This is PART Two (2) in the How to do it....

Warning: Silencers, homemade or otherwise, are illegal in the United States unless you have a federal license.

Post: This post is in response to some who have over the course of this blog asked me to tell them how to build a home made silencer. This was emailed to me last month, and the how to instruction source are unknown. I do not keep emails.

Make Shift, Homemade Silencer/Suppressor
for 22 Caliber Model AR-15 Rifle:

Step 1: The Gun Purchase and Conversion Kit
Purchased was a used AR15 civilian model semi auto assault rifle.
Then purchased was a 22 caliber conversion kit.
.223 rounds are too expensive to shoot. However, 22 caliber rounds are fun and relatively inexpressive to shoot.

Step 2: How it was made
You'll need a three foot long one inch diameter PVC pipe.
In the end of the pipe, drill random 1/4 inch holes, the entire circumference of the outside of the pipe. Make approximately 14 holes. Now hang the pipe up, spray paint the pipe with black enamel paint. Let dry thoroughly. Apply second coat, let dry.
Now wrap the barrel where the silencer is to slide over with electrical tape, approximately 14 to 15 inches of the barrel length. Wrap it with one layer tightly.
Next wrap the same area with white teflon pipe tape.
The drilled hole portion of the PVC pipe should extend past the end of the barrel.
Now slide the silencer over the end of the tape portion of the barrel.
Note: It should be a tight fit.

Several experiments of PVC length pipe led to the conclusion that 15 inches over the actual barrel plus another 21 inches (36 inches total) were adequate to suppress the 22 caliber long rifle round. This does make the rifle barrel and overall length of the gun 21 inches longer. A tripod makes it easier to fire than hand held or rest it on something like sand bags.
