Speaking of that front takedown pin. I bought a pre-ban Colt AR-15 that had the screw front pin. So I go to the local gunshow and found a captive push pin. Then I field stripped a butane lighter for the spring. For the detent pin I cut down a finishing nail and rounded off the point.
I held the spring and nail down with a jeweler’s screw driver as I slipped the push pin in.
Just finished my first, mostly on the cheap. Mixed parts from wherever I could find the best deal…total Frankengun. Seems to have turned out OK. Haven’t zeroed it yet, so I can’t speak to accuracy, but I have test fired it and it does run. Tweet you a pic in a few.
I encourage you to do a full build from parts. It’s fun. And you get exactly the AR you want. I suppose the latter doesn’t matter much, if there’s a vendor selling the exact AR you want. For some of my parts, I just waited until I found a good sale price.
Anyways, vendor shipped me the wrong no-go gauge. Right one showed up Friday. Busy weekend, but I’ll get going on it, now that I’ve checked headspace.

Hardest part? That dust cover. Aside from that everything is following directions. If you can use a torque wrench you’ll be fine.

What he said. Freaking front takedown detent on a lower is way harder to me than anything on an upper

The Modern man should build an AR-15 from top to bottom.

Sounds like a nice project for the Winter Months. Go for it.

Brownells has an excellent set of videos up on YouTube covering assembly of both the upper and lower on the AR15 . I used them for my first assembly .
