Never seen one. Interesting because it's a 16ga/.22LR.

I saw that also, didnt Spain make Model 99s also?

Interesting.. based on 24, but not approved by Savage from what I can see.

And, yes.. Llama made Savage 99C's for 7 years or so in Spain under contract for Savage Arms. Also redid manufacturing for larger parts into investment casting and late 80's CNC machining.

The CARRERO Y ASTELARRA ATLAS COMBINATION rifle..
