Thanks for the link. I love Jerry!
It is however not a prototype in his hand but a model1 FN CAL with the first genaration 20rd mags. The mags were replaced soon with an other follower. Nice piece they have.
This is a real handmade prototype. I have 2 different version of'm.
These are no longer FN CAL and not yet FNC
The upper two are proto's, the lower is an early FNC serial00xx
