Here is the first independent test of one of our cans. It is the first production model 556-45 and was metered by a manufacturer in Canada.

Rifle: 14.5" M4
Ammo: American Eagle 62gr
Sound Meter: B&K 2209 / 4136 mic
Test Protocol consistent with Mil Std 1474D as described by Phil Dater and Al Paulson. (Silencer History and Performance Vol 1, pg 85)

Raw Data: 140.1, 135.8, 137.0, 135.0, 136.7, 137.2, 136.4, 136.0, 138.3, 136.7

Avg SPL: 136.9 dB (hearing safe is 140 dB)
FRP: +4.3 dB

Thanks for sending it to me, it is a very neat piece. I applaud your willingness to let the data be public. Too many designers won't share real data or try to cover up or obfuscate data that isn't great. You have done a good job with a very short can. For comparison sake I looked up my data on the BR Tuote Reflex Suppressors and yours did virtually the same SPL as those, which are def longer than yours.

What was the dB without the can?
