I’ve always installed the gas tube into my adjustable gas blocks before I install on the rifle. Easier to work with and just use small drill bit from back as a pilot to keep roll pin holes lined up as one hammers the roll pin through gas block and tube. Good video

[@arshooter1]

attach gas block to tube before installing to receiver. Whole lot easier.

[@M21-w1y]

Get the gas block to where it’s aligned correctly on the barrel, tighten the set screws to where they DO leave a mark on the barrel. Remove the gas block, dimple ( drill) the barrel where the set screws left their mark, reinstall the gas block, locktite the set screws. Support the gas block while you are installing the gas tube roll pin, don’t use a center punch as a starter punch and don’t use the side of the hammer, use the hammer head to hit the punch. Your welcome.

[@DJT-2024]

Agreed. When assembling my Aero build, I noticed the barrel wasn't dimpled. I had to do as you suggested. It's not something I thought I'd have to do. I just dealt with it and went on.

[@someguywithnoplan6395]

No

I installed an adjustable SA on my AR10, called for .025 gap from collar. Luckily I had shims, but no video I’ve watched mentions this?

[@dannybarton940]

Thank you. I was just sitting here pondering those same thoughts. The roll pin starter punches are less than 10 bucks on Optics Planet.

KAK dumpling jig. You're welcome.

These ar10 videos are super helpful. Building my own aero precision ar10 soon. Parts are in the post.

Put a piece of spaghetti in the barrel gas port and break it off at the surface of the barrel. Then slide the gas block on and turn the barrel and block over. The spaghetti piece will fall into the gas block and act like a keyway centering the assembly. Then tighten the screws locking the block in place. Almost done now. Turn the barrel over again letting the spighetti fall back into the barrel. Run a cleaning rod down the barrel breaking the spighetti and pushing it out. Run a patch down the bore making sure it is clean... Done.. It is lined up.

[@JeremyElliott]

Raw or al dente on the spaghetti? Seriously, thanks for the tip.

[@codyhanthorn4270]

That is a super idea. Except the spag I had was to large of diamter to fit.

[@andrewjohnson6907]

This is all way easier if you put your gas tube and block together first and then install block and tube as one sub-assembly.

[@Regular_1094]

Looks like a dpms 308 to me, you should explain that instead of just calling it an ar10. Ar10 pattern is different from dpms pattern and it would help for novice and beginner builders so they don’t end up getting mixed up.

[@BadDadio]

I agree with you. Many so-called AR10 are actually AR308. The AR10s are proprietary to Armalite and many parts aren’t interchangeable. I like the AR10 moniker better because it doesn’t specify caliber, unlike the AR308 implies .308 but can be many different calibers.

[@clk27us]

There are different gas block size options on the aero precision website. How do I know what size to get. .750, .936,.875? I’ve always bought complete uppers. This is my first complete build. I have the enhanced upper with a 20” barrel in .308. Any help is greatly appreciated. Your videos are super helpful. Thanks for taking the time to make them.

[@zacharydavis1659]

The website where you got your barrel/complete upper should say what the profile size is. Also called Gas Block Journal.

[@richardmanning7601]

Do the barrels usually come with the hole in the barrel for the gas block?

[@1stShotTactical]

Yes!

[@richardmanning7601]

@@1stShotTactical Thank you and Merry Christmas

[@tvelaify]

Why did you select the heavy barrel? Just curious as I'm trying to decide on a barrel. I would like something that will last a long time, but also I want to carry it without it being too heavy.

[@1stShotTactical]

Good question! I found it on sale and was trying to do a “budget build” for this lol… not gonna lie it’s pretty heavy, this barrel works great but I would recommend a light weight version for sure!🙌

[@tvelaify]

@@1stShotTactical Ok. That is helpful feedback. Thanks!

[@chadmiller8019]

I have the heavy barrel as well snd i want to get an adjustment gas block but how do i know what size gas block to get

[@johntran4478]

the manufacture should state the diameter.

[@1stShotTactical]

Check you barrel manufacturer website and they will tell you the right size!🙌

[@jamesdempsey5917]

Did you get that bend in the tube by the barrel nut by hand?

[@1stShotTactical]

That’s how the gas tube comes to fit into the upper🙌🙌

[@mrscassafrass]

Does the gas tube have to align with the teeth on the barrel nut like an m4?

[@johnfritz8571]

For this particular set up on the Aero enhanced upper receiver the barrel nut does NOT require timing to allow the gas tube to insert in the upper receiver.

[@jonathant.clayton5400]

Do you check for head spacing? I haven’t yet but I hear how “important” it is. I have been doing this exact build (my first full build) but with WC barrel and gas system. Enjoyed the videos!

[@meaculpa7779]

You don't really need to with aero parts or If all the parts are from the same manufacturer. Unless you are upgrading the bgc it can wait, aero parts are all plug and play

7:15 you were what???
