Michael,
Thanks for the response.
My experience as a Combat Vet and dealing with others, is that we enjoy using weapons and the calibre that we utilized while active. 7.62 Nato & the 5.56 Nato are favored by this group. During my "in & out of country" runs, I utilzed an AK when the need arose, but favored my M-14E2 when perched in my hide on hunting trips. Combat Vet's really don't like the Soviet round -- too many coming at one to appreciate.
The XGI in the 7.62 Nato would garner a following of returning Vets and old timers as well. It would be a profit center for Ruger to complete and if priced a couple of bills below a grand (keep in mind that the R&D was done previously), it would be a bonus to them and the civilian market. Offer the base model with a standard match barrel, a selection of easily added accessories, as well as the utilzation of M-14 mag, and you have a formula for an instant succe$$.
Being a gun dealer (no advertizements ever to follow), the young guns coming back want reliable toys to get ready for the Zombie Invasion.
Just some thoughts from this old-timer.
P.S.: Honor Vets this Wednesday - Say a prayer for them.
