazards and Whiskey Quebec TPMS Structures (03-DEC-2025)

Today’s Topics:

  1. Sound Signature Review 6.206 – Battle Born Supply Co. Whiskey Quebec 5.56 on the 14.5-in mid-length gas M4. The Purged version was evaluated in Report 6.207. This is the technical discussion accompanying those two analytical test reports, exploring the performance efficacy of Triply Periodic Minimal Surface (TPMS) baffle structures.

    a. Intro and recap (00:06:56)

    b. Basic TPMS geometry and applications to silencers, pros and cons (00:17:20)

    c. Overall technical observations (00:29:25)

    d. Conclusions (00:47:24)

  2. Silencer Hazard Map Brief 8.1.5 – SilencerCo Saker 556 vs. the HUXWRX FLOW 556k on the MK18. Due to popular request to showcase a high backpressure conventional 5.56 silencer, we went back into the archives, all the way to Report 6.53 from 2021 and ran the test results through the PEW-SOFT HD Hazard Mapper. Does this Silencer Hazard Map for the Saker 556 help illustrate operator risk when using these types of legacy silencer designs? Can a HUXWRX FLOW 556k save you? Maybe not. (00:50:17)

Episode 284 - Battle Born Supply Co. Whiskey Quebec 5.56 Testing Intro and Hazards (26-NOV-2025)

Today’s Topics:

  1. Sound Signature Review 6.206 – Battle Born Supply Co. Whiskey Quebec 5.56 on the 14.5-in mid-length gas M4. Inconel. 3D printed. Are there folks out here using 3D printing for things that are simply not machinable by traditional methods? Yes. This family of silencers is one of them. Let’s explore the performance of Triply Periodic Minimal Surface (TPMS) baffle structures in the intro to this report published with today’s episode. (00:08:06)

  2. Sound Signature Review 6.207 – Battle Born Supply Co. Whiskey Quebec 5.56 Purged on the 14.5-in mid-length gas M4. This is the high(er) flow rate brother to the silencer we just discussed. Both silencers have high early-time flow rate. What if you increase the late time flow rate? Let’s check out the performance differentials in the intro to the second report published today. (00:27:16)

  3. Silencer Hazard Map Brief 8.1.4 – Analytical test reports too long for you? Maybe you don’t have time to dig into them yet before you eat turkey and pumpkin pie? Not a problem. Hit this Brief for a succinct look at how the Whiskey Quebec 5.56 (Purged and non-Purged models) project hazards to personnel, spatially. Pictures are good! (00:34:15)

Episode 177 - PWS BDE 762 on .308, 3D Printing, and Impulse (06-SEP-2023)

Today’s Topics:

  1. Latest public laboratory white paper – Sound Signature Review 6.121 – Primary Weapons Systems PWS BDE 762 on .308! Short tech brief for this modular rifle silencer. Haven’t seen modular rifle stuff in a minute! (00:10:16)

  2. Another PEW lab quiz has come and gone. Per feedback, they stepped up the difficulty. Did you persevere? Or did you succumb to the pressure? Haha – let’s go over the answers! (00:44:06)

Episode 125 - HUXWRX FLOW 556K and SCAR Update #6 (10-AUG-2022)

Today’s Topics:

  1. Sound Signature Review 6.83 – the HUXWRX FLOW 556k on the 5.56 MK18 AR15 SBR – technical discussion. Interesting performance! (00:07:34)

  2. SCAR Project – micro-update #6. Hitting the 800-round mark; experience so far, suppressed, and gas dynamics. (01:25:39)

  3. The suppressed small arms landscape is changing. What is next on the horizon? Many PEW Science members have shared their thoughts with me, regarding emerging technologies. How far out are we, from new innovation? (01:42:50)
