I actually have the adapter that is likely threaded for...it uses a special magazine made of zytel, and is very similar to what you would get with a Marcus mag adapter, but used these special mags, and required brutalizing your gun to attach it. I recall in recent years seeing the mags available somewhere...and they pop up on eBay occasionally...but if I can find it, and you can find a mag it's all yours.
Thanks a lot for the offer. I'm not interested in adapting it for ak mags, though. However, if you find the adapter, would you post some photos of it?
I'm curious to see if it's the same one I saw at the show last weekend. I'm pretty sure I've seen one like it over the years. Tried to find photos of one like it on line but gave up after 45 minutes of googling.
Compared with the photo receiver hole that GM posted above, the hole on my carbine is really rough, and bare, un blued metal...which would seem to suggest that bubba did it. I'm ok with that.
As long as it's not missing some kind of locking screw that keeps the barrel seated, I think I can proceed with the Accumounts PU conversion.
Anyone else have a /6616\ (or is it 6166?) with similar large numbered pair?
