| i ahve built a lower before but this one is giving me trouble. the roll pin for the bolt catch keeps wanting to go in at a slight angle. and when i put the bolt catch in, i can't get the pin to go through it. anyone have any secret ways to do it? im using a regular hammer, maybe a different type? |

I get the pin started with the catch in but not aligned. Then I use a cheap automatic center punch with a modified tip to finish driving the pin while the catch is aligned with a SILGHTLY smaller diameter pin from the front. Roll pins have a slight taper, if not, turning them in a Dremel tool against a honing stone will put a nice bevel on the front end.
The automatic center punch replaces the punch and hammer. I just ground the tip to a very broad point, it still works as a center punch. |

You really should use the proper punch designed to put in this roll pin crimp one end of the roll pin use a bit of tw25 use an allen key as a capture pin +1 I have done it with and without the proper tools, it can be done eather way, but much easier with proper punch... |
