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)

Today’s Topic:

1. Sound Signature Review 6.239 – Liberty Precision Machine Torch 762 on the 10.3-in 5.56 MK18. It’s been a while since we’ve evaluated a .30 caliber silencer on 5.56. Is that because over-bore suppression is hard? Maybe. But maybe not if you’re the Torch 762. Let’s take a look at this highly optimized advanced hybrid design in this introduction to today’s report. (00:07:05)

a. Intro and why, historically, .30 caliber silencers on 5.56? (00:09:30)

b. When did it get better, if at all? (00:24:45)

c. What’s the Torch 762? (00:36:13)

d. What about mount performance? Other calibers / cartridges? (00:41:47)
