Lyman's "universal reciever"

[outoftowner]

Alright, reading through my lymans manual and I see that for most of the calibers they have the test rifle listed as "universal reciever". What does this thing look like? Does it just have interchangable bolt faces/barrels/chambers?

If so where do I get one

thats pretty neat. Wonder how much one of those buggers would go for.
