Started building my first AR15

[TDIfan]

After buying 2 Aero Precision lowers in late 2019, along with Luth AR lower parts kit, and an Sba3 pistol brace I decided to put one together. I started by looking at this website for instructions:. https://www.arbuildjunkie.com/assemb...ower-receiver/

After we put the boys up for nap, I headed down into the basement, cleared off my reloading/work bench. Gathered all the parts and tools I needed and began assembly. I got the Mag catch on, the front pivot pin, spring, and detent in (on the first try) and the bolt catch, spring and plunger in. All without boogering up anything or losing any parts. By then the kids were awake and I had to put it aside. All in, maybe 1 hr so far. Got to hand it to Luth AR. Their kit is blister packed with each piece having it's own spot and numbered with the names of all the components. Seems pretty easy so far. I'll post again as I progress.

Congrats! And welcome to the addiction.

Bolt catch roll pin has always been my downfall. Can't put one together without marring my lower (even just the slightest).

electrical tape.. cover the part of the lower that you hit/ remove when done

This tool right here for bolt catch roll pin.

Cover the receiver with tape as stated above.


Or, buy an Aero M4E1 lower, and use the Allen screw instead of a roll pin.

I've tried punches & done the tape thing. I even used Plasti Dip on one build... Still busted thru it & marked up the lower. Also ruined a nylon jawed parallel plier while still making a mark on the lower.

It's just something I'm not adept at. Sharpie has become invaluable.

Thanks, I'm feeling good so far about it. And I'm pretty confident in my assembly skills. There might be a slight blemish at bolt catch pin hole, but not anything like some of the bubba pics I've seen and no bare metal. I did use roll pin punches (something I would have appreciated in my R/C car days) and they helped to easily get those pins started. Although a longer punch would have made the bolt catch pin easier to put in. Like the website described, I covered everything in 2 layers of blue painter's tape to protect from damage when doing the bolt catch. I put some oil on every pin before attempting to drive them in. Also, I forgot that i got the trigger guard in too But might change it out to a glove friendly one instead of the straight one that came with the LPK.

They're cheap enough. If you may need the extra room, just go ahead and do it.

Looking for dvds in boxes Ive had put away over a year ago for when I move

Those blemishes are character that make it your own. Enjoy!

get one of those plastic lower blocks you can clamp in a vise
get an automatic center punch from HF and grind it flat, start the bolt catch roll pin with needle nosed pliers and use the centerpunch to knock it in put masking tape under it while you work
When doing the retainer pin detents get a box from an upper with the foam in it, and work with the lid halfway open, you still might lose the detents and springs, but this will increase your chances of finding them
