Want to change out a trigger guard, will have to tap out the roll pin.  Leery of breaking off an ear.

Besides using a copious amount of kroil, heat gun and supporting the ears are there any other tricks ?

Go slow, make sure its supported on the actual ear

I have a block of wood with a small hole drilled in it that works good at supporting the ears and still allowing the roll pin to fall through. Another thing you could try is to take a dremel with a cut off wheel and cut the roll pin at each end so there is less to drive out of the ears, but if you need to save the pin this wont' work.

If you break the ear off then you can buy a grip with the trigger guard built in.

ETA. make sure you use the proper size punch(preferably a roll pin punch)because the pin is large and has quite a bit of resistance on it and the last thing you want to happen(besides breaking an ear off)is to drive the punch into the pin and get it stuck.

Cut the trigger guard in half w/ a Dremel, cut the remaining bit in half again, roll pin halves are easy to push out.

Unless you no clue at all what you are doing, and the question and reasoning you posted shows you know what you are doing, you will be fine. I use a roll of duct tape half the time. What matters most is the correct size punch. You can drive it out in two three strikes like butter

I have driven out, I have no idea how many, buzzed half the time, never once broke an ear off

Try this method if you have a drill press.

This tool is handy for trigger guard roll pins
Amazon Product
  • Comes with an install pin and an uninstall pin
  • Pins conveniently store in the frame
  • Durable construction, made of aluminum with a mil-spec anodized finish



The full roll pin punch kit is a good buy for a basic armorer set.

I’ve never had to use heat, even on a tight Colt lower. A little oil and a good drive punch and medium weight hammer.

I use the Real Avid Master Bench block. The lower fits perfect and is supported properly.  Pins are driven from bolt catch side to ejection port side.

This.

Just swapped the triggerguard on my DD lower and it was easy. Only chipping was from when DD installed the original MOE triggerguard in 2009.

I will add the only lower that gave me pause was an Anderson. The pin holes are a little tight and took a little more effort than I would have liked but it worked out okay. As long as the ear is supported and you're not using a mini sledge it should be okay. Kroil isn't a bad idea if it's been a few years or lots of field use.

I tried the RA bench block, once, and found that there was a gap between the "ear" and the actual block.  I had to support the receiver to get it mated up.  The receiver was a standard, forged receiver, so I can't understand why it wasn't fully supported.

As an aside, I once used a stack of playing cards to support the ear in a pinch.  It worked just fine, although it was a bit awkward.

Unless you're acting like you're Thor, you shouldn't break it off. Don't use a huge hammer or mallet and instead use a small, tiny brass hammer and use the correct sized punch and give it a good support.

I have a small 2X4 with a small hole drilled just for knocking out trigger guard pins.  Keeping the lower ear supported is key.

And two that you don’t need. But to each their own. A piece of 1x6 pine has probably been my most used tool. And not just for AR’s.

Wheeler tool.

As mentioned multiple times.  There's no reason to do it any other way.  It's full proof.

The only way to go....listen to @DefenderAO on this question....

They are cheap and very easy to use

It seems to me that most people overthink this stuff. I assembled my first lower with only a pair of vice grips. I've probably assembled and disassembled dozens since then without any "special" tools.

Wheeler Trigger Guard removal and installation works pretty damn good; however I still use a 2x4 with hole drilled out to at least start. The old fashion way still works well

A little more expensive than the Wheeler roll pin tool, but Little Crow Gunworks makes some really nice AR-15 tools.  I have used almost everything that they make for years.

Only on the internet will people crap on using a tool that might save some time or minimize the risk of damaging something.

Not everyone has extensive trigger guard experience. I've used both the punch method and the tool method and lemme tell ya, I'll take the tool method every time. YMMV.

This is the actual one I use but is the same concept as Wheeler.

When working on a 1500.00+ AR, I don't understand not using the most full proof way to change a trigger guard with ear damage being a material risk for those not having done this work before.

Agree, especially when working on a NFA SBR lower....even with the Wheeler tool, I was sweating changing out the trigger guard on my SBRs....

This the way. Use an armorer’s hammer and correct punch. I’ve never broken an ear, but I’m always careful with these.
