DA Sierra 5 Experiences

[w3453l]

I’m about to buy my first suppressor that will be going on an 11.5” FBI Spec barrel with 0.069 gas port. I’ve been researching and reading between here and other forums trying to pick what “the best” 5.56 suppressor would be.

I know 5.56 SBR won’t be hearing safe no matter what. I’m mostly trying to just take the edge off of the concussion of a short barrel.

I have a PRI Gas Buster CH on the upper already, and as far as I know that’s all I can do about minimizing gas to face (im not interested in adjustable gas blocks).

I’ve narrowed my choices to DA Sierra 5 or Sandman.

For a suppressor staying on a 5.56 AR, is there any benefit to getting the larger Sandman?

The only other thing I’m mainly concerned with is backpressure, but I haven’t seen any negative things said about the Sierra 5.

Does anyone have any input/reasons to avoid the Sierra 5?

Some final details about the host AR:

-11.5” Centurion w/ FBI spec barrel (mine has 0.069 gas port; I know they were recently changed)
-Lower receiver has A5H2 buffer (I can move up to an H3 if need be)
-I have an FCD 6315XE (Xeno mount) already installed on the barrel, but if there’s good enough reason I don’t mind switching to something else before I make a purchase.

You can't go wrong with Dead Air. Both are nice cans. If you're sure you're ok with a dedicated 5.56 can then there's no reason not to get the Sierra 5.

No experience with the Sierra 5 yet. No reason to ASSume it won’t serve you well, though. If you change your mind and go for a Sandman, do the S, not the K.

I think you made a good choice in mounts.

Is this gun ever getting shot unsuppressed, other than initial keyhole checks?

Thanks. The Sandman S was the only other one I was considering.

The plan is that the gun will be shot only suppressed, I can't think of any scenarios where I would pull the suppressor off to shoot without. But that being said, I try to never say never.

The Sierra should be a better choice than the Sandman on a 556.

It's shorter, lighter and slightly quieter according to Dead Air.

For a dedicated suppressed setup, look into an EZTUNE gas tube to reduce the gas rather than increasing the buffer weight.

Thanks, I'll look into it.

So far, unsuppressed with A5H2, I was getting a few failure to lock back on empty magazine. This was with Wolf Gold; it was recent production, so I don't know if it's lower pressure than it used to be. The gun shot "soft", I know that's very subjective and not a good data point, but I think the gas drive should be good once I get a suppressor on it.

I don't remember the temperature, but I want to say it was low 40's.

That said I bought two stamps, and will hopefully get to the store to put the suppressors on layaway.

I'm decided on the Sierra 5 and will also grab a mask for .22 lr.

Not sure how much real world average joe feedback you're going to get about the Sierra5. Even if someone ordered one when it first appeared they wouldn't have it for half a year yet or more. Only ones who have them are reviewers.

I have a Sandman S sitting on a BCM 11.5 and it has served me well with a few thousand rounds through it so far. I would imagine the Sierra5 being just as good, maybe better. I have a Geissele charging handle which is supposed to alleviate some gas to the face but after a mag or two in quick succession you feel it for sure. For some reason it was way worse when running that can on my 18" Noveske, maybe because I was in prone, no idea, but 10 rounds in I started to feel it.

I have a pair of Sionics 11.5 reduced gas port barreled uppers mounted on lowers with A5H2 buffers, and I will say that I've never had a single issue locking back unsuppressed. Even with weak Russian ammo. If you're having issues with lock back with Wolf Gold on a 0.069 gas port barrel, I'd make sure that your gas block is properly installed, and then I'd try a different BCG to make sure the one you're using isn't out of spec, and potentially leaking gas.

I have a Sierra 5 and Mask along with a Wolfman still in ATF jail since July. I need to order a couple 6315XE's to accommodate my DDM4V5 and a 12.5" upper with a BRT barrel. We'll see how they deal with the additional backpressure. For some reason, DA doesn't make a Xeno adapter for the Wolfman from what I understand, so I have to go with Keymo on that one.

Yes they do, and they are in stock:
