>not building your own AR
Just buy a new one for like $6 if you can't find it. Your gun is still usable, the rear take-down pin will just want to fall out.

OP here
Update: I found it
How the fuck do I get it back in SAFELY? If I lose this thing again I'm probably going to kms

>>29850604

You can order a new one and yes the spring is rather important. I'd buy several

>>29850690
You're in luck because that's probably the easiest spring to place in the whole AR. Look it up on YouTube. It'll be a lot easier than trying to explain it. Next time take this question to the qtddtott

Yeah, this is my first AR. I just turned 18 last year and picked it up used. I didn't know much about guns at the time because my only other guns is a Savage .22 B Series I got for Christmas when I was 12, and a Nugget I got a year or so later.
I'm trying to decide on starting a build for a better AR or wasting my money on a slavaboo AK

>>29850604
I bought a spare parts set off of Amazon. Gave me 3 spares of shit that goes missing all the time. I easily put mine back in but I had to take off the upper first. Its ez pz OP. You got this.

>>29850604
Look on youtube "build ar lower".

now learn how your fucking weapon works you moron.

If I can't pull the rear takedown pin all the way out of the weapon, that means the detent is still in, correct? I'm hoping that didn't come flying out too

>>29850604

Next time stake your shit.

>>29850853
Yeah if the detent was gone the rear takedown pin would pretty much fall out
