I purchased the shroud for my Condor from Airhog. 85% seems right on target for mine. I can plink all day without bothering anyone. Also drilling a few holes in the two barrel bushings will increase air flow and decrease the sound even more. I've had my Condor three years this month and literally wore it out. After a tune up (professionally done by Talon Tunes) and a few upgrades I do not regret the two grand... plus some I've spent on my gun. #$% I gotta sent a pic next time. lol.
