Honestly, I did have of it in my bedroom and the other half on my workbench. Hardest part was getting the roll pin in the trigger guard and that was it. I thought I was going to have a hard time with the trigger and hammer but did not. Used the yellow JP springs, hope they hope with the trigger a bit.
Don't see a reason to buy a full lower anymore when assembling one is both easy and therapeutic

Thats kinda how I see it. Besides that damn roll pin for the bolt release and trigger guard, its real easy. Most of mine now are built. Some lowers are harder to assemble than others though.

Really I think the bolt release was the easiest. Taped the shit out of it, then just tapped it in like butter. |

Oh hell no on my lower both were tighter than hell.
Getting my trigger guard roll pin BACK out for a magpul trigger guard is proving to be a task. Going to work it partway out and get the vice grips and work it slowly out so I do not get a break in the lower. |

I had a few from a certain manufacturer that were really tight. Most of the time like you said they're real easy (especially with billet lowers) but for some reason this one companies just were hell to get in. I bought more of the same ones because except for that, it was GTG. I also use Daniel Defense LPKs because the pins are rolled and you can crush one end a little to start it off.

This was built with a Anvil Arms lower, RRA LPK and the JP trigger springs.

Now it's time for you to start assembling upper receivers.

Get a big bag of pivot pin detents. See how far you can launch them. It's a blast.
ETA: I make it a drinking game. |

Get a hocky puck and drill a 1/8 hole in it and tap it into the hole.. If you try to use vice grips and grop the pin to twist/pull the pin out it puts all that force on the ear and will most likely break.. |

I use the old clevis pin installation tool from the local hardware store.
Works great and the price is right.

There is no excuse for risking a launched pin when a clevis pin is only a buck. Buying replacement detents and springs will cost you that much not to mention the aggravation. And using razor blades, not this old man. I'd cut my fingers off. |

I've built a few lowers myself, and just helped my brother build his first. Very easy to do, just take your time. My brother isn't very mechanically inclined, but even he didn't find it to hard.

I attended Small Arms Maintenance School back in 2000 at Fort Drum. I was surprised how easy it was as well. To me the hardest part was always pushing down on the trigger group while getting the pin in - everything lined up. Of course it's noticeably harder with the 3-round burst, extra sear.

Use a roll punch to keep everything lined up, while you work the pin in from the other side. Easy peasy!

It isn't easy for everyone
I've actually found that a pair of vise grips with a little duct tape on one jaw (to protect the lower) is the best tool to use for assembly. |

I did end up with what appears to be a spring and a roll pin left over.
Function tested the lower and everything appears to be in place. Installed on upper and everything works fine. Very weird I had left over parts. |
