| Does the barrel I mount my Spectre to, have to be cut to SilencerCo's o-ring specs, or can it be used on a standard threading? The reason I ask, is I am having my 15-22 barrel cut and rethreaded, and I don't know if I should have it threaded to the SiCo specs. I do plan on adding another .22 suppressor at some point, and I don't know what brand, so I don't want to be committed to SiCo by having the barrel threaded like that. |

Quoted: Can someone explain this Spectre o-ring and spacing crap to me please, I have one on the way. It keeps the threads cleaner. The spacer that was mentioned a couple threads up is used on factory threaded barrels where the threads are to long. The SW 15-22 needs a spacer.

Quoted:
What happens with the crud if the end of the threads are not machined off to engage the o-ring? Will the shit build up on the end of the threads then cause problems when removing/reattaching the suppressor? If they're .400" long, they'll snug up right against the o-ring without pushing through it and possibly damaging it or causing an alignment issue. |

I can say from experience that having threads longer than .400" is bad with a rimfire can. Back in the day I was testing a CMMG 22lr 16" upper for them and put my old AAC Pilot on. The threads on the barrel were standard AR depth and I threaded the can all the way on. I'm assuming I caused an alignment issue as of course the other rifles and pistols I'd used that can on over the years had shorter threads so there was carbon buildup in the un-used thread portion. I'm guessing I had a baffle strike as the two rounds I fired hit the dirt about 10 yards in front of the rifle. Thankfully no damage to the can. After putting a couple peel washers on to take up the space it worked just fine.
Now that rifle is an SBR (ADCO chopped and has .400" threads) and the old AAC can went to Gemtech for the IOU conversion. To the OP, as others have said as long as your threads are .400" your Spectre will work fine. Great can by the way. I've got a pair of them. One usually rides on the above mentioned SBR. |
| Most threaded barrels I've seen are .400, or cut for the o-ring if there is an adapter attached, like on a pistol. The main issue came with 22lr AR barrels because they were threaded to AR15 specs, which was too long, thus requiring you use a spacer. Get a barrel with .400 and you'll be good as gold. Get one threaded with sico specs and you'll be platinum. The CMMG 22 barrel I bought was cut to sico specs. |

No, the Mask does not need a spacer as long as your threads are 0.6" or less. Quoted:

This spacer? https://www.store.silencerco.com/products/1-2x28-rifle-thread-spacer?variant=221756564 Does the Mask need this also? It doesn't need one, however Dead Air still recommends 0.4" threads for the best performance and longest baffle life. Posted Via AR15.Com Mobile |
