How to Make a Remote Control Gun
Remote Control Camera
To make this project, we started with our DIY remote control camera project.
We’re going to use the same motion control base we’ve built for the remote control camera in the previous tutorial. First, remove your camera so that you can replace it with an airsoft gun or firearm.
NOTE: This project was designed for use with a remote control airsoft gun. The responsibility of how the remote control gun is used rests with the builder of the project. Survival Life is not responsible or liable for the way you use the information found on our site.
Supplies you'll need
- Existing control motion base (from remote control camera tutorial)
- Airsoft or firearm pistol with a quad rail mount (For this project to work, it is important that your gun has a quad rail mount.)
- Rifle Sling Mount
- Scope Rail Mount
- Bicycle Brake
- 1/2″ Plywood
- Phillips Head Screwdriver
- 5mm or 3/16 drill bit
- surface mount bolt
- 1 x #10-32 1-¼” screw
- 4 x #10 ¾” screws
- 3 x #10 1-¼” screws
- 2 x #2 1-¼” screws
- 5x30mm Hex bolt1 Small compression spring
- 1 x medium eyelet
- 1x small eyelet
- 1 x 20′ Bicycle brake cable and cable housing
- 2 cable stops
- 1/2″ Metal Pipe
- 1/2″ Mounting Flange
- Electrical Tape
- 1/2″ Cap
How to Make a Remote Control Gun
Attach the Gun to the Motion Control Platform
Step 1: Rest the Gun on the Platform
With the base of the gun handle resting on the platform, the quad rail mount should be flush with the top of the platform. Depending on the size of your gun, the platform may need to be cut to the desired length with a saw.
Step 2: Measure Base to the Top of Platform
Measure the distance between the base of the motion platform and the top of the motion platform wall.
Step 3: Measure Height of Sling Mount
Measure the height of your sling mount, and add it to the distance you measured for the height of the platform wall. For us, the total distance was 5 inches. Write this down as the height for a piece that you are about to cut.
Step 4: Measure Platform Width
Measure the width of the platform wall. We measured 6 inches for ours. Write this measurement down as the width of a piece that you are about to cut.
Step 5: Cut the Measurements
Cut a piece of ½ inch plywood to be the height and width that you’ve written down. We cut our piece of plywood to be 5 inches by 6 inches.
Step 6: Fasten the Sling Mount
In the upper left corner of the plywood, align your sling mount flush with the edges and pre-drill a hole for your #10-32 1¼ inch screw. Place your sling mount over the hole and fasten it into place with a screwdriver.
Step 7: Mount the Gun into the Rail
Attach the remote control gun mount to the sling mount by sliding it into the quad rail and tightening the knob with your fingers.
Step 8: Cut a 9-inch Long Plywood
Remove the gun from the motion control platform, and cut another piece of plywood to be the same height as the existing platform wall but 9 inches long.
Step 9: Drill and Fasten the Two Pieces Together
Remove the gun from the sling mount and install this new piece onto it by pre-drilling and fastening them together with 2 x #10 ¾” screws.
Step 10: Mount the Piece to the Platform
Mount this piece to the existing motion platform with 2 x #2 1-¼” screws.
Step 11: Trace Outline of Trigger in Both Forward and Back Position
Attach the gun to the sling mount and trace the outline of the gun with a pencil. Trace the outline of the trigger in the full forward position.
Trace the outline of the trigger in the full back position as well.
Step 12: Measure Board to Platform Edge
With a measuring tape, find the remaining distance from the board to the edge of the platform. We measured 3 ¼ inches.
Step 13: Cut Another Piece with the New Width and Length of 9 Inches
Cut another piece of plywood to have a width that’s the distance you’ve just measured and a length of 9 inches. Cut a notch in it for the gun handle to slide into.
Step 14: Fasten Board to Base of Platform
Pre-drill and fasten this board to the base of the motion platform with 2 x #10 ¾” screws.
Build the Firing Mechanism
Step 1: Drill the Knob Out
Remove the bolt from the mount. If the bolt has a knob, drill it out from the other side with a 5 mm drill bit. If you don’t have a 5 mm drill bit then a 3/16 inch drill bit will work. Once you’ve drilled the knob out, drill another hole on the other end of the bolt. Place a nut on a 5x30mm hex bolt and thread the bolt through one of the holes as shown.
Step 2: Mount Base of Surface Mount
Draw a straight line through the outline of your trigger on the plywood. Use 2 x #10 1-¼” screws to mount the base of the surface mount bolt over the trigger and on the line.
Step 3: Mount Eyelets
On the straight line, mount two eyelets. Insert a medium size eyelet furthest from the bolt, and insert a small eyelet closest to the bolt.
Step 4: Insert Cable Through Eyelets
Insert a cable with cable housing through the eyelets and thread it through the other hole in the bolt.
Step 5: Secure with Cable Stop
Secure the cable with a cable stop.
Step 6: Insert Surface Mount Bolt
Insert a #10 1 ¼” screw in front of the surface mount bolt on the straight line. Leave it protruding as shown in the picture.
Step 7: Place Compression Spring
Place a compression spring over the screw that you’ve just inserted and the screw in the bolt.
Step 8: Reattach Gun
Reattach your gun to the sling mount.
Step 9: Insert Metal Pipe into Mounting Flange
Take a ½ inch mounting flange and insert a ½ inch metal pipe into it. We used a ¾ inch flange with a ¾ to ½ inch adapter because the store was out of ½ flanges.
Step 10: Place Electrical Tape on Top of Pipe
Place electrical tape toward the top of the ½” pipe. Give yourself just enough room to fit the bicycle brake and a ½ inch cap over the end of the pipe.
Step 11: Drill Hole on Bicycle Brake
Before you put the bicycle brake on the pipe, drill a hole through it as shown. See the video for more details.
Step 12: Thread Cable Through
Thread the cable through the body of this bicycle brake and the hole.
Step 13: Put Tension on Cable
Pull the cable taught and use a cable stop to maintain the tension.
Step 14: Assemble Bicycle Break and Pipe
Assemble the bicycle brake onto the ½ inch pipe.
Step 15: Mount Flange
Mount the flange onto your control board.
Assembling and Mounting the Camera/Scope Attachment
Step 1: Attach Camera to Rail Mount
Use a 1/4” – 20 x 1” bolt to attach the camera to the scope rail mount.
Step 2: Attach the Scope to Rail Mount
Attach the scope in front of the camera on the scope rail mount.
Step 3: Attach Scope on Upper Rail
Attach the scope rail mount to the upper rail on the gun.
Step 4: Hook Camera to Television
Use the cable that came with the camera as well as a long extension cord to hook the camera up to your television.
Step 5: Test It Out!
Turn your television on and test it out!

What do you think? We think it is super stealth and could not believe how inexpensive it was to make a DIY security system of this caliber. All the parts should be readily available at any local retailer, and the camera we use is just an ordinary video camera. Nothing fancy here, just 007 cool!
Isn't this remote control gun project the coolest thing you've ever seen? Share your thoughts in the comments section below!
