Like A Moth To A Candle

Apex has Yugo M70B parts kits, with US barrels for $310.

NoDak has (periodically) Yugo receivers for $115.

Being a monkey-curious DIY type... this is the oooooh, shiniest of shinies!

Need a semi-auto trigger set too...

And I'd need to learn how to do rivets.

This is a lot more involved than doing an AR.
