Hi everyone,

  Planning on installing the Magpul enhanced trigger guard, and it looks straightforward, but the little instruction sheet says to remove the old roll pin and install the new one in accordance with "accepted armory guidlines."  Since this is my first time doing this, I figured I'd better ask you all before I screwed something up.  What's the proper way to remove and install?  I don't have any special roll pin punches, and I'm not conerned about saving the old roll pin.  I was planning on knocking the old one out with a small pin punch, and driving the new one in with a mallet.  What should I be doing?  Thanks!

SUPPORT THE LOWER RECEIVER "EARS".  Dont just start banging it with a hammer because there is a good chance you'll break the lower ears off the receiver.  Support them with a block of wood or something of the sort while driving out the roll pin and while installing the new roll pin.

Makes sense––-just stick a block as close to the hole as possibe, at the bottom, and should be good to go?  Will a 1/8" pin punch be sufficient to remove the roll pin?

I use a block of wood with a hole drilled into it for the departing pin; that supports the ear on all sides of the hole.

MMcfpd - thanks, that's what I'll do.  Do you know what size/type punch you use?

There should be a Sticky or tutorial on anything to do with Installation or removal of Trigger Guard Roll pins to avoid ear/lower damage for beginners & first timers (If there is one please link it for us who are fearfull of damage to our builds)

+1 that'd be great.  Found tutorials on almost everything, but not this.

ETA:  My mistake.  There is a pretty good set of instructions in this how-to thread:

I just can't believe how easy it apparently is to break off a tab from the lower by driving the roll pin––I figured worst case would be destroying the roll pin.  Seems awful fragile, no?  Now I'm a little bit hesitant––last thing I want to do is kill my pre-ban receiver by trying to change a trigger guard.

Instead of using a hammer to install the roll pin, try this. Use a pair of pliers to slightly compress one end of the roll pin so that it will start to insert in the hole. Use a pair of water pump pliers with some tape in the jaws to press the pin in place. Works like a charm. It also works for the bolt catch pin.

A small c-clamp will reinstall the roll pin and virtually eliminate the possibility of breaking the receiver. Use a cloth to protect the receiver, couldn't be easier.

IMO, this is the best way to do it.  It's the safest to the lower, and it will also prevent idiot scratches (I've done it).  I prefer any method that does not involve impact, and I would recommend giving this a try before you hammer it in.
