    I haven’t purchase a suppressor YET, but these O-rings really seal the thread protectors onto the threaded barrels. I gave one to a friend, who refuses to tighten his thread protector with a tool, even covered with a cloth. He learned that while using the O-ring, he can hand tighten only and his protector stays on during on all day shoot at the range.

    Bought a SilencerCo threaded barrel for my Glock. However, the thread protector kept coming undone. Bought these, and that completely fixed the issue. Would recommend.

    I basically just wanted to give a quick review and comment you guys on your hilarious emails and all your Communications even down to the little packing slip that comes with whatever you order is it’s funny too. The O-ring seem to be of good strength and precise size I’ll find out after using them how they hold up but I think that’ll work just fine.

    Super easy to install. Thread protector is no longer vibrating loose.

    Item works great, keeps the thread protector from backing out and getting lost.

    I have blacklist barrels in three of my glocks. Have no complaints. Excellent quality at a fair price. Packaging is really nice as well.
