Today’s Topics:
1. Today we are launching Section 8 of the Silencer Sound Standard: SSS.8 – Advanced Silencer Research. Outside of public view, PEW Science performs a significant amount of testing and engineering analysis on a variety of systems; most of which is never published. Not everything has to remain behind closed doors. Section 8 of the Standard presents further research advancements that are cleared for public release. (00:04:02)
2. The first section in Section 8 is live today with this episode! The first report in this section is SSS.8.1.1 - Introducing PEW-SOFT HD Hazard Maps. The Suppression Rating has made you powerful. Now, you will become even more powerful, as you navigate personnel hazards from silencers in both the free field and near reflecting surfaces; everywhere. We’ll walk you through the report in today’s talk. Here is an outline:
a. Introduction (00:08:22)
b. 8.1.1.1 - Dimensional Variations (00:20:12)
c. 8.1.1.2 - Free Field Data, and You (00:22:55)
d. 8.1.1.3 - PEW-SOFT HD Hazard Mapper (00:31:19)
e. 8.1.1.4 - MK18 Case Study: 556-RC2 vs. 556-RC3 vs FLOW 556k (00:41:04)
f. 8.1.1.5 - Reflections - Moving outside of the Free Field (01:02:20)
g. 8.1.1.6 - Conclusions and Acknowledgements (01:07:24)

Episode 271 - OCL Infinity M4 Tech Talk and CAT KK MK18 Intro (13-AUG-2025)
Today’s Topics:
1. Sound Signature Review 6.196 – Otter Creek Labs Infinity on the 14.5-in mid-length gas M4A1. You’ve seen this durable, versatile silencer on everything from 7.62 NATO to subsonic 300 BLK to short barrel 5.56 NATO. What have we learned about the Infinity, and how its technology works? How does the hybrid Otter Creek Infinity technology respond to lowering blast load input severity with 5.56? Very interesting findings – this technical talk covers them.
a. Big Picture and – barrel length? Why does it matter, anyway? (00:09:04)
b. Solid 5.56 End Cap Performance (00:24:34)
c. Vented 5.56 End Cap Performance (00:50:32)
d. Vented 7.62 End Cap Performance (00:53:28)
e. Performance comparison and nuance (00:56:28)
2. Sound Signature Review 6.197 – Combat Application Technologies CAT KK on the 10.3 5.56 MK18. Hybrid design advanced silencers continue to push the envelope. The past 5 years have been full of tremendous performance gains, particularly in high pressure supersonic cartridge suppression. As the competition continues, how does form factor fit into the mix? The CAT KK, and others, bring that discussion to the forefront. Introductory talk for the whitepaper published today. (01:13:25)
