Today’s Topics:

1. Sound Signature Review 6.198 – Microtech Defense R2K9 on the HK P30L. It’s been about 5 years or so, give or take, since this silencer hit the market. It’s about as old as PEW Science. Was it ahead of its time? Or was it simply a diamond in the rough that folks glossed over? Check out this interesting modular pistol silencer and the fully-featured accessory package in this Member Funded research – intro talk for today’s white paper. (00:08:14)

2. The SIG MCX, or “LVAW” and its variants. 6.75” Rattler LT recreational use continues. Really hammering the system with subs and supers. And, have some ideas for heat mitigation. Let’s continue the discussion we had last week. (00:28:06)

1. Sound Signature Review 6.197 – Combat Application Technologies CAT KK on the 10.3 5.56 MK18. Small silencer with performance that was a little surprising. Hybrid design advanced silencers continue to push the envelope. Technical discussion for the whitepaper published last week.

a. Intro and physical characteristics. (00:08:26)

b. Design, system performance, and mount considerations. (00:17:11)

c. Performance extrapolation. Possible? (00:45:31)

2. The SIG MCX, or “LVAW” and its variants. 6.75” Rattler LT recreational use has been underway. Some interesting findings to share from a recent range outing. Approximately 1000 rounds of various ammo brands, subs and supers, fired from the system with the SIG SD handguard. Practical? Absolutely not, if you shoot a lot. Here are some thoughts. (00:54:08)

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)
