Get an AK47 , I say is the best rifle . Is not the most accurate rifle but with minimmum of mentenance it will fire in anny condition , it doesn't jam and your grandchildren will fire it too.
In Romania untill a few years it was mandatory for every man to go to the army . The Ak is the rifle of use ,and as you can imagine every 6 months or 1 year a new man puts his hands on an AK , the same AK used for 20 or 30 years .
