I was watching a Garand Thumb video today about his SOLGW 13.7” pin & weld AR. It got me wanting one! The more I’ve been thinking about it though, I’m wondering what combo of barrel length and muzzle device is best for getting an OAL of 16/16.1”. What say y’all? (His was a 13.7” barrel with SOLGW NOX)
ETA: I guess I should have said up front - I already have 3 pistols and 2 SBRs. Just wanting to do something different this time around. The goal is to have a 16” combo and I’m asking for advice on which length barrel and which muzzle device to use to accomplish that. ETA2: I don’t plan on suppressing this gun so I don’t have to use a specific mount. ETA3: Here's the video that started this  13.7" Do it all AR15 (Sons of Liberty Gun works AR15) |

Ess
Bee Arr  Seriously, I love my 13.7, but if legal rifle length is the goal, 14.5 is what I would do. I have no 16" barrels, all of my non SBRs are 14.5s, and I love 'em. Since you have to get to 16, using a super long FH gains you nothing. My 13.7 Infidel has an AAC suppressor mount on it |

Pin and weld is whack.
Use a brace or SBR. |

Voted 14.5", but why not just build a pistol? Braces nowadays are pretty damned slick.

imo if the point of the build is to go as short as possible while meeting 16 inches, you want to shift the bulk of the weight (read: handguard and barrel) back and 13.7 is the best way to accomplish that
it also looks really slick when paired with the numerous 13 inch handguards on the market, you can get your muzzle device (or suppressor) right up near the edge of the handguard ala MK18 13.7 + Nox is a fantastic combo, only reason I'd go longer is if cloning (ie: Block II) or if the company didn't offer 13.7 exactly (ie: Triarc uses 13.9) |

The only reason to go shorter is if you need a really long muzzle device for your suppressor, and pinning it is going to put you way over 16".
Buying a super long muzzle device just so you can get your barrel to 16" is kind of pointless. |

Not sure why you chop off an inch of barrel length(Velo) and run a long MD and end up with same gun handling -the velocity? Honestly the best would be a 14.8-15"ish barrel with a short GA minimalist to get to 16". That being said, I'd just run a pistol lower with a SBA3 or SBR it. I hate having my MD pinned in place, but I'm always changing things around. |

Other than that I don’t get the appeal. |

13.7 exists because that's the length needed to pair it with the best FH available (249F) to reach just over 16".

I agree with the 16” for better velocity, but I do really like my Spikes 14.5” Optimal barrel with a Manimal flash hider as it let’s me remove the gas block to change the configuration if I want to, without removing the flash hider.

People must not realize that if you are already using a long muzzle device that fits your suppressor, going to 13.7 will set your suppressor back that much further.

Yep, surprised most haven't picked up on that. Currently building a 13.7 SOLGW with the nox and Triloc rail from TRIARC, just waiting for back ordered parts. While I haven't shot a 13.7 build, the advantages seem obvious. Better weight distribution, suppressor sits further in and its still considered a rifle so no dealing with braces. |

I think 12.5 with suppressor is ideal for me, but finding something that comes close to that without a stamp would be awesome. |

I was going nuts trying to make this decision recently for a current build and ended up with a 14.5" with Surefire Warcomp under a Geissele MK14. I'm in love. When I weighed all the differences the .5" OAL didn't make sense just for cooler 13.9". I know it's not a huge loss in velocity but a loss is a loss.

Man, this is a tough choice! There are at least twice as many votes for the 14.5" over the 13.7" but I just can't shake the idea of wanting a 13.7"!
I don't plan on suppressing it so I don't need a MD that accepts one. I found a "no mount" NOX that I could put on it, but OOS. I'm still trying to decide! |

The length of KeyMo offsets any of that. I need to line up my buddies 13.7" with a Sandman K vs my 14.5" w/ an omega and Plan A again. Should have took pictures, but it's negligible either way and he's down an extra inch of barrel length. |

The only reason to go 13.7 is if your going to suppress it and don’t want to SBR it. It will set the suppressor back further and you can put a normal stock it.
