    Finally got around to putting my AR together. I bought a complete kit, minus the stripped lower. When I went to put in the LPK last night, I looked and looked and couldn't find my punch set. So in an attempt to get it done anyway, I grabbed my spring loaded center punch. What an awesome idea for setting the roll pins. It's pointed, so it self-centers in the roll pin. A few punches from it and the springs were set. So much easier than using a hammer and a punch set.

    It's just a cheap one like this from Harbor Freight.

    Short story: If you're assembling an AR lower, use this.:bowdown:

    Not worried about it flaring out the roll pins?

    use vice grips to install the roll pins, not a hammering or pinning motion, you will flare the ends

    I've never assembled an AR (yet), but wouldn't a soft-faced hammer be the best tool to prevent maring the finish?

    use vice grips with the ends taped up to prevent marring
     
  6. There are punch sets available that are specifically for roll pins. They don't flare the pins.

    The ones in my kit were rolled 3 full times. i.e. 3 layers thick. They did not flare even the slightest bit. Besides, if they did a minimal amount, it would be fine by me as it would help hold it in place better when seated fully.

    I used the opposite side of a meat cleaver for the pins.

    I used vice grips with electrical tape on them, and put painters tape all over the lower so I didn't scratch it. Worked flawlessly I had the lower assembled in 30 mins. First time ever too.

    I think there's about a million ways to do it that would all work. I've used flat faced punches and they work fine even as long as you have a steady hand :big grin:

    Vice grips are much easier than a punch set

    I have completely stripped my lower and put it all back together and I simply used normal pliers (flat-nose and needle nose) along with some brass punches, regular hammer, and some electrical tape.
