Footnote:
17
Our tests reflect how the suppressors performed on the date they were tested, and results can vary dependent on many factors.
18
Suppressors can perform differently due to date, location, humidity, temperature, barometric pressure, ammo type or lot, as well as other factors.
19
Suppression performance should not be the only factor used when deciding a purchase.
20
In other words, do not use the data provided as the "end-all" to what is best. Only you can decide what product is best for you.
