Appreciate the help i didn’t have any idea on how to put on the sights. And man i love them i just purchased my first ar-15 and these sights are just perfect for now. I’m planning on getting me a acog scope.

bro i had flip up sights for like a year and didn't use them because i didn't install them right on my ar 15 then i watched your video today and put it on like its nothing thanks bro truly appreciate you

I lost my screws but the sights are on there TIGHT! You think I’ll be ok?

😊 Great video ~ Flip up sights are the first thing a person should install on there AR15. I know that iron sights are old school, but they seem to work just fine in the Vietnam war. 👍 I am just honoring are Vietnam veterens and thanking them for there service.

Thank you for showing us how to install our MBUS3 Sight! This was a huge help!

Thank you. Very instructive and helpful.

This video more helpful than the professional videos. Thanks

I don't know how I'm just now seeing this, but what a great video. The best part is the smile on your son's face at the end. The two of you did more than build an AR, you strengthened the bond between Father and Son.

My local gun shop here in Washington State had Anderson lowers for $30. Then our legislature went and passed the horrible “assault weapons” ban. Now they are illegal to buy here. I should’ve bought a dozen of them beforehand.

Very good video! Thanks for taking the time to make it. A couple things to consider next time you do this: 1. Add a drop or so of oil to each moving part BEFORE installing them. (Springs/detents for pivot and takedown pins, the pins themselves, trigger parts where metal meets metal, buffer, buffer spring and retainer spring/pin, etc.). This really makes the gun work more smoothly and reliably. 2. DON’T hammer on the trigger guard ears unless they are reinforced. This is a notoriously weak point on the aluminum lower and they can snap right off, ruining the lower. Insert the trigger guard, then lay the lower on a half-deck or so of playing cards (underneath where the pin goes in). This will support the ears while you tap the pin in. There is also a special vise tool that makes installation easy so you don’t have to use the hammer at all. Just look up “Trigger Guard Tool”. I am a professional gunsmith and have put together dozens of these. PSA makes a good quality product and solid parts kits. Have fun!

I like the rear placement spacing tip. Gets it as far back as possible but allows you to work the charging handle without the sight (when stowed) interfering with your fingers.

Great job..! I watched this a few months back before building mine. its a aero so a crew instead of a pin on the bolt release and integrated trigger guard. thanks for the upload

Thank you

Next project should be making your own lower from an 80% lower. Per the online reviews, best jig for it by orders of magnitude is the Gen 3 Easy Jig from 80% Arms. You'll need a handheld router compatible with its baseplate ($75 - $125), good hand drill without any runout or chuck wobble (usually from abusing its spindle wallowing out holes), and a garage type workshop plus a shop vacuum to suck up all the chips. DON'T do it on your kitchen table! It produces aluminum chips faster than a power miter or table saw does sawdust. Inform yourself about the 6061-T6 aluminum billet vs 7075-T6 forged aluminum receivers, and the strength differences of the two alloys before selecting the 80% upper. Plenty of online companies selling 80% AR-15, AR-10 and AR-9 lowers, and one that's Type III Hard Anodized will have a finish (except for the pocket you mill out) that's the same as other anodized receivers. The average user doesn't need to have the milled out part anodized or Cerakoted (especially with a 7075-T6). It's not going to be subjected to the same abuse, heavy use and environments as a "Duty Rifle" or a military one. Did a cost analysis on them. Don't expect this to be cheaper than buying your own lower, stripped or complete. It's not, even if you build a half-dozen. If you enjoy building stuff, building your own firearm could be the ultimate DIY project. I strongly discourage using a polymer lower. They're not strong enough and eventually break (easy to find examples of this online in reviews of them). The weak spot is around the buffer tube ring and where it transitions to the rest of the lower. They eventually crack and the buffer tube snaps off if not detected.

