How to Make a Halo M7 Sub Machine Gun Prop

Ever wanted to build a halo weapon? Well here's a guide to get you started, without the hassle of pepakura, resin, fiberglass and all those nasty chemicals.

Step 1: Gather Materials

You need paper, pencils, cardboard, glue, some sort of tube for the barrel, styrofoam, scissors, hot glue sticks, a hot glue gun, and a reference image. Here's a good image.

Step 2: Create Blue Print Using Reference Image

Carefully make a blueprint of the SMG, noting the details and lines, you will use them later.

Step 3: Trace and Cut Out 4 Slices of Blueprint

Be presice, use an exacto knife, and then cut it through with scissors following the exacto knife lines.

Step 4: Find Barrel

You have to be a bit creative with his one. Find some sort of tube object that can be used as a barrel. I used a disposable tooth brush container. Then, cut the two slices of the trace to fit the barrel, and then place the other two on either side.

Step 5: Cut Out Details From Blueprint

At this point you are going to cut the remaining pieces from the blueprint following the lines. That way, you can create slices for your details.

Step 6: Trace and Cut Details Onto Styrofoam

Instead of using cardboard, we are going to trace this on styrafoam, a thinner, cleaner solution to the problem!

Step 7: Cut and Glue on Stock

Using the same method for the body, cut out 4 slices of the stock, and then glue it on the back using hot glue. Keep it in place for 1 minute after glueing to make sure it is sturdy.

Step 8: More Styrafoam!

Eat out pieces from the styrafoam to cover up the ugly corrugated sides of the cardboard base. That way, the sides look cleaner, as for the top of the gun, I used a piece of paper and glued it to make a rounder seeming top.

Step 9: Cut Out Sights

Cut out 4 semi circles for the sights.

Step 10: Glue Stuff Together

Glue everything together EXCEPT the right side main detail. We are going to do something cool with that later.

Step 11: Paint :D

Use a flat coat of matte black spray paint or black acrylic paint on the whole gun. Wait for it to dry.

Step 12: Details

Using a crafting knife, carve out details from the gun. I also cut a rectangle for where the bolt would be, colored the part silver, and then glued the top slice on top.

Step 13: Finished!!!

And that's it! Now go make a suit to go with that too! :P

I love bungie and 343!!!

    What would be cool, is you could make a socket in the back of the cardboard that would allow the stock to be ajustble.

    hey there! i do believe you can. If you look up on youtube, theres a guy called "DaFrontlineTrooper" that specializes in making props out of EVA foam.

    not at all! in fact, it would be more stable to make them together. I made the stock and gun separate because I didn't have cardboard long enough for the whole smg.
