    What kind of tools are needed for a PSA lower kit?

    Does PSA include instructions?

    I built my lower with a small hammer, a 1/8th punch, and a roll of duct tape. It helps to have a full AR15 punch set, and a mag well vise block but I got'er done with what I had in like 30 minutes and it came out nicely.

    Don't sweat it just make sure to support the ears of the trigger guard while your pounding on it.

    ^^ This

    Plus I use masking tape around the magazine release on both sides to avoid scratching the lower while installing the magazine release, and also around the bolt release when taping in the roll pin to avoid any scratches as well.

    I'm an AR newbie. I decided to build a lower. Tools & supplies I used:

    • Masking Tape
    • Electrical Tape
    • 5/32" Pin Punch
    • 1/8" Pin Punch
    • Vise Grip Pliers
    • Non Marring Hammer
    • Little Block of Wood
    • A $9 Castle Nut Wrench
    Just follow the instructions published on ar15.com.


    Things I learned while building a lower:

    1. Start the bolt catch pin from the magazine well side. It's easier to tap the roll pin to fully seat it from the magazine well side.
    2. Roll pin holders & roll pin punches would make things a ton easier. I now have a set.
    3. Brownells sells a Bolt Catch Pin Punch that has a flat side to make seating the bolt catch roll pin easier. I now have one.

    A common set of nail sets work very well for roll pins.
    A 1/4" clevis pin works EXTREMELY well for installing the pivot pin
    detent pin and spring!

    Both can be bought at Lowes, Home Depot, Ace Hardware,........

    I made one out of some polymer round stock I had, then I saw
    a post about the clevis pin. Those are .29c at the hardware store.

    Brownells has a very good video step by step on building the lower & AR in general. It's so good my friend had his 8 year old build a lower by watching it...in any case it's
    very easy. Make sure the hammer spring isn't upside down.

    I've watched those a few times. I find it funny that this is the video that ar15.com links to as an example of how to do a lower when he doesn't use the tools they recommend and mars the crap out of a couple of pins.

    I used a small rubber hammer, vice grips, painters tape, electrical tape, a razor blade (to hold the front take down detent in place), and castle nut wrench.

    Just watch and read a couple how to videos. The right tools would have made it easier, but you can make it work. It wasn't even frustrating not having the right tools, if thats worth anything to you.

    ETA: No lpk come with instructions.

    I bought one of these and used the same tools most everyone else has mentioned. The lower from PSA just came in some bubble wrap. No instructions.

    I found these videos pretty good. A little long winded.

    That's good info kdw. Thanks for posting that link to the tools, that is cheaper than buying them separately.
