Roll Pins
I have driven a fair number of roll pins in the last 40 or so years. I have owned a nice set of Matco Tools roll pin punches for a long time and they have served me well. I must admit however, it was in the last few years I even learned there was such a thing as roll pin starter punches, but I didn't see where I needed them. I don't as a habit build AR15's, just have always bought complete rifles. I did just put a lower together out of necessity and it's of course no big deal. BUT there is that pesky bolt catch pin. I knew I was gonna scratch the brand new lower if I kept on so; my new set of roll pin starter punches arrived today. Man I love buying tools.

Now all you need is a BFH. 0 -
Installing the bolt catch is my least favorite part of AR assembly- I dread it. The right tools make the job much easier: 
This master AR tool kit from Real Avid contains every tool you need, as well as a few that you probably won't use, to assemble an AR in record time. They have an excellent dealer program, but if you tell them that in addition to being a dealer you do gun smithing, they'll sell you a single kit at a DEEP discount.0 -

when I started building the kit ar's out of curiosity and of course so many parts on the dang internet PSA sales and a few weeks of cold weather a few years a back and eight rifles later
,,I bought a set of starter and roll pin punches after I built a couple nothing fancy and would bet they were made in china . before that it was what ever punch I had in the tool box and also learned early a piece of tape ( what ever is on hand masking , electrical , duct ) is your friend when putting in the bolt release pin
in with or with out the correct tools just a strip in front of the roll pin hole and no scratches on the receiver , 0 -
Roll Tide!!
Wait,
What?

I use a couple of strips of electricians tape on the side of the lower to prevent hammer marks.
Also, I no longer use "spring pins" but have switched to only "rolled" pins. These are WAY easier to install/remove and make a nicer looking assembly.0 -
I just love it when a technical post turns into humor
