How To Make Airsoft Silencer

Introduction

Building a silencer for an airsoft gun is a popular pursuit for many. It requires both engineering and safety knowhow since you're building something that includes a lot of potential moving parts that can be potentially risky. Here, we'll go over the eight steps to make a homemade airsoft silencer and some of the most important considerations to keep in mind while doing so.

Step 1 - Choose Your Supplies

Materials you'll need for a homemade airsoft silencer will depend on the specific design you have chosen - typically either metal or PVC. Common supplies are a PVC pipe, several caps, a threaded coupler, foam, and of course all the appropriate tools to affix the parts, such as saws, drills, taps, epoxy glue, and nuts.

Step 2 - Cut the Tubing

You'll need to take a careful tool to measure and cut PVC piping according to the design specification. Here, be sure to include two holes for the coupler - one on the inside and one on the outside.

Step 3 - File the Internal Rim

Now, you'll need to take a file to the inside rim of the pipe - be sure to file down the burr that has been created on the inner and outer walls of the pipe. This will help avoid damaging the threads which are essential to assembling the silencer.

Step 4 - Create the Foam Insert

Now, you'll need to create the foam insert that will provide some sound dampening for the silencer, in addition to preventing any feedback loops between the inner and outer walls. To create this insert, take foam (of your chosen thickness) and cut it into a ring, to fit snugly inside the pipe. Cut the foam larger than the inside length, so that it will be slightly compressed when inserted.

Step 5 - Assemble the Silencer

Now you will need to assemble the silencer, connecting the parts you have prepared together. Begin by connecting the coupler to the two rims, one on the inside and one on the outside of the pipe. Secure both sides by tightly attaching the nut. Once attached, fill the tube with the foam insert, pressing it in firmly.

Step 6 - Attach the Endcaps

Connect the end caps to the PVC coupler and again secure it with the nut. Make sure everything is attached firmly, with no risk of coming loose when fired.

Step 7 - Test the Silencer

Now that the silencer is constructed, you'll need to test it out to ensure it works properly. Attempt to fire at a target at a shorter range, in a well-ventilated indoor space - be sure to wear appropriate safety equipment such as eye protection. Check to see if the silencer reduces the sound of the shot to an acceptable level.

Step 8 - Install on the Gun

The final step is to attach the constructed silencer onto the airsoft gun. This can be done with a simple threaded coupler. Be sure to attach the silencer securely so that it won't become loose when fired.

Summary

In summary, building a homemade airsoft silencer requires a certain level of engineering knowhow and caution. The eight steps to build such a silencer include choosing the right supplies, cutting and filing the tubing, making the foam insert, assembling the silencer, attaching the end caps, testing the silencer, and finally, installing it on an airsoft gun. If done properly, this homemade silencer can provide noise reduction to an acceptable level.
