Thanks for the video. I just picked up my stripped upper yesterday. As a first time builder I would like to mention something to others considering their first build. Unless you know someone who has all the required tools for a build and will lend or rent them to you, don't start your first build thinking it will be your only build. You will be buying some specialized tools.

[@lifehacksformen8427]

I'm loving your Playlist. Building mine now. But word of advise. Never loosen with a torque wrench. It voids the calibration. Use a ratchet for that.

I'm new to the AR building game and I'm enjoying your videos, thank you. But I have to say brother, as an old man who has made his living with tools for 50 years, you have to invest in a proper set of roll pin punches, both starter and regular as well as a set of brass punches. Oh, and a proper bench block. Again, thanks for the video, they are very good quality.

[@PoliticallyInsensitive]

A hair dryer or heat gun is a useful tool as well. BCM mills their uppers to be slightly small (to aid in accuracy they say). I'm in the middle of a Grendel build and I'm waiting for it to cool down in Colorado so the barrel will shrink slightly (because it's cold) and the upper will be slightly larger (because I'm going to heat it) so I'm hoping it slides in just as easily as yours. One method one used in the past to line up the gas block is to plug both the muzzle and the chamber and use a duster can. You'll hear it when it's lined up properly.

[@Hoverton-vd7nw]

I'm not bashing 1st shot because I don't know what checks you performed prior to the video BUT.... Safety is paramount when doing this. What I would say is that the steps to insure the barrel is properly headspaced and examined prior to assembly is very important to show in a build video. After all this is the most critical part of the build in terms of safety. Your audience is looking to you for knowledge as most lack the knowhow to do this safely. It is not a difficult job building an AR but it is important that you show the safety aspect as well. I would not forgive myself if I caused injury or worse to someone as i am sure you probably would not either.

[@stemialert1]

If you buy quality parts from a reputable supplier, why is the headspace ever in question?

[@ColdWarVeteran-r2j]

Do a video.

[@hairydogstail]

The Midwest reaction rod will prevent the barrel from clocking in the index slot of the upper receiver, worth every penny. Clam shell holders will put stress on the barrel's index pin and won't prevent barrel clocking... Anti-sieze is not the best, it will harden and can cause problems, use AeroShell Grease 64 as recommended in the TDP specs..Put the grease on the upper barrel threads, in front of the barrel lip and around any shims.. I lap the upper receiver face and bed the barrel in the upper with green loctite.. I dimple the barrel for the set screw type gas block and use a little green loctite around the barrel journal to seal the gas block to the barrel journal.. I use Rocksett for the gas block set screws as even red loctite will fail with heat..Blue loctite is worthless on gas block set screws..Pinning can cause accuracy problems, especially with a .625 barrel journal.. The best adj gas block is the Riflespeed. It has made all other adj gas blocks obsolete..

that torque wrench looks like a harbor freight special so this is a possibility since their quality is questionable. in general, however, untorqueing fastners with a torque wrench is not a problem. in fact, many sensitive mechanical components (ex. engine head studs and the like) have an untorqueing procedure to prevent warping parts that requires using a torque wrench.

Great video. However, torque wrench gears are not designed to loosen bolts that are tightened. That lever is in case you need to switch directions to get the gears inside the head unstuck.

[@phrankus2009]

Thanks! ... But what about head spacing ? ? ?

[@daynasanders1107]

Head spacing is built into the barrel extension and bolt. If head spacing is incorrect then the barrel extension and/or bolt are out of spec. You can't adjust head spacing on an AR without replacement parts.

[@macgyver5108]

Those Wheeler clamshell vise mounts are actually pretty "risky" to use, as they transfer all the torque from the barrel nut into the _receiver_ which can cause your receiver to CRACK!😬 Instead you want to use a "reaction rod" tool, they're a long bar/rod that slides inside the receiver and has splines which mate inside the barrel against the bolt lugs, that means all the torque is applied to the barrel instead. You can typically find one for around $45-100 bucks.

Well, this young man did a decent job of throwing a barrel on a upper receiver. That’s about all you can say, was it done right? Hardly. Was it worth making a video as a guide for others to follow? No. Too much was taken for garnet that it would be right solely on the premise that they were “ quality” parts. I myself have used from the same manufacturer and they are high quality parts and pieces, but I always check all my tolerances and fitments for my own piece of mind. Saying it was “high quality “ parts after it blows up in your face doesn’t mean much. Parts are parts, how the parts are assembled are key to building a safe and dependable rifle.

If you don't remove the dust cover, you won't be able to get the tool for aligning the gas tube out. The spring loaded pin on the inside of the dust cover hangs up on he tool. I just went through this and after some thought, I aligned the small "C" clip so I could see the two ends of the clip. I used 2 small screwdrivers . One on each of the "ends" and tapped the clip off. It came off like a breeze. Just watch so the clip doesn't decide to take a cruise around the kitchen. I then pulled the rod out of the cover from the rear "stock end". That's it. I have my first ever AR-15 close to being finished. I think I went over my budget but that's okay. Wheeler needs to modify the mold for the plastic pat that holds the gas alignment rod, You can't get it out "IF" you have the dust cover on. The first two flanges toward the front of the tool can't get by the dust cover spring catch on the inside. Then you would have to take the dust cover off. God Bless America. We need Trump back or else we're screwed.

If you have an ar-15 barrel that isn’t headspaced correctly, it needs to be sent back to the manufacturer. Bad headspace means the barrel extension is set wrong, which then means the gas port is drilled in the wrong place.

[@seaweeb2258]

Depends. Figure out what way your headspacing is out. If the bolt won't close on a go guage, you can sand the boltface back a little bit. Not much, and is dependent on HOW much it is out of tolerance. If the no go guage fits, then there isn't much you can do other than sending the parts back to the manufacturer. If a field guage closes, you might have to form 1 the gun as a destructive device because it's close to a hand grenade at that point.

Can you give me the sites where you found the gas block tube and gas block and barrel set

[@1stShotTactical]

[@BasementOps]

60 ft pounds is the torque spec for that hanguard?

[@1stShotTactical]

Aero says between 30 - 60lbs of torque for the barrel nut👍👍

[@Ronin-1867]

first we're going to go ahead and just go ahead with this video. and then were going to go ahead and never watch another

[@1stShotTactical]

😂😂 sorry I’m autistic

[@UltraReefReseller]

What about the spacers and timing?

[@65cbtengr]

Mil spec gun grease on the upper threads and barrel extension

[@damianalvarez5570]

What length is the barrel

[@Vandallolwut]

did you use the shims? how did you see if it was head spaced?

[@Subtlenimbus]

The shims for the barrel nut have nothing to do with headspace.

[@raytruck5799]

Did you forget the pin for the barrel that mates to the upper?

[@timkeller1742]

Why would the gas block need set screws if it is pinned?

[@1stShotTactical]

More secure! There’s a lot of pressure moving thru there👍👍

[@atranimecs]

Why not? more the merrier

[@nickadams2951]

Why did you remove the dust cover?

[@1stShotTactical]

Yup that was a big mistake as I pointed out in the video😅😅😅 I thought it would fit better in the clamshell in the vise. Def keep your dust cover on tho lol

[@nickadams2951]

@@1stShotTactical magpul makes one u can just pop on if u still don’t have one

[@necavenue]

How come you didn't show the shims installation?

[@1stShotTactical]

Mine didn’t require any, it lined up perfectly!👍👍
