Halo 5 Nerf Railgun

The massively successful Halo 5: Guardians came out more than 5 years ago, and I have been a huge fan of it right from the beginning. Just to be honest here, the railgun is absolutely NOT my favorite gun in Halo, but it looks so nice! I finally decided to design this gun, so let's get started with this Instructable!

Step 1: 3D Print and Glue

Make sure that you print out eleven of the pegs so that you can have some spares in case you lose some of them. So once you have all of the pieces printed out, take two pieces, and place two pegs in one of them. Then take E6000 Glue and apply it to one of the pieces. Place the piece with pegs in it onto its corresponding piece, and make sure to peg in the holes. Tape the two pieces together, and leave them to dry for a few hours. Repeat this with all of the front pieces, and all of the back pieces(The back pieces are the two that screw onto the front section and lock the gun in place.) Make sure NOT to connect the back and front pieces!

Step 2: Apply Spray Filler

For this step, I simply took Rust-O-Leum Automotive Filler Primer and gave each piece two coats. I decided not to use wood filler on the seams because I didn't mind it too much for this project.

Step 3: Base Coat

For the base coat, I used some brown paint, but in hindsight, I probably should have used silver for the base, so that anything that scratches off of the top layer will reveal the metal look underneath it, so i recommend that you do that instead.

Step 4: Mask Off and Spray

Now, this is the most tedious part of any prop build, but it is also the most rewarding part. I masked off all of the parts that I wanted to remain brown, and left open all of the parts that I wanted to be silver(But if you did a silver base coat, then you need to do the opposite).Then I hit it with some silver spray paint and waited for about 30 minutes for it to dry. After doing that for both pieces, take off the masking tape to reveal the prize of all of your hard work.

Step 5: Take a Look at How Awesome It Is

Yeah... it's pretty cool looking!

Step 6: Adding the Nerf Gun

For this project, I used the Nerf Firestrike. Place the Nerf Gun unto the back piece as shown, and then slide the front piece over it. Then use two M7 bolts on the back piece and screw them in to hold it all together.

Step 7: Weathering

For this step, I used Rub N' Buff, which is a wax paint that is useful for weathering. In order to apply this, take an old cotton sock and place it over your hand. Take some of the paint on your fingertip and rub it into a paper plate to make a thin layer of it on your finger. Now this is the perfect example of "A little goes a long way", so use it very conservatively. Apply a small amount to corners and edges to give it a scratched and weathered metal look. Be sure not to apply it too close to any of he silver parts, as the color is very similar to the silver shade, and it can begin to just look like a bad paint job.

Step 8: Enjoy Your Completely Finished Gun

I decided not to paint the Nerf Gun, but it probably would look nice, and I may decide to do it in the future. But, aside from that, I think this prop came out looking really nice, and I plan on doing more of these in the future, so if you have an idea for a project you would like me to do, just leave a suggestion down in the comments section and i'll check it out! Thanks!
