But the question is, do you have to change filters every 3,500 rounds

Not if you use synthetic bullets. you're good for 7000!

In my youthful days of gun tinkering, I kept towards the soda bottle idea of suppression. Not the 2 liter kind, but the 20 ounce version that the bottom was over-drilled and then covered from the inside with a piece of inner tube to act as an end wipe. The bottle was then packed with loosened 00 steel wool packed back into the bottle. SWD use to sell a threaded barrel adapter that took your 1/2 X 28 threads to soda bottle threads. I found a much simpler way and easier to get out of rather than unscrewing a lot of threads.

The inside necks of soda bottles are pretty consistent at .840 inches. So all you need to do is to turn your muzzle brake or bull barrel down to .835. Then an inch from the muzzle turn a small groove into the barrel. Poke a hole into the plastic soda bottle cap and you can drill it out or drill a smaller hole and use a rat tail file to expand the hole to the same diameter as the inside neck.

In use you put the holed cap on the barrel and then slide an O ring into its groove on the barrel. Then thread cap to bottle over the O ring and you'll have a nice air tight attachment of soda bottle to barrel. When it's time to quit, simply unthread the bottle a couple of turns (not all the way) and you can pull the bottle straight off the end of the barrel. The O ring comes off in the same maneuver so in a second you end up with a barrel that just has a decorative line machined into it one inch from the muzzle. Since you now can get into trouble if you just have parts that would make up a silencer, I don't know exactly what this would be? Legal on its own, but I guess that if you also had the bottle and O ring then it would be bad news. Smithy.

Hello from the Netherlands , I found also something on you tube ,my question is do you think this device is making your law makers in Washington happy ?

In my country its getting every year more difficult to keep on shooting with our sporting guns , we are still allowed to shoot with the AK47 type guns but if some moron from the government finds out that there is a device to make it full auto there is a bog possibility its going to be banned next year .

I was wondering how that works in your country .

Robert, that is a concern of mine, too. I can't see criminals using an oil filter suppressor. They're way too big. In my mind, it would be a very cool thing to try but really have no practical purpose.

But gun grabbers will take anything they can to try and make law abiding gun owners the crazy bad guys.

So I've got very mixed feelings about this.

I thought the same thing!

Do you have to have the stamp before you can purchase that adaptor?

Yes! Adapter $75. Stamp $200. Out the door, $275 plus incidentals.

The LGS I bought some .22LR at last weekend had made a sign for their front door showing a hand drawn oil filter suppressor sending the message that yes, they are legal and no, not for shooting in town. I figured they must sell the adapter but resisted (or should I say "suppressed") the urge to look at one.

You do know that the Stamp goes with the Serial number of the suppressor.You will not get a stamp for a homemade can...

The adapter has the serial number associated with the stamp. And while it would be simple to make at home, it would set you up for felony charges without the proper permits/licensing.

I see a ban on oil filters coming.

 

[jlh820]

Somebody is just making a legal registered one now, they have been around for at least 15 years that I know of.

Many states, like mine, have recently relaxed laws on suppressors so that while the idea may be dated, the sales potential is new.

Want!
