I just used my new Geissele roll pin starter tonight after installing my new Criterion barrel. The whole operation took about 1 minute to correctly install the pin. No stress at all. Great precision product.

I don't have Geissele roll pin starters, but I do have generic roll pin punches.
It can be done without them, but having the right tools does make the job a lot less stressful. |

So, it is made only for 5/64" roll pins; which on an AR, the gas block / front sight base is the only item using this size roll pin. |

The correct tools make it easy.
The Kitchen Table Gun Plumbers Union would frown on this, however. If the ol' lady doesn't have it in the kitchen junk drawer, you don't need it.

It's a good tool. For those on a budget or not wanting to wait for shipping a short piece of brass tube and a slightly longer piece of spring steel rod available at most hardware stores works pretty well. The brass tube should have an ID slightly larger than the roll pin you want to start and the steel rod should fit in the brass tube.

First time assembling an AR, I bought these:
http://www.squirreldaddy.com/Hollow-End-Starter-punch-p/sd20-206.htm and they made the Wheeler roll pin punch set I bought at the same time look like a pile of crooked toys. I have a garage full of tools and the Wheeler punches are the ugliest pos I actually paid money for. Already looking for their replacements. |

Small hemostat. Been using them for years with no issue. It allows one to check proper alignment before one realizes the pin was going in crooked.

ebay has generic ones on the cheap. they are helpful for those little pins. the one I bought is double sided for two size pins with an outside diameter of .223 so you can slip a shell casing over it to protect it from hammer blows. i think it was around $5.

I just use a piece of 1/4" brass stock and drill the end to the size of roll pin needed.

I even drilled out the opposite side to hold my roll pin punches. It's like a long punch so I don't have to worry about hitting the reciever with the hammer. |

Or.... you could simply use roll pin punches and run scotch tape around both the punch and pin.
Sometimes unique tools are just.... well..... silly

Can anyone tell me the roll pin sizes for the bolt catch and forward assist? Another option for the bolt catch is .094 x .438. Sometimes the .500 length is just a tad too long on some lowers. There is a seller on Ebay that sells the stainless coiled roll pins cheap. The coiled roll pins are so much easier to install. Trigger guard - .125 x .625 Bolt catch - .094 x .500 Forward assist - .094 x .625 Gas tube - 5/64 x 5/16 Front sight swivel - 1/8 x 7/16 Gas block/ CH latch - 5/64 x 5/16 |

I grab a roll pin about 1/4" from the starting end with a pair of needle nosed pliers and pinch the heck out of it before tapping it with a small hammer to get it started. Once it's started I use a regular roll pin punch of (hopefully) the correct size vs. the pin. Seems squeezing that starting end makes it start easier.

430 channel locks with a bit of tape make trigger guard pins and bolt catch pins stupid simple.
