Episode 280 - Otter Creek Labs Infinity AK Testing Intro and Blast Overpressure (22-OCT-2025)

Today’s Topics:

  1. Sound Signature Review 6.204 – Otter Creek Labs Infinity on 16.3-in and 12.6-in AK systems. The Infinity it one of the most characterized silencers by the PEW Science Laboratory. With the addition of these two tests, it brings the total amount of Infinity record numbers in the Rankings to 11. In this test program, the vented 7.62 end cap was used, exclusively. Could AK suppression be the Infinity sweet spot? This is an introduction to the white paper published today. (00:08:37)

  2. Quick note about blast overpressure. There are hundreds of reports at pewscience.com characterizing blast overpressure from suppressed small arms. What is it? Well, you actually already know. (00:25:07)

Episode 271 - OCL Infinity M4 Tech Talk and CAT KK MK18 Intro (13-AUG-2025)

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)

Episode 259 - Otter Creek Labs Infinity Technical Performance and Sylvan Arms Intro (14-MAY-2025)

Today’s Topics:

  1. Big shout-out to Mark and the Hunt Backcountry Podcast! Mark invited me to speak with him a while back about “Suppressor Science, Selection, and Sound” in sort of a “hunting centric” fashion. Please check out Episode 523 of their podcast when you can! (00:09:18)

  2. 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? Technical discussion for this technical paper published 30-APR. (00:11:37)

  3. Sound Signature Review 6.186 – Sylvan Arms SA30TI with supersonic .308. Classic design; smaller diameter. Simple and secure mount. Let’s take a look at this 30 caliber silencer in this introductory topic to the whitepaper published today with this episode! (00:37:36)

  4. Sound Signature Review 6.187 – Sylvan Arms SA223TIS on the 14.5 M4. The shorter, dedicated 5.56 silencer to complement the SA30TI. Another classic, small diameter system with the same simple ACME thread secondary-retention. This is the introductory topic to the second whitepaper published today with this episode! (00:46:16)
