Osprey Defense Scuba Test: Questionable Methods

Okay, if you’ve read some of my other posts, you’ll know that I’m not the biggest fan of piston/op-rod conversions. But hey, if you’ve got a suppressed full auto rifle, you’re getting closer to the zone of performance where the benefits outweigh the drawbacks.

Some folks may have seen the HK416 OTB test, where it outperforms the Colt M4 – and while that video may also have issues, they aren’t as glaring as this one. The whole point of this test is to show that the barrel can be full of water – as the shooter comes out of the water – and fired with water in the barrel without blowing up. A standard AR-15 can be sealed at the muzzle or allowed to drain for a few seconds, and it will pass this test just fine. Again, if the barrel isn’t full of water, the test is meaningless.

In this Osprey video, some disheveled guy in a black T shirt says some stuff, then a heroic scuba diver emerges from a mud puddle and engages an imaginary target. I know he was only under for a few seconds, but if you’re trying to demonstrate to divers how well your product works underwater, you might want your demonstration diver to properly put on his equipment, to include attaching his low pressure inflator hose (the hose coming over his left shoulder). Otherwise, it just looks very unprofessional to even the most inexperienced divers, such as myself.

First, we’re allowed to see the guy go underwater. Now, in the HK test, the protocol calls for the rifle to be submerged until there aren’t any more bubbles. Here’s the front end of the silencer as it goes underwater. Click on the photos for a larger image.

It’s hard for me to say definitively that there aren’t any bubbles. It’s possible that tiny bubbles are coming out. I’m not seeing any, though. And frankly, with the weapon being submerged at that angle, it’s unlikely that a lot of water would get in there (and it’s likely that, considering the amount of time at which he he holds the weapon at an up angle as he comes out of the water, any remaining water would drain from the barrel). Here is a screenshot just as that silencer goes underwater.

The lack of bubbles alone isn’t definitive enough, but what happens after he starts shooting throws up a huge red flag for me.

See that silver thing hanging off the end of the suppressor? If you watch the video, you can see it flapping as the rifle is fired. That looks suspiciously like some sort of object used to plug the muzzle to me. If there’s some sort of innocent explanation, I’m all ears. At this point, though, the lack of bubbles in conjunction with the apparently plugged barrel makes me very suspicious of their claims.

Edit: An AR15.com poster whom I know to be honest reports that he is a friend of the diver in the video, and the end of the suppressor was covered in duct tape. Thus, I feel very confident saying that this test was a sham, and the company should be ashamed for trying to pull the wool over the eyes of potential buyers, who will hopefully find another solution.

    I like the screen caps, good work and keep exposing the frauds. How about a BS or Scammers section to keep people from buying junk? you accept no advertising (currently anyway) so you are in no position to have to be PC about a product

    Duh, I see you have a “Lies, Errors and Omissions” page. Nevermind.

    Duct tape huh? Sneaky bastards! I just thought that the silencer had blown a piece of baffle out or something.

    This thing initially look intriguing but there are too many inconsistencies. The sand test, the scuba test… I have only seen a couple of those that impressed me, the 416 v/s the m4 and the acr tests.
