PART 1 of 2: How to assemble an AR/M4 lower receiver

If you follow me, in this video you might learn a little more about me.

This video is to show how to assemble an AR/M4 lower receiver, using basic tools (No fancy blocks, mounts, etc...) I try to show a few easy ways to do things, based on my years of experience. Its a simple process anyone can do at home.
Lower receivers are "the firearm" and have to go through an FFL, but for $50 you can buy a stripped lower (along with FFL transfer fees, which tend to be going up as the FBI charges more to maintain an FFL).

Why buy a stripped lower? Cost. If you want an AR/M4, you can buy just the lower for $50 and then pay a $25-$50 FFL fee. Other parts can be bought later., as you can afford them, through the mail or at gun shows. Another bonus is you are buying a stripped lower, that you can "build as a pistol". If you bought a complete rifle AR/M4, made by a company, its a rifle and can never legally be a pistol, unless you get a tax stamp/SBR/register it, and then you have worry about selling it later or doing paperwork to change it. A pistol you build, can stay a pistol, or be made into a rifle and back, based on the law. The AFT has put out, a pistol can be converted to a rife and back to a pistol, but a rifle must stay a rifle. Don't risk becoming a felon, making a rifle into a pistol .

TIPS (you might fail to read);

DO NOT USE ANY LOCTITE.
USE A RAG TO WORK ON.
USE OIL/GREASE ON METAL TO ALUMINUM PARTS.
LINE THINGS UP, AND TAP LIGHTLY AT FIRST.
USE TAPE OR CARDBOARD TO COVER THE RECEIVER (so you don't leave marks if you miss with a hammer/punch).
USE A LARGE CLEAR BAG TO INSTALL SPRINGS/DETENT PINS (as they might fly off).
TIGHTEN THE GRIP AND CASTLE NUT, THEN BACK OFF, AND RETIGHTEN (season the threads).
STAKE YOUR CASTLE NUT, IF COMPLETE AND A SELF DEFENSE USE (non range toy).
BE CAREFUL WITH THE TRIGGER GUARD EARS TOWARDS THE REAR WHEN INSTALLING THE REAR ROLL PIN, AS YOU COULD BEND/BREAK THEM.
