Episode 328 - Tuna Cans Blackfin XL Technical Performance Discussion (28-OCT-2026)

Today’s Topic:

  1. Sound Signature Review 6.241 – Tuna Cans Blackfin XL 12-baffle and 9-baffle on the 300 BLK subsonic bolt-action rifle. The economy evaluations continue – we first evaluated this stepped cone design on the 5.56 M4. How does this type of baffle perform with much lower pressure? And as a .375 caliber silencer, does over-bore induce performance loss? And what about FRP? Technical discussion of last week’s double-header report. (00:06:21)

    a. Intro to the Blackfin XL and Blackfin L (00:16:34)

    b. Blackfin XL general overview (00:19:26)

    c. Blackfin XL silencer design and functional physics (00:29:40)

    d. Blackfin XL and L Hazard Maps in Silencer Hazard Map Brief 8.1.38 (00:37:29)

    e. Technical performance discussion – suppressing subsonic 300 BLK (00:43:08)

    f. Performance Comparisons and Overall thoughts (00:57:38)

Episode 327 - Tuna Cans Blackfin XL Testing and OCL Infinity 556K M4 Tech Discussion (21-OCT-2026)

Today’s Topics:

  1. Sound Signature Review 6.240 – Otter Creek Labs Infinity 556K on the 14.5-in 5.56 M4. OCL Infinity technology is one of the most characterized in the research. The technology was shown to scale with barrel length in the .30 caliber bore size. What happens with the dedicated bore 556K on the M4? Technical discussion of last week’s report and tone study. (00:06:25)

    a. Short re-intro and overview of the Infinity 556K (00:10:30)

    b. Infinity 556K MK18 and M4 performance differentials (00:12:54)

    c. Members-Only Tone Study (00:17:21)

    d. Infinity 556K Hazard Maps in Silencer Hazard Map Brief 8.1.37 (00:22:05)

    e. Performance Comparisons and Overall thoughts (00:26:59)

Episode 312 - Strategic Sciences MFMD + SDX .308 Testing and Tuna Cans Tech (30-JUN-2026)

Today’s Topics:

  1. Sound Signature Review 6.229 – Tuna Cans 5.56 XL and WRMFZY 5.56 on the 14.5-in M4. Two silencers from the new breed of economical manufacturing that is occurring in the industry. Well-understood traditional and conventional baffle designs. How does varying length and volumetric expansion vary performance, if at all? Deep dive into last week’s multi-silencer case study report. (00:08:15)

    a. Intro and recap (00:09:54)

    b. Tuna Cans overview (00:15:11)

    c. Tuna Cans silencer design (00:23:33)

    d. Hazard Map Brief 8.1.26 (00:31:31)

    e. System performance (00:35:29)

    f. Overall thoughts (00:55:44)

  2. Sound Signature Review 6.230 – Strategic Sciences MFMD + SDX on 20-in .308 bolt-action. One of the most interesting silencer systems we have evaluated in the research, to date. The multifunction muzzle device, like all silencers, suppresses recoil, flash, and blast. How does the MFMD compare with other things on the market? Are reflex designs making a comeback? Introductory discussion for this very high performance system. (00:58:17)
