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 257 - Otter Creek Labs Infinity subsonic 300 BLK Testing Intro (30-APR-2025)

Today’s Topic:

  1. Sound Signature Review 6.185 – Otter Creek Labs Infinity with subsonic 300 BLK. The Q mini Fix – an 8-in barrel proving ground, from the beginning. How does the versatile Infinity handle subsonic ammunition combustion out of a relatively short barrel? How does its performance compare with some older designs and some purpose-built 300 BLK designs? Can it hang? Introductory discussion for this technical paper published today. (00:05:49)

Episode 213 - PEW Science Listener Questions - FRP, Materials, Durability, and Testing (30-MAY-2024)

Today’s Topics:

  1. Listener Questions are back! Will we finally finish the 6th solicitation? Will we surpass the 500-question mark on the podcast?! All signs point to definitely maybe. (00:07:31)

  2. Testing is difficult. Those that work in various experimental and research fields of engineering and other disciplines understand this first-hand. Overcoming adversity is also difficult. Nonetheless, we are excited to share that some great discoveries are occurring in the PEW Science research pedigree! (00:57:09)
