I'd like to thank Matt at Front Toward Enemy Firearms for setting up the testing, and Bill from NFATalk for sitting for about 5 hours while we metered suppressors yesterday. There were a couple other INGO members there for short bursts, and it was nice to put names and faces together.
What did we learn? Matt is an awesome host, cooks a great sandwich, and his daughter is a swashbuckling protector of the innocent. Bill really knows his stuff when it comes to all things engineering. And that the Sparrow costs about $100 pe dB reduced over the cost of the Guardian. Yep, head to head the Sparrow metered 3 dB quieter than the Guardian, and costs $300 more. Simple math. We'll give up the 3 dB. You keep the $300 change.
The B metered incredibly. At just 3.75 inches long, it didn't win the quietest can of the day award. But it was impressive. While waiting for Bill to crunch and release the numbers, it's safe to say it metered competitively to the Yankee Hill Mite. At over 1.5 inches shorter, that's a pretty tall (or short, as it were) order.
Same with our Guardian 9 prototype. It metered well within hearing safe range dry, and when wet was quieter than the Yankee Hill Cobra 9. When you consider that it's still a prototype, is 6 inches long, weights 4 ounces, fits under your current sights at a diameter of 1.085 inches, and can play hide and seek INSIDE the Cobra Tube, I think that's a pretty good accomplishment.
Again, thanks to Matt and Bill.
