Changing out trigger guard

AR/M4 AR Technical Discussion

I did a couple of searches but found nothing. How hard is it to change out a standard trigger guard on a DPMS lower to something that I can use with gloves in the winter?

Very simple as long as you have the right tools. I changed my first one without a roll pin punch and it was much harder than it should have been.

  1. Purchase trigger guard and new roll pin.

  2. Put some lube in the hole where the pin is and let it sit.

  3. Using the correct punch and a brass hammer tap out the roll pin. Push in detent and remove.

  4. Re-install new trigger guard in reverse order.

I may be over simplfying but it really is not difficult to do with the correct tools.

Just be sure to support the ear on the lower as you knock the roll pin in or out, it’s actually pretty easy to snap it off.

Now that I have the handy instructions and video any suggestions for a new guard? Is the magpul guard a viable option or should I go with something that swings down to open the trigger area up?

I highly suggest using the Magpul triggerguard.

Roll pin punches have a little knob in the center to keep the punch centered in the roll pin, normal punches are flat and tend to move around the roll pin

Brownells has been kind enough to post some instructional videos:

Just make sure you get rollpin punches that are hardened. Last week I picked up a set of roll pin punches from Sear’s … I used the 1/8" punch ONE time on a trigger guard pin and it was badly chewed up. I’d say after one more pin it would be worthless.

I’d get this set and be very happy I think …

Hovey,

The key is using Kroil or other lube first to loosen the pin. It makes the job much easier.

This was a new lower build … I might guess a little lube would of also helped on the new install. Thanks.

Yeah I didn’t know about the lube, and it was a bitch installing the magpul guard on my 6920. I did support the ears though.

You can get a great deal on Kroil here: http://www.kanolabs.com/google/

I highly encourage you to look into the MIAD grip which comes with the trigger guard and can be adjusted using the removable panels. I am not a salesman but it is probably the best set up in the market.

Thanks I will look into that. I didn’t know the MIAD came w/trigger guard. I’m going to upgrade to the MIAD grip sometime in the near future anyway.
