I know there are a lot of knowledgeable people out there and I am hoping one of you can help me identify this part.
Here’s what I know;
I found this stuffed in the bottom of a German military surplus AK-47 magazine pouch that I bought from The Sportsman’s Guide.
It was wrapped in brown paper and appears to be unused.
The flanged end diameter is just over ¾ inch diameter, I would guess about .780 inch.
The overall length is 15/16 (.94 inch).
The end with the smaller diameter hole is 3/16 (.19) Inside diameter. And the flanged end has semi-round notches around the circumference.
It is also threaded in this end. The threads appear to be about ½ diameter and are a fine pitch. I don’t have my thread gages at home, they are at work.
At first I thought it appears to possibly be a barrel nut for an AK barrel except that the ID is WAY too small to safely pass a 7.62 round through. I could dig my AK out of the back closet except that my wife has already gone to bed and I don’t want to disturb her since she has to work tomorrow.
After thinking a little more about it, if it does fit onto an AK barrel, could it be used to create backpressure to allow the gun to cycle properly using blanks? I think I have seen adapters for AR's that are used when shooting blanks. I know you would blow your barrel to bits if you tried to use this with real rounds.
