I’m looking for an upper for my SBR lower and suppressor. I’d prefer something 12.5” or shorter. It will be shot suppressed 90% of the time most likely.
What would you buy and why? |

Take it to suppressed 100% of the time and get triarch's 11.5 suppressed only

I believe BA has the same spec barrel (not the identical barrel) and I’ve heard of them and used their barrels. Always willing to learn. |

Centurion will cut you a 16" to 12.5" with a mid length gas system and port sized for a dedicated suppressor host. Accurate and well balanced barrel.
|
|
What max caliber is your suppressor rated for?
I'd be tempted to do a super quiet 22lr or 9mm build, or if you just want to tone down the blast then 762x39 |

View Quote They put more emphasis on gas port sizing than a lot of other manufacturers. Like you said there are other companies doing it, but reviews have been pretty good on the triarch barrels and handguards. I have no personal experience, but If I wanted a complete upper to run suppressed only, I'd give them a try. Their prices aren't that high either. I'm planning on doing a 12.5 build using their barrel and AGB at some point, but I don't think I'd want suppressed only personally. |

What's the purpose of this weapon? I really like my 12.5" in 6.8 SPC a lot. Great power for hunting. If I was looking for plinking I'd go 12.5" 5.56 no doubt.
I also have a very short 8" barrel 300blk that's light and handy. Extremely quiet with subs. Supers are still good enough for hunting, but not as good as the 6.8 SPC. For home defense if I was worried about over penetration I'd go 5.56mm. Or 300blk would be the quietest indoors. Or 6.8 for max power factor. |
|
If I get a suppressed only barrel, I hope they don’t ask me what gas port size. I have no clue.
I’d only use one or two type of ammo. Like M193 or M855 for simplicity. |
|
geissele super duty 11.5" upper is the answer. worth the wait for them to come back in stock

Thoughts on triarc’s 10.5 suppressed only barrel?
With a griffin GP5 it’ll be 16 inches. If I chose to pin weld. I’m not asking if pin welding a suppressor is a good or bad idea. |

BCM. Thousands of full auto suppressed rounds, still at 1.5 MOA zero issues, and perfectly ported.

Triarc will personally work with you to make sure your suppressed only upper is exactly what you need. They will answer the phone when you call and call you right back if they cant. If you have used parts from other companies you want to build with you can send them in and they will set it all up for you. I'm always trying to brag on Triarc - they seriously hooked me up a year ago when I had issues with a whole rifle build that only had one Triarc part in it... |

I really like my Sig 516 10.5” upper that runs a full time YHM-turbo K.

AndroCorp 10.3 crane spec upper...I have two of these barrels now, but they sell complete uppers too. Perfect size gas port (.070) for suppressed and suppressed use. They use ballistic advantage barrels, which are awesome.

Hodge 12.5, Geissele 11.5, Sionics RGP or ERGP, Centurion 12.5 midlength.

Another thing you're getting with Triarc Systems is one of the absolute best rails on the market.

Lefty, and I’ve only shot a few rounds through it without a can. No failures. This is the way. |

Now in terms of a non-supressed or partially suppressed build I would be cautious with Triarc because they port on the small side for sure... but a 100% Suppressed build would reallllly take advantage of those special Track 2.0 barrels they use and the special port sizing. I put a h2 buffer and a tubs flat spring in my KAC CQBR Mod2 and ejects at 2:00 suppressed and locks back PMC .223 un-supressed. I was also having gas to face issues when gun was very clean - pri gasbuster fixed that. Using Surefire mini2 |

Seems like knowing the purpose is a really important question to answer.
8" 300blk 12.5" 6.5 12.5" 6.8 One of those three depending on use. |

Building the wife a 100% suppressed gun soon. Was just going to get a criterion barrel like usual but I'm open to new options. I put another 800rds through my mod 2 cqb kac this weekend at a training class and had no issues except one stovepipe, I think it was the magazines fault but I'm not sure. The rifle was dirty and dry at that point so I couldn't really tell. Also the possibility that I knocked the casing back into the ejection port since I was shooting support side. |

Thanks for the wealth of information, it really seems that Triarc has the smallest available gas port that I can find, I just wish they were cheaper!
That sionics ERGP also looks like it might be the ticket. I need to contact them and see what the gas port sizing is. |

A member above posted it is “0.50” but I don’t know that as first hand knowledge. I plan on emailing them today though.

Unfortunately MicroMOA closed. I have a 12.5 upper from them with the Govnah. The Govnah has a plate with 3 holes of your choice. Mine is .055 suppressed, .073 not, .082 dirty and / or weak ammo. Mid Gas
My other SBR AR is a Adams Arms piston 11.5 upper. The gas adjust has off, normal, suppressed which is suppose to be 1/2 normal. It runs great, have done several classes with a Specwar 556K. On suppressed setting without a can it's a single shot. With the gas off, obviously it's a bolt action but noticeably quieter. |

The barrel is also heavy AF like a freaking SOCOM profile. I sold it almost immediately. I ended up going with the Crane spec (0.07) spec Andro 10.3 barrel (it's a ballistic advantage barrel that's to their spec and rebranded...very smooth shooting suppressed and unsuppressed) |

It looks like there is an overwhelming amount of people suggesting the suppressed only Triarc uppers/barrels.
What handguard and or barrel lengths are you all running? |
