If I could only have one long gun I would have my AK47. Why?...Reliable, durable, good size round going down range, good ammo availability, you can pour dirt down barrel and it will still shoot.
same thing happened to me todayI concur on the 7.62x39 round and the AK. Versatile and reliable and available. Although I lost all my guns in Lake Michigan last week on a fishing trip.
Gonna have to go with some sort of shotgun.
Like stated above, you can hunt basically anything, they're great for self defense, and you can pick up ammo for them damn near anywhere.
If you could only have one longarm what would it be and why
