Only 1 Gun; What Do You Choose?
If you could only take one gun with you due to time, space(capacity), mobility, ammo. constraints, what would it be? You are going to have to cross wide open spaces, forested areas, semi-urban, and heavily urban areas. If you have a family, take that into consideration.
The S*** Has Hit The Fan(for whatever reason) and you have to get to coordinates that require you to(eventually) cross all these types of terrain. The general population must be considered potentially dangerous because they may want what you have.
You will have to spend nights in areas ranging from the forest to urban. Any and all situations have the potential to arise. You may stay in a barn one night, an apartment building in the city the next, and in a forest the next. Potentially deadly confrontations may occur in any one of these locations.
It may seem farfetched, but there could be develpoments that make any one of us have to bug out. Think EMP strike, Jihadists infected with genetically altered small pox(if you think this is B.S. read the scholarly book "GERMS,")(they want their 72 virgins) or multiple simultaneous terror attacks that cause panic, terror, and upheaval in the gen. pop.
1. Who would the manufacturer of your gun of choice be?
2. What model would it be?
3. What ammo. would you take?(if you had a choice)
4. Which mags would you choose?(can't take it all)
5. What spare parts do you take?(Be reasonable)
My vote, a Colt 6933(SBR) and M193 ammo. I'll compromise on heavier bullet weights. PMags. BCG.(Colt) CLP for lube/cleaning.
Hungarian SA 85 M in 7.62x39
A AK under folder, easy to carry concealed under a jacket. Your enemies will think you are unarmed until it is to late for them. It also can fire thousands of rounds with out extra lube or cleaning.
