First use a razor blade to cut a notch behind the front sight so that the whole piece can be removed. Then push on the fiberglass to slide it off. Do not pull it off from the other end as the alignment will be thrown off. Use a sander, grinder or 80x sandpaper to smooth out the hardened rough surface. Next, grind the sides down about halfway, but do not grind past the point where the front sight makes contact. Cut it down until the barrel fits snugly and easily. Stand the glassed brake line upright in a vise.
Mix a small amount of resin and use an eyedropper to fill in any interior holes or air bubbles until the solid fiberglass is level with the steel tube end.
This will give the junction between the brake line and fiberglass coupling added strength. Acetone can be used to clean the eyedropper. Cut the PVC tubing to the desired length. A longer silencer will be necessary for more powerful cartridges. Drill a large hole in the center of one end cap, making it large enough to fit on the fiberglass end to the point where the front sight makes contact. Wrap masking tape around the end cap to cover the holes. Stand the cap with the inside tube inserted into a vise.
Get the cap level and straight with the brake line. Resin fills the small holes, making the tube strong enough to withstand the muzzle blast. When the inside is hardened, turn the assembly over and fiberglass around the backside of the end cap for added strength. Avoid getting resin in the opening where the barrel fits. Place the finished cap and inner tube on one end of the PVC tubing that has already been cut to size. Center the brake line as you look in the open end of the PVC.
Sharpen one end of the drill rod to a point and use it as a center-punch. You would need to consult your local laws as the answer could depend on your state, city, etc. It should, but you would have to modify it slightly.
Make the spacers at 2-inch intervals between the steel wool. Not Helpful 53 Helpful Hypothetically, how would I attach it to the barrel? Wouldn't slide interfere or prohibit me from attaching it? Slide would not interfere, because there will be a metal clamp held together by a screw.
The clamp will hold the inner pipe to the barrel without being permanent. The tighter the screw is, the tighter the hold is to the barrel. Not Helpful 17 Helpful Does this work with air rifles, as I have problem with varmints in my back yard and do not want to scare people when I shoot at them?
It would. Bear in mind the notes as to response and sonic barrier, however. If your projectile exits at supersonic speed, at sea level, in dry air, you would still hear the sonic 'crack. The distance can vary. Generally, you want to have it on far enough that it will remain centered. So, 1 inch will do just fine, but adding extra inches won't hurt. A lightweight suppressor doesn't need as much attachment as a heavyweight suppressor.
Not Helpful 9 Helpful 9. You can purchase them a sporting goods store or online. Most also require co2 or high pressure air. Not Helpful 9 Helpful 8. Unfortunately, a homemade suppressor like this one won't work very well. The way a suppressor works is by deducting from the response of the gun. A gun makes two sounds: the response, which is the gunpowder igniting, and the bullet breaking the sonic barrier. A paintball gun only has a response. Since this is just PVC pipe, it lacks the necessary components to silence any form of projectile.
Not Helpful 31 Helpful Not Helpful 35 Helpful This is made for use with a paintball gun, not for use with a real rifle. Not Helpful 8 Helpful Include your email address to get a message when this question is answered. Make sure you smoothly sand out the suppressor barrel. Imperfections may cause irregularities in firing and damage to your suppressor. Helpful 2 Not Helpful 3.
Have a professional manufacturer inspect your suppressor before using the paintball gun. Helpful 3 Not Helpful 6. These instructions are only for a suppressor that can be used on a paintball gun. Helpful 3 Not Helpful 2. Suppressors are illegal for firearms, meaning any weapon that shoots a projectile by an explosive force. The suppressor described in this article may be legal but only because it is built for an airgun and cannot be used for a real firearm.
Helpful 3 Not Helpful 4. Make sure that your paintball arena allows homemade suppressors. Helpful 58 Not Helpful Never point a paintball gun, or any other weapon used to fire projectiles, at a person, pet or flammable or breakable object, except in appropriate paintball events.
Helpful 33 Not Helpful Under ATF law It is illegal to build a silencer for anything that fires a projectile without a permit.
Some states ban silencers altogether, and because many paintball gun silencers can be used for firearms as well, they too may be illegal in your area. Check your state's laws on this matter before proceeding. Helpful 2 Not Helpful 2. You can make a suppressor quieter by putting a few drops of water or oil into the suppressor and it'll really reduce first round pop.
First round pop is caused by the burning of cold dense air inside the suppressor--after the first shot the suppressor is filled with burned gasses that cannot burn when the next shot is fired. The downside is the liquid will mix with powder residue and stick to the suppressor interior and hasten the need for cleaning.
Placing a rubber washer between each baffle freeze plug or storage cup and between the last baffle and exit hole should help attenuate internal noise caused by reflection, vibration and resonance. Lowe's and Home Depot sell rubber washers in a variety of sizes. A suppressor cover or wrap can also reduce noise from suppressor vibration. Some silencers of the past used felt washers between the last baffle and the exit hole to absorb the diminished shock wave.
Another technique of old was placing steel wool in the gas chambers but testing seems to confirm this isn't worth the trouble. A thick piece of rubber sheet can be placed between the last baffle and exit hole to form a "wipe". Cut an "X" slit for the bullet to pass. The rubber will slow the exit of gas from the suppressor exit hole but may reduce accuracy.
I highly recommend you put a little anti-seize compound on the barrel, tube and end cap threads to make removal and disassembly easier. To remove stuck baffles for cleaning a socket on an extension can be used to drive them out.
