| So, after watching some videos, I'm interested in wipe caps, but they're not currently available for the suppressors I would most like to use them on, namely a Rugged Surge, Obsidian, and Oculus. It doesn't seem like it would be a difficult thing to make, the end caps for all three have a lot of space inside, so I'm sure someone like Curtis Tactical or Ecco Machine could easily modify them with a wipe holder, but I'm curious if there would be any issue using wipes on suppressors that aren't specifically designed for them. Anyone have any experience or technical knowledge here? |
| I thought wipes were made unavailable by the ATF ruling that they are suppressors, instead of just replacement parts. So if a company puts wipes in their suppressors, and wipes don't last for very many shots, you have to go through the whole ATF 200$ tax and license hassle in order to replace the wipes. |

You can replace wipes yourself they can’t sell them to you Dead Air wolfman takes rubber faucet washers

I could certainly modify or re-make most end caps to take a wipe, but I've discovered two things with wipes:
1, they don't drop SPL very much on otherwise good performing cans 2, even though the meter may show a reduction, they can create a higher pitched sound, almost a chirp/whistle that is more offensive to the ears than the higher dB but lower frequency noise without them. |

Could the chirp or whistle be from the bullet getting knocked off axis by hitting the wipe? what kind of wipe material was it? |

They also change the accuracy of the weapon to an 8" group at 10 yards and you must run only FMJ bullets. You are far better off with a 1/2 teaspoon of grease periodically injected into the back if the can. Quoted:

Didn't some of the youtube testing show the Vox is louder at the ear when wiped (on a semi auto). Seems the wipe was increasing back pressure and port pop. I know when it comes to pistol suppressors the locked breech/slide pistols and wiped cans work really well together ala KAC snap on and Aurora. Once you allow that slide to reciprocate you're getting a lot of crud back in your face and port pop as the path of least resistance. I really don't have any interest in wiped rifle cans due to the potential accuracy degradation (though I see the impressive Vox results above). Makes more sense on a pistol can. |

Quoted: Weird, I haven't noticed such high pitched noises with my Vox S. Sounds great. The acoustic phenomenon is akin to what happens when you let the air out of a balloon; if you pinch the end to where the pressure escapes more slowly, you may get a high pitched squeal/whistle. It's the same when pressure is trying to escape through a wipe that closed back up behind the bullet; end up with the right combination of pressure, hole size & hole shape, you get a new sound. I get no detectable pitch change with my wiped .22 LR and .25 ACP stuff, but I've had it happen with 9mm. I've never messed with wipes in a rifle can. |

The NFA Review Channel on YouTube showed this with the Vox and a 300blk bolt gun. Almost like a whistle coming out of the wipe. |
