Want to do an AR build with some bros. However, they're a bit skittish about people who aren't gunsmiths using parts from different manufacturers to build a device that houses explosions.
What's the worst that could happen if a person were to throw together an AR:
1. Mating a Pre-Made upper to a pre-made lower?
2. Mating a Pre-Made upper to a self-assembled lower?
3. Assembling the Upper and Lower from parts?
Alternatively:
TL;DR - Want to build an AR, what could possibly go wrong?

you try to shoot back but your gun doesnt work then the atf shoots you

They aren't normie liberals but also aren't /k/ommandos or "gun people".
The other reasoning brought up was that have a sour taste in their mouths from car parts/consumer electronics replacement parts/etc not being to spec and they're afraid it's going to blow up.

The companies will point fingers at each other when something doesn't work/it's a lemon, unless you buy from a single company.
>2. Mating a Pre-Made upper to a self-assembled lower?
See above, but if you use no-name or gun show special lower parts it adds another avenue for companies to fuck you instead of fixing something defective

If you have to ask then you probably will cut corners in assembly, like not using Aeroshell 33MS when installing the barrel nut, or not torquing to spec, or not staking the castle nut, or all the other shit that gets skipped on bargain rifles and can result in parts seizing, breaking or falling off. The problem with self assembly is that anything that goes wrong is on you. Maybe the parts manufacturer will take responsibility but that's going to be relatively rare.
When you buy a complete rifle you pay extra to be taken care of with a warranty and to get a rifle that passed test fire at the factory. Your friends are dumbasses for thinking a gun that headspaces itself can just explode, but you need to realize that for a lot of newer gun owners and non-enthusiasts that don't have experience fixing everything going wrong themselves, warranty support will save a lot of headache.
