1. New Sound Signature Review? That’s right. SSS.6.125 – the Resilient Suppressors Jessie’s Girl on .22 bolt-action. The last time you saw rimfire data and analysis from PEW Science was on PEW Science Silencer Sound Standard launch day. Since that historic day, we have given you a wide variety of information. Let’s circle back to the quietest systems now that you have context! Let the battle begin. (00:11:14)

2. Speaking of battles – just when you thought it was safe to suppress the AR-15. Do you have time to discuss 14.5 midlength gas? I hope so, because you should pull up a chair, get comfortable, and maybe throw out a lot of things you thought you knew about suppressing the AR-15. Fighting battles on multiple fronts is going to be the theme going forward. Good luck. (00:34:02)

3. How are we able to provide consistent, topical information for almost 4 years running, continuously, accurately, and with exceptional quality and relevance? With PEW Science Member support, that’s how. Behind every monumental effort is a backbone of support, and the grassroots PEW Science Army is stronger than ever. From dealers, to distributors, to manufacturers, to consumers, to families – everyone is banding together to educate the masses on the wonderful world of suppressed small arms. Cheers to you – it’s working! (00:53:40)

3. Huge thank you to PEW Science members – this effort has been grassroots from the beginning and that continues well into our third year of operations. From the consumer, dealer, manufacturer, and distributor support – to our professional lab testing clients – you have all combined your forces to create the greatest truly independent third-party testing and analysis database ever published. Kudos to all of you! (01:14:45)

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)

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.

2. The night time is the right time! What happens when you shoot a Flow-Through titanium silencer on a 14.5 inch 5.56 machine gun at night? Does it flash? Does it spark? What about under night vision? What about with thermal? The humanity! I’ll give you some of my recent field experience with the HUXWRX FLOW 762 Ti from this past weekend. (00:20:31)

3. Independent laboratory testing of silencer sound signatures – coupled with engineering analysis. Why do we do it? It’s more than just for trust and mitigating conflicts of interest.
