WTB found some

You may want to say for which caliber.

I'm fairly sure all the M76 models were 5.56/.223. I have a couple of mags that were Galil mags modified to work that I can sell for cheap to get you going. And I am hoarding eleven M76 OEM mags (a couple in sealed plastic), most never used. I hadn't considered parting with any but when a fellow Hide member is in need someone must respond. I'm researching values (and I'm shocked). PM me if you're interested. In the meantime this will bump you to the top for a ride down again. Good luck.

Gawd, I owned and subsequently sold a Galil in .308W and a Valmet M78…….

Sigh, if only I had life to do over again. Shit, I think I had maybe $1K invested in each.

And, I could have bought a beater, late 50’s Mercedes SL300 Gullwing for $7K in about 1974…….

They made them in 7.62x39, but when they were imported, it wasn't a popular caliber because ammo was hard to get and expensive. So, there were less of those imported. I've had couple of them in 223, but magazines avalablity was the biggest drawback. When I saw one in 7.62x39 for $1200 wish I would have bought it, as I've seen them go for $8K + now if you're lucky to see one for sale.
