Have any vids of suppressors in action? Post em up.

Here is one that compares quite a few side by side. The FRP (First round Pop) is noticeable / audible in this vid.

Great video... Nice selection of suppressors and handguns...

Man, that's a lot of suppressors!

Just a point of question... His firing line is 180 degress... behind him.
All his firearms are pointing to the front of the house where everyone lives. He handles them to pick them up (obviously fully loaded) and then proceeds muzzle sweep his legs and then shoots 180 degress behind him.

Just to make it easy... why not just have the guns pointed to where he plans on shooting. Pick up and start shooting no sweeping himself or anyone else or having the muzzles pointed in any way towards loved ones?

Come on really?

I know he maintains good trigger... but even the best of us have had "things happen" so long as the muzzle is pointed in a safe direction... no harm...

Great vids!

What causes "first round pop"? Why is it louder (sometimes?) than subsequent rounds?

The oxygen in the can that gets super heated and compressed.

That's why wet cans are quieter, the water displaces most of the oxygen.

After the first round, there is still oxygen in the can of course, but there is also soot, smoke and other vapors.

Our recent Checkmate II sound test:


Our current M4-SD- the M4-SD II for the pre-order is an updated model.


Our Spartan II, and M4-SD thread mount version (we have some of the short cans but have never sold one as they are more blast suppressor than anything else).


A fun video of an L34A1 in Iraq- the operating spring on this gun was probably weak (causing reliability issues) and I fired the last round or burst into the dirt for sound.


Again for fun- My brother in Iraq with an MP5-SD3


Discontinued Operator .45 next to KAC OHG- both fired wet.


Another Operator .45 test video


The infamous Bushwacker silencer everyone has fits over. It was a good product- albeit a bit ugly. They are all still running as intended- no issues.
You'll have to forgive my enthusiasm / coming across like an idiot. At this point we weren't prototyping and didn't have a meter, and I was just really excited the product worked as intended- in fact it was the best performing 5.56 suppressor I had used at this point. The Ops 12th is better. At this point in this project I think we had $20,000 invested. We'd made a projected performance claim and I knew Kevin Brittingham and Robert Silvers were going to carve my heart out with a spoon and serve it to me if we didn't fall into our projected range. <which we successfully did.


The old discontinued Scout- these metered ~141DB at the muzzle. I didn't have a meter then and sent one to John at Silencer Research and his initial opinion from firing one at night at his house was they sucked and I got the impression they were crap and began to sell them below cost. Turns out 141 is pretty typical and is actually decent to good performance. I know my body position sucks, but the instructors at Army Sniper school taught me that a few weeks after this video was shot.

And one unsuppressed- just because it demonstrates I don't work for Red jacket. icon_winkle
Range is about 15yds so this is not a std distance / drill

i think the fact that you guys arent making a suppressed rocket launcher with laser sighting with a tazer welded to the frame proves that you're not working for/with red jacket. this is one of the few times i will bad mouth a silencer/gun "company" (and im using that VERY loosely with red jacket) but will never have anything good to say about them, wil and his c#nt of a kid.

welcome to the forum by the way.

Towards the end of that video, they shot a Special Interest Arms .45ACP Enfield conversion . . . it reminded me of this thread:

The Valkyre deslisle is pretty much awesome looking. Faithfully executed for sure. A real collectors item. I don't really agree that the baffle system is "maxim". I think the inventor was the first to use the rods and bent split washers to assemble the baffle system, and it works great for sound, but the history I read didn't suggest the best accuracy in military trials. I read an article somewhere where the accuracy results were surprisingly bad. http://www.scribd.com/doc/41365896/Deat ... ng-DeLisle This mentions the issue, but doesn't go into detail. I shot an L34A1 and it was having poor accuracy also and used the Deslisle style split washers. I had the front sight maxed out for elevation on that gun, and some of the rounds were flying erratic of the rest. I think the silencer could have been slightly miss aligned, but wonder if the baffling was just a poor design for accurate work.

The unit we have is SIA, and it probably isn't as quiet, but it is accurate- shooting ~1.5MOA. We were kind of wanting to be picky with sound even though the sound was like a hammer on steel and not like a gunshot, it was loud. We laser cut a bunch of diffusers that look like cookie stamping dies for those cookie caulk guns. Assembled into a stack, with the baffles up front, the silencer sounded better. I didn't meter it, but it still shot 1.5MOA, and sounds better now. Maybe we'll meter it next time I'm home. I'm sure that's not the best way to baffle it either but the M baffles and spacers that came with the suppressor are pretty far apart and that lets some gas blow by creating that sharp 135DB average. The lasered sheet metal diffusers were just more cost/time effective than seriously getting involved in baffle design for one silencer.


As far as Red jacket, I was talking about their poor shooting for people who work around guns. The show is entertaining, I enjoyed watching it and it probably increases NFA awareness, but where they really got me was the episode where the owner's gunsmith on NATIONAL TELEVISION, tells the owner he needs a depth micrometer to properly headspace a barrel (a big safety issue) and the owner tells him if he can't do it with the tools he has there he needs to pack his things. <really? I have depth mic. I can't say I often use it, but I did QC check some checkmate QD mounts with it a couple weeks ago and it came in handy. If I were the owner, my answer on television would be, "alright well make it happen." I'm sure there are ways to work around not having the appropriate tool (like maybe using shim stock and a round of something like that to check headspace), but TV isn't the right place to be talking about how to work around not having the right tool for a job. I wouldn't want people without the right tools headspacing a gun for me, so why do it for someone else?
