Barrel thread ID

[Junglepeanut]

I was digging through my bags o barrels and found this Boomstick with threads i dont recognize. Looked at some thread guides but didnt see it. Any help would be appreciated

O weird, at first I thought angel but that o ring on the ledge I don't think is right

I always thought it was Angel thread as well (but dont own Angels to try it on). I have a ton of barrels and assumed before the oring had just rolled down from the top but noticed it was in that groove. I dont habe anything else like it

Try it on an ICD marker.

Try it on an ICD marker.

I will have to see if i have a Cat left anywhere. Not sure i do

[Junglepeanut]

From looking at some pics i believe you may be correct though

Angel on left, ICD on right.

Definitely ICD. I can recognize a quad-lead thread from across the room.

Doc.

If no one else has already asked, I'd be interested in it.

I was thinking about hanging on to it for now but if i decide to sell i will contact you first

Thanks! I prefer the oring version of ICD barrels, keeps them from loosening up during use. And I kind of want to get Boomsticks for everything in my collection (at least for the ones with removable barrels).
