I would "clamp on" one of them quality holosighted US-made AKs in kal. .223 to that tractor if I were you. You would not want to be undergunned when you catch one of them poachers matey.
Don't get one of them AR clones because if they fall in the mud they will no longer work!
PS. Get a tin or sealed plastic bag of SS109s for that Nevada made "AKSU" while you still can.
