Quote HistoryQuoted: For those with a Sierra 5 on backorder at SS, how long have you been waiting? Considering placing an order through SS but may go elsewhere if I can find one in stock. Since the day they came out and were supposedly in stock. My FFL dealer and I both ordered one same day, still waiting. May 27 IIRC, 76 days in and haven't even been able to start my form 4 yet. |

Not all my local SOTs have them in yet, but 2 out of the 3 do. The one shop that doesn't have them in yet is Utahs largest SS dealer which I find odd. Of the two that do, its a smallish shop and the other is a retail chain (Als). I guess Mr. Magoo didn't make enough their first go around.
Deadair had a rep in the small shop that had the sierra 5 in. I told him I was seeing a lot more keymo sierra's than I was the xenos. It sounded like they prioritized the keymos but he never actually confirmed it. He did confirm they aren't slowing down on making them so they'll be here when they get here. Nothing like waiting on top of a shit load of more waiting! The chain store had a xeno sierra, which is the only one I've seen in the flesh. Its also the sierra I'm after, although I'd much rather support my local shops that aren't chains. |

That being said, my home-based crack dealer (errr, FFL) in Riverton is usually my go-to. I think if you find what you want and the price is decent, get the wait started! (Or maybe I’m 53 weeks in on a form 4 and feeling disenchanted with NFA stuff right now) |

Quote HistoryQuoted: $800 is a bargain? He did begin by explaining his appreciation for his Surefire, so for something that presumably competes with that (and now 3 major reviewers suggest that it does) and includes a muzzle device, it is a bit less expensive for that class of suppressor especially at current "street/internet price." |

I am interested in hearing how well this can performs on DI AR-15s (10.3-16" barrels) in terms of gas blow back.
The biggest advantage I see for this can over Surefire or Hux-WRX, is quite simply the Keymo and Xeno mounting systems. I have a SCAR-16S with a 14" barrel pinned and welded to a SCAR 16 specific Keymo flash hider. I have a Deadair Sandman K in jail, which will be used on that rifle and a few of my AKs. I am interested to see if it would be worth buying a Sierra 5. I have no intent of running it on a 4.5" barrel full auto   . Likewise, I am not worried about a bad batch of cans. Dead Air will fix the problem.

I have Xeno on most of my guns which did play into my decision making process. I was also considering the Flow 5.56K but didn't want to buy ANOTHER set of muzzle devices. One of the reviews I saw stated the Sierra 5 was not too bad for blowback. I was also concerned about that but I figured I have AGB and ABCG's so I'll make do. |

I got to shoot a Sierra 5 this past weekend during a Dead Air demo at West Coast Armory in Everett, WA.
Thank You to WCAN and DA for making the event happen, for all the work that went into it, and for providing all the cans and hosts and ammo. I have no relationship with WCAN nor DA, apart from having shot at WCAN a few times, having gone there to a Surefire demo many years ago, and owing a Nomad. My experience with cans is primarily on 5.56mm with barrels <16” and I own and use a variety of cans and I tune these guns to optimize them for suppressed use. Having said the above, the S5 was mounted with a Xeno on a 16” carbine, which was not optimized. Not sure what the ammo was. I was part of a group of 3 shooters and observed closely as the other two shooters shot this combo and I made a video showing from the ejection port forward. I noticed no FRP. I did notice first round flash for the other two shooters. It was about 4” long and the diameter of a pencil. There was no flash from subsequent shots. I did not notice any flash from behind the gun when I shot. Ejection pattern (FWIW) was about 2:00. |

I experienced no gasface whatsoever.
One of the other shooters (hadn’t shot with a can previously) noticed a little bit of gas but he didn’t know about this phenomena, so it was a totally new experience for him. Caveat, round count was very limited (2 rounds per shooter), but the ammo was provided, so I get that they had to keep their costs down when providing ammo to an uncertain # of people. The other shooter shot about 20 rounds, rapidly. He noticed some gas but nothing oppressive. Some indoor ranges have a very noticeable ventilation system, with airflow being very noticeable and it directs gas away from you. I did not notice this in the bay that were were using and this perhaps was a factor. The S5 did a good job with tone and sound levels. Now while this was the only 555 can/host, there was a wide variety of other cans/hosts, to include .300 blk sub, .308 super and sub, 44 special, .45 acp, 9mm, and .22. While this was a pretty minimal use of the S5, I came away from the experience with only positive impressions. IMO it does a good job for a K can and its on my short list. |

Well I guess I may order one through my local dealer then. I'll probably sell my KAC QDC can to fund this. It is over gassed and is currently beating the hell out of my RD SAM-5 despite the adjustable gas block (carrier and rear trunion deformation). Not sure why RD didn't call me that it was an over gassed can like I asked.....I would have had them install a Surefire FH. Darn it. Need to change the pin and weld.

