Looking to go with a new setup, options im considering are all from dead air and are the

Sierra 5
CT5P
Lazarus 6

I’m going with xeno and they will be run on 11.5 5.56 AR and 16” 5.56 AR

Looking for flash reduction and not necessarily the quietest sound, and low back pressure

I believe that I've heard the Dead Air guys mention the CT5P is slightly better at flash reduction then the lazurus, while being decent on backpressure still.
I have both the sierra 5, and laz 6. The sierra 5 is a bit punchy on a shorter host vs the lazurus. I haven't gotten the chance to shoot both at night though to comment on flash reduction with them.

If the hub capability isn't important I'd probably go with the CT5P

If you're set on Xeno then I'd go with the CT5P. Lazarus give you hub mounting options, but weighs a bit more.

Sierra came out in 2022 and was the last of the DA welded baffle designs. The 3D print/ low back pressure revolution started in 2023. Lazarus is 1st gen 3D print, CT5P is maybe v1.2, lighter but locks you into Xeno mount. If you know you want Xeno then I might pick CT5P over Lazarus, but mostly they are the same design.

Is there any reason why youre limiting yourself to dead air?

The only thing id buy from them this day in age is a mask or a nomad OTB. Everything else is dated or not good enough at the price they demand.

If low back pressure is a priority (you mentioned it), please don’t consider the Sierra 5. I had two of them and they are very high back pressure.

I have a Laz 6 and its a tank of a can with no barrel length restrictions. I really like mine and have no experience with the other cans mentioned. My only other reference can is a Hux 556 and it has way less flash.

@LuvThmGuns

The hux had much less flash than the laz6?

Sierra 5, Sandman S, and mask checking in here.

the Sierra 5 is not low back pressure, but it is short and sounds great. I'd go Lazarus 6 or ctp5 of the choices you mentioned.

No the hux has way more flash and spark. Sometimes my brain outruns my fingers when I type.  

I really like the Xeno mount with the laz 6. No timing issues and it has been solid. I run my laz 6 on my Mk18 clone and its been really solid.

Why only dead air?
So many better options.

Ahh, thanks for the reply, you saved me a big oops! Flash is my primary attribute

I have all three as well and agree on the Sierra5. I like it on my 10.5", but it is a bit punchy. But, I haven't had any issues with it, either.

^This....anything else is a better option than dead air.

FireTeam 556, Rhodie 6, or Rhodie 6K.

Stupid quiet; truly hearing comfortable even on 10" barrel.

Low backpressure, and that's coming from a lefty.
