I have a similar rifle with a Benchmark 3 groove ss barrel and laminate stock with a Sightron SIII 6-24x50 FFP MOA scope. Martin makes top notch products.
I live in the town of Manati which is about a half hours drive from San Juan and regularly hunt iguanas. My gun of choice is an Edgun Matador standard R3M 25cal bullpup with JSB Kings.
