AEAC Video - Brocock Bantam Sniper HP .22 - vlog19

Looks like a super sweet rig. What does the inside of the shroud look like? I wonder how much the shroud reduces the noise by itself?

An air diverter at the muzzle directs a good portion of the air back into the completely functional oversized shroud.

^What Michael said. And don't underestimate the value of a good shroud, even if you are installing an additional moderator. I haven't satisfactorily quantified the improvement from the shroud, but I can tell you it is quite significant. I hope that helps. If you want some rough numbers PM me and I will see what sound meter data I can scrape together. :)