If you don't support the trigger guard ears when pounding in the roll pin, you can easily break the ears off and ruin the lower. Not hard to find rubber coated pliers handles of something similar to support the lower ear and you MUST keep the trigger guard in place to support the upper one while starting and driving the roll pin. I've seen lowers others have broken and ruined. Bolt Catch Roll Pin: I use a round toothpick with the tip cut off as a "slave pin" inserted from the forward side to hold the bolt catch in place while driving the roll pin in from the rear side. If you ever have to remove the bolt catch, drive it all the way through from the rear side. Don't try to drive it back out from the front. Roll Pins in General: Always helps to put a bit of gun grease or gun oil on a roll pin to help lube it a bit as you're driving it.

gave me the correct information. thank you.

I like this a lot :)

The castle nut for the buffer tube (receiver extension) needs to be torqued to 40 foot pounds..Then staked in two places..

I had to beat mine on with a rubber hammer

wow a 19 year old has to best DIY build video on all of youtube. Lucky kid to be taught such skills

Isn't the front site supposed to be flipped around

You gentlemen did a pretty good job with this video Very informative and helpful I thank you for this video I built my AR lower from this video Best of all your a father and son team

Thanks what you doing.

Lost My Mag Release Spring😢

Very Very Good video.. it is one of the best out there. You left nothing on the table and spoke clear and precise. Great Job!!!

LOL, after watching the bolt catch assembly, I was worried. I taped up the receiver, and put it in one of those littttel swivel vices to hold it steady, and also hold it in contact with the bench. I started the pin first, then put in the spring, plunger, and bolt catch. Much to my suprise, the roll pin went in the very first try. Not a single swear was needed!

Reading instructions is like trying to read another language. This videos was so helpful and I greatly appreciate you sir!

I will

Best video on building a lower ive seen so far. Very informative, thanks man.

Excellent video! Appreciate you explaining each step in detail through the assembly.

Used one for years , good video

Thanks for the tutorial, last time I tried this I almost burnt my dick off. Lol

keroheat junk maybe ok for use in a Chicken coop stinks waste of money buy a kero sun

Best AR build video, in my opinion, for first time builders. Great job on the video, excellent!

Great Build, Video, Father Son Project!!!!!!! My Only Question Is, Why The Hell Did You Make The #YoungMan Wait So Long To Build 1?? You Surely Can't Tell That It's His Time Assembling 1.

Great video, I followed along while building my AR.

Thank you for your assistance on this. I'm up in Austin, we had that "Snowmageddon" too and this year we felt we needed to get an alternate heat plan. 🙄 "They" say prices on natural gas are going to get ugly this year. QUESTION?? Do you by chance know if this is the same as Sengoku?? They look identical, even the box. 👀 I just received mine today and put it together, but I can't see if there is a wick inside or not. Do you have any advice?

Excellent tutorial and particularly appreciate the close ups.

Thank you God🙌🏻🙌🏻🙌🏻 thanks so much for this!!! I have bad adhd so reading is just not something I can sit still to do I’m a visual learner thank u so so much for this I bought my heater yesterday and put it to the side and if I wouldn’t of found this idk how long it would’ve been sitting thank you thank you🙏🏻🙏🏻🙌🏻🙌🏻

Both of you need to attend an armorer's class

Thank you! Your video is a life saver.

You sound like you are clueless. Is this the first time you've ever touched an assault rifle ?

First time setting up a kero heater and didn't wanna fuck it up so thank you for the video.

Great father and son project! I bought a Anderson Manufacturing A/R kit that came with a complete lower and complete upper, all I had to do was put them to each other and push the 2 pins in. It also came with a Vortex Red Dot optic all for $599.00 from my gun dealer. They also sell one without optics but comes with open iron sights for $499.00. It was decent deal since the optics are around $200 separately. The rifles are cheap but the ammo is still expensive.

I usually start with the trigger guard. If you break an ear off the lower your job is done.

Do u have to go through ffl

Well done video 👍👍

I’m already stressed about finding tiny pieces on a camo surface. 🤣

Quick question, with the palmetto kit did u have an extra detent and spring after completing the lower

Thanks for a great tutorial. You did the final inspiration I needed to take this on. Awesome job!
