New video out answering the question how loud is .22LR through the SilencerCo Octane Series. For this test we used the Octane 9mm, Octane 45, and the Octane 45K. As a bonus we also took the 9mm endcap and used it on the 45 to see if there was a difference.

Saw, that video. I went straight to yours and silencerco's web site to see if the 9mm end caps were for sale and no luck yet.

summary:

CAN	muzzle dB	@ear dB
Oct-9	121	122
Oct-45	120	131
Oct-45K	123	125
Oct-45:9EndCap	117	129
Oct-45K:9EndCap	119	125

the @ear numbers seem strange to me, particularly for the 45 series.
Oct-45 is quieter than the Oct-9 at the muzzle but it's louder at the ear? by 9dB?
45K gets quieter at the muzzle with the 9 end cap but stays the same at the ear?

personally i'd like to see the sound spectrogram at the peak; or even better, an animation over time.
also, i think it would help to see a graph of the loudness over more shots (10, 15, 20?). i feel that the industry's too hung up on single number shot averages. a graph of 10 shots would show the first-shot-pop and also show whether the can gets progressively louder, as would be the case with sealed designs.

thanks for the video. i've noticed the host has changed numerous times during the four year time span. :mrgreen:

So the reason for 5 shots is that if you do more shoots the FRP gets lost in the average. You can tell how good a silencer is by how close the shots are to each other. Also 10 shots on a video would get boring.

Jeremy, is there a list to get on for the octane 45-- 9mm end caps- if like one as well.

There is no guarantee that they will come out we are just testing the waters. I'll keep you updated if it progresses.

I asked 2mo ago if I could run a 9 endcap on mine and was told no.

where can I buy this and what discount are you offering members here? Free shipping at least I hope

 

[Mark McWillis]

Makes ya wonder what they'd do with a .22 end cap, doesn't it.......

I never said that they are coming out. We just tested it to see what the response was and how it performed. We always have free shipping on our site FYI.

Until an ATF letter is produced allowing this it's still a no-no. As for where to buy, no one is actually offering it....yet.

 

[roaddog359]

They are doing it, I don't think they would try different end caps if they thought it was illegal. Anyway does anyone know if there is a ruling to cover this question?

 

[Jeremy M.]

It is not legal to have both end caps unless you have both silencers. This was more of a test than anything else and there is no official word as to if or when they will be released.

 

[Performify]

Yeah I'd love to get a 9mm endcap for my Octane 45. And a 22LR one

 

[TheYoungConnoisseur]

Then why aren't the other end caps ilegal? Lots of people have 4 different theaded ends. Talk about retarded

 

[TheCameraMan79]

So when you did the test with the Saker 7.62 with the Saker 5.56 end cap if you didn't own both suppressors you wouldn't be able to do that? I knew you couldn't have spare baffles laying around but I was unaware you couldn't have the different end caps.

Unless things have changed very recently end caps are silencer parts and you cannot have extras. But it's a different situation with the Saker because of the maad brake ( www.store.silencerco.com/products/maad-brake ). The brake takes the different end caps that also just happen fit on the saker. So they aren't considered a silencer part because they are actually parts for the MAAD brake which isn't an NFA item.

100% correct

 

[micah7488]

I was reading your industry thread over on arf, and saw that y'all said with new suppressor purchases one could also get the 9mm endcap. Would I have to purchase the endcap before my form 4 gets back from the ATF or could I purchase the end cap when I go pick up my Octane45HD from the store in Austin?

I believe you all sent my form 4 the week of the 16th in Feb. and my check was cashed on the 23rd.

Not retarded - If the guts of the suppressor can be removed from the tube (you could change the caliber of the suppressor guts) (most of your pistol) and can remove the endcap as well...there is the problem....and that rub of having 'extra' silencer parts i.e. the endcap(s) ALOT of room here for criminal intent and well getting over of Uncle Sugar and not paying additional tax

Since the rifle suppressors (the guts are welded in place) cannot be removed - but the endcap can - (bonus since you are changing the exit aperture) not the registered caliber of the rifle suppressor....there is no problem

Your head hurt yet? That's ok - go read thru some of the ATF Tech Branch rulings if you wanna make your head really hurt