Don't forget that you must engrave your Form 1 information on the exterior tube of the suppressor. About half the time this is all that's required to break the flash hider loose. Remove all washers and lock nuts from the rifle muzzle because they can throw off suppressor alignment. The best alignment usually comes from seating the suppressor directly against the muzzle thread shoulder.
Rob also spent 10 years as a federal law enforcement officer. He enjoys all forms of rifle and pistol use. M16 4-Way Select Fire. Leupold RX It will take three months to a year to get the tax stamp so send it in early. You must wait to begin building your suppressor until you receive the tax stamp. The 9mm Tavor uses a blow-back action so it functions without a suppressor "booster". Introduction My homemade. It's not like in the movies where all you hear is brass hitting the floor.
My Blackout suppressor is very comparable to my Silencerco Osprey 45 commercial suppressor but they're much louder than a suppressed. Something else Hollywood gets very wrong is the sound of a bullet striking flesh--it's loud. When hunting with a suppressed rifle the reduction in muzzle blast allows you to hear the bullet strike. A shot to an animal's chest with a subsonic Blackout round sounds like a two-by-four body smack.
Hollywood really does need to pick up on this for a little extra realism. Here's a short high quality stereo mp3 recording I made of a suppressed Blackout shot where you can hear the muzzle blast, bullet whizzing by and the target impact.
It was a yard shot with the microphone about 70 yards downrange. The impact is as loud as the muzzle blast. The bullet was a grain Sierra MatchKing boat tail bullet. Speaking of subsonic bullet flight noise, the US Army's Silencers: Principles and Evaluations report found that streamlined boat tail bullets were much quieter in flight than flat base bullets such as the Winchester or pistol bullets.
I decided to go with an all aluminum monolithic baffle design for a Blackout suppressor as my first suppressor build. It's very good at sending heavy grain bullets at subsonic speeds downrange accurately. If I were building a suppressor for. A single steel engine freeze plug can make an excellent supersonic rated blast baffle. They come in many different diameters. An all aluminum suppressor should only be used with subsonic ammunition.
The fast moving gas from supersonic rounds will quickly wear away aluminum baffles. All gr 9mm and gr 45 ACP ammo are subsonic. I have used the. A " twist. A twist. Low velocity bullets spin slower than full speed rounds so a tighter twist is needed for heavy and slow subsonic rounds. Trail Boss pistol powder works well because it's fast burning for less muzzle blast and it's a low density powder that will fill more cartridge space for more consistent subsonic velocity.
A spring and piston decoupler or "booster" allows the barrel to move back and cycle the pistol without the suppressor initially moving with it. Because of this the non-booster suppressors on this page will not work with recoil operated pistols. Blow back pistols, like most. Rifles, of course, will also work with the suppressors shown on this webpage.
Pistol caliber carbine rifles are a great fit for homemade non-booster suppressors because they do not use pistol style locked breach operation. Also their heavy, large diameter bullets hit hard at subsonic velocity and their longer barrels allow fast burning pistol powder to completely burn for less muzzle blast.
They make excellent home defense weapons for these reasons. I absolutely love my Tavor X95 bullpup in 9mm with a homemade suppressor but a 45ACP carbine would add some stopping power.
I'm a big fan of holographic and red dot sights for subsonic weapons due to the typical short ranges used. Pistol iron sights are also a good match for subsonic shooting. The BLK suppressor is 8 inches long. This size suppressor is what I recommend for all calibers except. For my. I have built. The extra length really helps quiet a short pistol barrel. Note how the outside diameter OD of the baffle matches the inside diameter ID of the tube.
If you have difficulty knocking the baffle into the cover tube with a plastic mallet then remove more metal from the outside of the baffle to slightly reduce its diameter.
The seal can be a press fit, welded, epoxied, one or more small screws, or even duct tape. Two or three small screws around the end of the suppressor works well for this purpose. I have Form 1's and tax stamps for all three. I use a chop saw to cut the round bars and tubes. A vice and hack saw can also be used because facing the bars and tubes in a lathe will true them up.
Facing the Suppressor Baffle On the Lathe Facing the suppressor baffle ensures a precision fit and alignment when the suppressor is screwed onto the rifle barrel. Face both ends of the baffle and tube. Facing the baffle and tube will also make it easier to mount them square in the lathe. The depth of this hole isn't critical because it will lead into the large blast baffle but it needs to be deep enough to allow the suppressor to screw onto all the thread offered by your rifle barrel. Longer baffles will need to be supported on the lathe by a steady rest shown holding the baffle at near end.
The tail stock holds the drill bit stationary and in perfect alignment while the lathe spins the baffle. Optional Boring For the Tap Boring the tap hole to the pre-tap size. This is not necessary if you have the correct size drill bit as listed above. Tap the Baffle Thread Tapping the baffle-- Do not use lathe power to do this. I used the tailstock to simply hold the tap for perfect alignment with the bullet path. The tailstock is loose so it can be pushed by hand into the baffle.
I turned the lathe chuck by hand to start the tap. I did the last half of the tap using a standard tap hand wrench so I could feel when the tap bottomed out. Finish the Tap By Hand Finish the tap by hand so you can feel the tap bottom out. Shorter suppressors like this can be worked on the lathe with only the lathe chuck holding the baffle no steady rest needed.
Drilling the Bullet Path You can flip the suppressor baffle around and drill from both ends to keep from having to use a long drill bit. The bullet path drill bit will be smaller than the thread hole--see below for bullet path drill bit sizes.
