Looking for Tips on My First AR Build

[rg115]

Been kicking around the idea of building my first AR-15, and I finally dove into the parts search. I'm finding some decent deals, but honestly, it's a bit overwhelming. Just trying to figure out what's actually worth it and what's not.

I'm thinking of sticking with a basic rifle build, probably going with 5.56 to start. I've heard it's a good choice for beginners, but I'm open to any suggestions if there's something better.

Are there any brands you all would say to avoid? And what about those sneaky hidden costs that pop up? I've read about some rookie mistakes, but it's hard to know what to watch for without actually going through it.

Part of me wonders if I should just buy a pre-built one instead. I know it saves time, but I'm really interested in understanding how it all works.

Any advice or stories about learning the hard way would be super helpful. Thanks in advance!

If you already have an AR-15 in 5.56, you might consider the .223 WYLDE chambering for your project. It would be compatible with 5.56 NATO and .223 REM ammunition and is supposed to offer better accuracy than 5.56 NATO.

5.56 is a good choice because of the availability of parts and ammo. Also you can use the cheaper .223 Rem in a 5.56 chamber.

As far as brands, check reviews. It seems everyone hates or loves a brand for one reason or another regardless of validity. Lots of reviews give a better cross-section to make your choice. You are looking for Milspec dimensions.

Watch a lot of videos on gun friendly platforms. Brownell's has a good video series on their website and School of the American Rifle (SOTAR) on youtube is your friend.

If you want hands-on experience building an AR but don't want to experiement on your brand new uppers/lowers, take an armorer course and pound on their guns.

Good luck!

Take your time and Google Google Google lol when I built my first one I broke it down into 2 lines upper & lower then broke them into 2 more I went with matched upper & lower then I started Google searches on barrels once I decided what barrel I liked and the lenght I wanted i went checking company's and reviews then I set out deciding the handguard I liked I can tell you aint but two bcg's I run either a wilson combat -auto or a BCM Bolt Carrier Group - Auto
The lower is basically up to you I prefer magpul for stock And grip the lower inter section is all based on what you want to spend. Almost all my builds I use Spikes Tactical enhanced lower parts kits. Google is your friend check out a few builds and really ask questions.

I've got 7 AR's of different makers. For a first time buyer, I'd go with one from Palmetto State Armory. You can usually get one for under $500. If you want to learn how they work, watch a YouTube video and take yours apart and put it back together. There are a few tools you'll need, Vice block, AR wrench and a decent punch set.

I am going to follow up on WD714.
I am under the impression that you do not have experience in the AR field. Correct?

Us guys down here have a saying, The KISS principle.
Keep It Simple Stupid, Please don't be offended. It has been said/used on all of us one time or another.

If you're anything like me, buy a couple of these! Saved me a few times.

If you never bend a safety detent spring, you're a better man than me. Or launch a buffer tube detent across your garage at 0200.

A spring out a BIC lighter will work.

Or a pivot pin detent.
My safety glasses say they have never done that, but they have been known to lie once or twice. so maybe!

I am not going to be working on anything at 2am but rest, it will be done well before then or "mañana"

I still have no idea where mine went.

Buy uppers.

Build lowers.
