Episode 300 - AAC 762-SDN-6 Testing Tech Discussion and HK USP 45 Tactical Match LEM Hybrid (08-APR-2026)

Today’s Topics:

  1. Sound Signature Review 6.220 – The new AAC 762-SDN-6 on the 14.5-in SR-25. First released in 2011, this is a brand-new iteration of this famous silencer refreshed for 2026. High flow rate, high performance, and updated for the modern age. Technical discussion of last week’s report.

    a. Intro and recap (00:07:07)

    b. 762-SDN-6 overview (00:14:03)

    c. 762-SDN-6 silencer design (00:21:33)

    d. Hazard Map Brief 8.1.17 (00:30:39)

    e. System performance (00:38:10)

    f. Overall thoughts (00:50:05)

  2. Sound Signature Review 6.221 – The new AAC 762-SDN-6 on 300 BLK bolt-action. Originally developed to suppress multiple cartridges, 300 BLK was certainly advertised as one of the strengths of the original design. This new iteration is particularly strong, even with a high flow rate. Technical discussion of last week’s report.

    a. Intro and recap (00:54:36)

    b. Hazard Map Brief 8.1.18 (00:57:58)

    c. System performance (01:06:24)

    d. Overall thoughts (01:17:49)

  3. Carrying full size guns is cool. We shoot them because they are really fun to shoot. So why not carry what you like to shoot? HK USP 45 Tactical (the MK23 Compact) is excellent. Match LEM Hybrid? Yes, please. (01:20:30)

Today’s Topics:

  1. Sound Signature Review 6.219 – The Magco Arms EDS-30L on 20-in 308 bolt action. Extreme performance in an 8-inch length – it’s great to see newcomers to the space! Let’s go through the technical overview of last week’s publication.

    a. Intro and recap (00:09:29)

    b. EDS-30L overview (00:18:14)

    c. EDS-30L silencer design (00:23:04)

    d. Hazard Map Brief 8.1.16 (00:35:08)

    e. System performance (00:42:47)

    f. Overall thoughts (00:59:24)

  2. Sound Signature Review 6.220 – The new AAC 762-SDN-6 on the 14.5-in SR-25. No, it is not 2011! It is, in fact, 2026 – and this is a brand-new iteration of this famous silencer. High flow rate, high performance, and updated for the modern age. This is an introduction to the first of two reports published on this silencer today! (01:01:04)

  3. Sound Signature Review 6.221 – The new AAC 762-SDN-6 on 300 BLK bolt-action. What a time to be alive. A new AAC silencer being tested on a Q rifle? Historic event, and boy is this silencer a switch-hitter. It is not often we see high performance with subsonic 300 BLK from high flow rate silencers. This is an introduction to the second of two reports published on this silencer today. (01:10:18)

Episode 254 - Dead Air Wolfman Testing and MP5 Performance Research (09-APR-2025)

Today’s Topics:

  1. Sound Signature Review 6.182 – the Dead Air Wolfman on the HK SP5 – in both long and short configurations. Prolific (and also misunderstood) submachine gun silencer. Let’s dive into the technical discussion of the data and analysis published last week.

    a. Introduction (00:07:46)

    b. Physical Characteristics (00:17:31)

    c. Technical Performance – Long Configuration (00:27:10)

    d. Technical Performance – Short Configuration (00:44:04)

    e. MP5 Suppression Performance Comparisons (00:51:09)

  2. Pending Member Research – MP5 suppression. The Quietest 9mm Subgun Silencers. We all know and love the MP5 platform. It is, perhaps, one of the most famous and refined subgun silencer hosts that we have in small arms. So, which silencers help it to perform at its greatest potential? Which have the best signature reduction and tone? Ongoing in-depth signature research that will be delivered exclusively to PEW Science Members. Thank you for your support! (00:58:35)