2 rounds per firearm per shooter. That’s right, 2 cartridges.
You could not provide your own ammo. I chose to not buy ammo from the range to shoot more ammo. |

That's fair, I never paid much attention to meters until Jay started really digging into the Mk18 tests where we get a lot more than a muzzle reading. I'll take your word for the 4db rule, I've heard similar before, and it does seem silly to split hairs with dbs in the context of 5.56. So maybe it wasn't very fair of me to mention "no data." Night shots and/with comparisons to competitors (i.e. Surefire Mini2) would be very cool though. Anyway, thanks for the content. |

I’d like to see an extended review of the Sierra 5 on a 10.3/10.5 or 11.5” AR. This is the platform that a vast majority of 5.56 can owners use. The major online review sources all use much longer platforms and then have very brief coverage with unorthodox short platforms like a 13”/11” bullpup or 8” AR and then say it does well on short platforms cause they’ve tested it.
Yes, we all want cans to use on various platforms, but our cans don’t spend a majority of time on a 16” (talk about unwieldy). I think Silencer Shop sound tested all their 5.56 cans on 16” platforms in their YouTube videos to make the cans they sell sound as quiet as possible. For we actual shooters, our cans are on 10.3/10.5 or 11.5 for a vast majority of the time. The professional reviewers know this…seems like they’re kind of avoiding the standard platform we use. Sorry, but it does… I’m not saying I think the Sierra 5 must sound crappy on a 10.3/10.5 or 11.5 AR platform, but it might sound just acceptable - which would still make it awesome for its size, strength, flash suppression and compatibility. I’d still want one. Glad for the amateurs posting the standard platform content. Just don’t get why the major player reviewers are avoiding it… |

Quote HistoryQuoted: I went ahead and placed an order too. I figured if there is a problem DA will take care of us as customers. I have Xeno on most of my guns which did play into my decision making process. I was also considering the Flow 5.56K but didn't want to buy ANOTHER set of muzzle devices. One of the reviews I saw stated the Sierra 5 was not too bad for blowback. I was also concerned about that but I figured I have AGB and ABCG's so I'll make do. Quote HistoryQuoted: Quoted: I am interested in hearing how well this can performs on DI AR-15s (10.3-16" barrels) in terms of gas blow back. The biggest advantage I see for this can over Surefire or Hux-WRX, is quite simply the Keymo and Xeno mounting systems. I have a SCAR-16S with a 14" barrel pinned and welded to a SCAR 16 specific Keymo flash hider. I have a Deadair Sandman K in jail, which will be used on that rifle and a few of my AKs. I am interested to see if it would be worth buying a Sierra 5. I have no intent of running it on a 4.5" barrel full auto . Likewise, I am not worried about a bad batch of cans. Dead Air will fix the problem.I went ahead and placed an order too. I figured if there is a problem DA will take care of us as customers.

I have about 200 rounds or so through my S5 now. About half on a 16" and half on a 12.5". I thought the blow back was very mild. If 556 was cheaper  I could shoot this suppressor all day no problem. On my 16" I run a 35° offset RMR which puts my face in line with the ejection port and it was not an issue. 12.5 felt the same, for me the blowback is a non issue. |

Anyone have a Turbo K and Sierra 5 they can mock up with a Griffin Plan A mount? I will be running a minimalist flash hider so there should be enough clearance. Any confirmed weight with the Plan A on each would be much appreciated!
Seems like the Sierra is a whole lot of improvement over the Turbo K at the cost of ~2oz and ~0.25" |

Went to the indoor range to sight in a handgun and someone was shooting their Sierra 5, I'm pretty much sold now. I was surprised at how good it sounded. It was noticeably quieter than my Resonator K indoors. Will definitely order one by the end of the month.

One of my local shops had two Keymo versions, so I bought one. Everything I’m seeing so far makes this can look very promising on the fronts that matter to me.

i went over to the pew science ranking page just now and i was surprised to see no 556 dead air data. does anyone know if Jay has a sierra 5 in hand to test? pappas said the S5 would meter a few dB quieter than a sandman S.
Quote HistoryQuoted: Seems like the Sierra is a whole lot of improvement over the Turbo K at the cost of ~2oz and ~0.25" i bought a S5 today. it was a keymo because i couldnt find a xeno; i took the mount off and i couldnt believe how small/short this can is. for comparison, my rex MG7 224 is 5.6" and the S5 is 4.87" (with no mount). im sure the direct thread guys will love this. i was also impressed with how much stuff this came with out of the box. for $800 i got a can, a keymo mount, a 3 prong flash hider, a muzzle shim kit, and two spanner wrenches. the xeno mount version is even cheaper. ill have to sell off the keymo stuff, but that wont be too hard. i am almost positive i complained way earlier in this thread how long dead air took to release this, but damn they seemed to have done it again. i hope they get a bunch more out soon to the masses, i know some have had a hard time finding em (myself included). |

Ordered from silencer shop May 31, day they came out. 125 days later and nothing. Just spoke to my dealer and we are cancelling our orders for two of them and will find them elsewhere.

How do these sound compared the old school specwar and specwar K?
Debating if it's worth swapping to these for my course rifle but man I love the specwars. |
