I have one of the 8.5 from a previous run. awesome barrel that runs perfect with supers and subs using a gemtech quicksand...
the 16 inch 1:7 in 41v50 would be a must have out of this group although the 16 inch pistol blackout is a very interesting combo for keeping things super quiet |

I just recived my 9.5 300 blk barrel from them, receI've 2 days after I ordered. Way to early to cmoment on quality other than it looks good. I'm still collecting all my parts for my build.

Geez, so an 8.5" would only be $106.50 total. Man, I might have to get one, pack it in grease and store it until I'm ready to build my sbr. Crap! There's other stuff I want to buy!

I ordered one yesterday, then thought "hey, there's nothing on that page about whether they have M4 ramps or not!" That makes a difference when it comes to what upper to use... I used the site's "contact us" link and they got back to me in minutes. "All we use is M4 barrel extensions." I'm a happy camper now, and will be happier when the barrel arrives.

Yep. Biggest thing holding me back right now is worry about having to dimple the barrel. I'd like to just do it myself so I don't have to mess with shipping it off and waiting before getting it returned, but at the same time I am apprehensive about trying to drill into a barrel.

You really don't need to dimple the barrel. A lot of set screws will cut into the metal and make their own "dimples". Today as a test (not really, I just completely forgot to remove the set screws) I took a hammer to a tight gas block to remove it. It didn't budge at all. The set screws held up to the hammer beating on it. Most low profile gas blocks go under the handguard, where nothing will ever hit them. |

My 16" barrel came in today and it looks great. Here are some specs:
Contour: 0.725" from muzzle to gas block journal, 0.750 gas block journal just over 1" long, with a distinct shoulder (relieved between journal and shoulder) Gas port 0.125± Passes GO and NO GO gage tests (PTG's gages) with a standard CM bolt. Overall the barrel is clean, no visible burs or other cosmetic issues. The barrel is uniformly black with what I'd call "lathe" finish (i.e. tiny grooves versus high polish). Now, I need to get an upper, a gas block, and a BCG, and I'm set!

The 8.5" barrels are threaded 5/8-24. What would be a good muzzle device for it? They should all be threaded 5/8-24, as that's the standard for 30 caliber muzzles. What muzzle device you use depends on what you're going to do with the barrel. If you know you're going with a specific suppressor, get a device that works as a mount for it. Since I know that eventually I'll be getting a .30 cal can, but at the moment I don't know which one, my 8" upper has a LaRue .308 A2 flash hider on it, as will the 16" barrel I just got. It's a lot easier on the pocket book to buy simple stuff (LaRue's A2 comes with a crush washer and lists for $19 something) and later make a solid decision, than to plan on one thing early on and wind up not having that work out - and have to replace one costly suppressor mount with another. |

My thoughts were, if the gas port is 0.125" and the weapon is overgassed, Rather make a gas adjustment then keep adding buffer weight. Once it's set, don't change it. I've made adjustable GB's from standard so cost isn't a factor. Just a thought... |

That's my thought too. "Overgassed" is really "buffer and spring don't match the gas pressure." Adding weight at the buffer end is easier than changing out a gas block, or tweaking an adjustable block.

Got a 16" 1/7 carbine barrel on the way.
I am really disappointed in my homemade 300/221 barrel I made a few years ago. I can't find a good load that will perform under 2" and it is a 1/10 twist barrel. 168/175 subsonic simply do not group, but lightweight bullets do, down to ~2". |

I'm really (as in really, just started researching parts for my first AR) New to ARs .Would one of the 16" 1/7 barrels mount up to an Aero precision m4e1 upper/handguard? What does it mean that it doesn't have dimples? Would that impair reliability or mounting with an Aero upper (or any upper I guess)? Would I need any other parts to mount the barrel to the upper?

The barrel will work just fine with any of the Aero uppers. The dimples are there to help keep the gas block from moving. Most barrels do not come with them, they are an added bonus or something you can sometimes pay additional for. The only thing you will need to attach the barrel to the Aero M4E1 upper is their proprietary barrel but but the upper should come with it. If you do not already have the gas block or gas tube, you will need that as well. If you do not have those two items, get them from KAK to save on shipping and take advantage of the 10% discount code plus their gas tubes are nitride treated. |

Ok the gas block question is throwing me for a loop. How do I know if the handquards from Aero for their midlength upper will fit the KAK glass block with picatinny rail? Do the handguards cover it over or do i need to make sure the handguard length is the right length to butt up against the block? I noticed on some ARs there is more barrel sticking out in fromt of the handguards than others, I liked the way the Aero Precision midlength looked with that amount of barrel showing. KAK also has a low prifile gas block without the rail, does that one get covered up by the handguards?

The KAK low pro gas block will be covered by the barrel.
I assume you want the FDE color? If you do, for an additional $10, you could get the FDE Aero barreled upper from Schuyler and the Freedom FDE Aero lower. All you would need then would be a lower parts kit, buffer tube kit, a stock, charging handle and BCG. Palmetto has a nice lower parts kit with their enhanced trigger, Magpul grip and Magpul trigger guard for $70. If you want to stick with the current parts you listed, the KAK low pro gas block will work just fine. Quote HistoryQuoted:

ADCO says that dimpling the barrel is unnecessary. But if you're still determined to dimple, this tool makes it very easy.

A YHM clamp on GB costs about $33. Looks like dimpling 5 barrels would be break even for buying that tool. Haven't dimpled any barrels yet and haven't had any loosen up on me. I do like a clamp on gas block as a personal preference. Easier to install and adjust.
One part of the video indicates leaving a finger nail gap between the shoulder on the barrel and the GB. Not all GB needs that gap and most of the low profile GBs do not. Measuring the distance to the center of the rear set screw to the rear edge of the GB will provide the distance to the center of the port on the GB. The GB port is larger than barrel port to provide some misalignment tolerance, but I like to get them close as possible just the same. |

The gas block seat is 0.750" by my caliper, so I figured it had to be the block (I haven't measured it yet) that was out of spec. It shouldn't be in interference fit... So fine abrasive paper is up next! I had thought about building this upper for a while, but I hadn't done much about it until these barrels popped up. I'm glad I took the plunge.

After fucking with this barrel for about an hour, im about to call it a night. I can't get the gas block on. As in it hits the first taper and it's stuck. For fucks sake, it won't even go into the receiver. Looks like I'm going to break out the sand paper and fuck with it tomorrow. After I go drive 4 hours to go pick up my omega from silencershop.
