Geisler Defence 19x Recommended Build Tools

If you are like myself, you have built a fair amount of DIY firearms over the years.

From Polymer 80s to 3D printed Glocks, and even AR15s with the help of a drill press.

I recently had a friend reach out on the other end of the spectrum. Their first ghost gun build is the Geisler Defence G19x 80%.

You most likely stumbled upon this page by searching “Geisler 19x build tools” or something in that realm.

Lucky for you, I have the perfect shopping list to get you out from behind your computer (or phone. It’s 2024, after all) and onto the gun range.

I’ll include the bare minimum of tools to turn your chunk of plastic, aka unfinished Geisler, into a fully functioning firearm.

Do you have some cash to burn? Don’t worry—I’ll include some quality-of-life add-ons as well.

Geisler Defence Build Tool List

  • Cordless Hand Drill
  • End Nippers
  • X-Acto Knife
  • Dry Sandpaper
  • Wet Sandpaper
  • Dremel (Optional)
  • Files (Optional)

Required Geisler Defence 19x Build Tools

I will start by assuming you have zero tools at home and your X (it’s still Twitter to me) bio does not include DIY Master or God Tier Handyman.

I will include my favorite Geisler Defence tool budget options and an upgraded pick.

The upgraded product will not necessarily produce a better-finished 80% gun, but it will earn its place in your toolbox for the long run.

Below is the most minimal list I would suggest for your first Geisler build:

Cordless Hand Drill

To remove the trigger, locking block, and rear rail (trigger housing) pins of your Geisler frame, you need a solid cordless drill.

Do not cheap out; use a hand drill or USB-powered contraption. You want, at a minimum, a middle of the road battery powered drill.

End Nippers

Over the years, I have seen dozens of methods for removing the plastic tabs on 80% of frames. These tabs are located in the frame’s locking block and rear rail area.

The tabs are about a 1/2 inch in height and are a b**** to remove with files or sandpaper alone.

I’m about to save you a few hours. Order up a pair of end nippers and you can remove these to where the frame is nearly flush along the top. This will take a total of about 10 seconds for all four tabs.

X-Acto Knife

The X-Acto knife is needed to remove the plastic in the guide rod assembly channel.

I found the best technique is to slowly make small V cuts in this half-circle area until you are flush.

The key here is to go down as far as you can. A lot of malfunctions are caused here by the builder not removing enough material. This can cause the spring to get caught on the plastic and result in failure to feed, eject, or go back into battery.

Don’t rush this. Take your time.

While I use an X-Acto knife, other options include a box cutter, razor blade, or pocket knife.

Dry Sandpaper

The tabs are now almost entirely removed from your Geisler 19x.

How do we get them 100% flush with the frame? Elbow grease and sandpaper.

You will need several grits, slowly decreasing in coarseness, including:

  • 80 Grit Sandpaper
  • 120 Grit Sandpaper
  • 220 Grit Sandpaper

The brand here does not really matter, as they all get the job done.

If you are a perfectionist, feel free to go even higher in grit, although this is not necessary.

Wet Sandpaper

Here is the final step to getting that OEM, finished to absolute perfection, Geisler Defence 19x frame.

Wet Sandpaper.

You can pick this up online or at the local hardware store, and you will see “Wet Sandpaper” noted on the packaging.

Add a bit of water to this very high grit – almost smooth sandpaper and finish her off.

At this point, you will not be able to tell if any cutting, sanding, or modifications have been made.

Bonus Geisler Defence 19x Build Tools

Are you building only one frame? Are DIY projects not part of your usual weekend plans?

If it were me, I would skip this section to save money.

However, if you plan to build more 80% guns or are looking to beef up your home toolbox, grab the following:


Off the bat, this is also not something you want to cheap out on.

I have personally purchased several Amazon off-brand Dremel tools and ended up buying the real thing later.

If you’re going to buy something, buy it once and have a great tool for life.

Files are a VERY optional add-on. I have found them unnecessary after discovering better tools like the end nippers and X-Acto knife.

I understand that every person has their own preferences when it comes to building things, and you may find these handy or easier to use.
