And here I am.
I got one of the first NH AAC's that came out to the non connected public with every intent on getting the Ti-Rant from AAC to put on it.
Then I went to SHOT and talked to the people from SilencerCo. Those people are PASSIONATE about what they do and the Osprey is something that AAC started, but SilencerCo finished with simplicity and excellence.
Originally AAC was going to produce a lower than barrel axis, higher volume suppressor called The Black Box. You can google it. It was WELL reviewed and it was supposed to revolutionize the suppressor world on the pistol front.
The problem was AAC could not make one suppressor that would index properly on every threaded pistol. They never wanted to, or never wanted to pursue the fix, to release this fix and Silencerco basically just waited.
A couple of years ago they either bought, or acquired, the patent and came up with a really cool index matching ring with a throw lever that allows the suppressor can to spin on the ring. By doing this, the suppressor can be indexed to any pistol that is threaded on the production planet. It's a brilliant design, and fairly simple, but why AAC never pursued it is not known to me.
As for the Osprey itself, it has about 30% more volume below the barrel than any other round suppressor, including the Ti-Rant. If you get creative and fill the baffles with mineral oil, or vaseline as it turns out as an "industry secret" the suppressor makes the .45 caliber round quiet enough to shoot inside without hearing protection.
In the dry application, in a civilian environment, the Osprey makes my NH sound like a nail gun or similar device being fired a house or two away. It totally camouflages the natural sound of the weapon and has thus far attracted no attention from anyone who wasn't paying attention.
In a wet application, and while Vaseline is an industry secret, if you don't have a good solvent to clean it up with it is MESSY.
There is definitely ballistic spatter of the round going through the baffles and taking some of the Vaseline with it, but it adds significantly to the dampening of the sound. I would say, maybe, an additional 20% of noise reduction - but I have no actual noise numbers to verify that figure.
Because of the construction of the Osprey, the index matching ring can be removed and the baffle can be placed entirely in my cleaning tank. The threads are removed completely so there is ZERO chance of damaging the fastening of the suppressor to the weapon. Bonus.
Should the can itself ever be damaged due to dropping, run over by a truck, whatever
there is a very cool additional feature.
The baffles and the can, removed from the index ring, can be sent back without going through an FFL. The index matching ring is the only part that is FFL compliant, so the rest of the "suppressor body" is nothing more than a standard housing. While I highly doubt ever having to take advantage of this feature, it's nice to know I would never have to go through an FFL and pay the transfer fees.
I looked long and hard at both the Ti-Rant and the Osprey. After talking to both companies I decided on the Osprey and I have not been disappointed. Everyone that has shot it has said the same thing "I have got to get me one of these!"
