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)
