What type of anti-seize (if any) compounds are people using for user-servicable suppressors? Any negative effects?
Thanks |

Don't use copper-based antisieze on aluminum. On stainless, it's GTG.
If you have an aluminum can, just use moly grease if you can get it, otherwise any firearms grease will work. Heck, you can use "plain red grease" and it'll work just fine, it just gets a little dirtier is all. |

I put a little antiseize on the threads of my sparrow No problems yet Where do you get it? Are you using the stuff for spark plugs from an auto parts store? That's dielectric grease, which means it contains no conductive metallic coponents. It's basically silicone grease without additives. It's not good at really high temperatures, but for a .22LR can you'll be just fine. |
| I got a new SSsparrow. After the first cleaning I put Dupont Krytox on the threads in the supressor, and on the gun threads. That was a mistake. It kept unscrewing from the gun, or disassembling itself every 10-20 rounds. Luckily I didn't get any baffle strikes. I cleaned it again with mineral spririts and a bore brush, but didn't lube it again. I'm playing safe. We'll see what happens next. |

There are TWO primary metal-based anti-sieze compounds available at an auto-parts or larger hardware store: -copper based (don't use on Aluminum as TrojanMan points out), and -nickel based If you have ever purchased a NEW Glock, you probably noticed the COPPER based stuff on the frame rails. For steel/inconel cans, copper is probably OK, but not for aluminum. Don't know if the nickel would work for aluminum (anyone?). |

Here is what is in YHM's offering: "Anti-Seize is a heavy duty blend of aluminum, copper and graphite lubricants in a petroleum base. Use during assembly to prevent galling, corrosion and seizing and to assure easier disassembly. Inert, will not evaporate or harden in extreme temperatures. Salt, corrosion and moisture resistant. Temperature range -60ºF to 1600ºF (-51°C to 871°C). Meets Mil Spec A-907."

According to the MSDS, that contains copper (same stuff from YHM page), so is it only good for stainless cans and baffles? I am using it for a YHM integral suppressed 10/22 which I believe is all stainless. Will have to take it apart and verify. |
