well i really cant be bothered to keep arguing about this rifle anymore, we're never going to agree
and that first phrase wasnt even aimed at you TL
anyway, while that ar-7 is an interesting and compact design it does have some major drawbacks, being that it frequently jams, has a dodgy magazine release and a few other drawbacks, i researched it alot a while ago, it seemed like a great idea, but after looking around i bucked my ideas up
i'd much rather have a ruger 10/22 breakdown personally

whilst less compact its got a far better track record of reliability and accuracy.
and i do agree .22 is an excellent and useful round, not to mention exceptionally common and the easiest to get a fac for.
crossbows are also a consideration, although most lack the ability to be packed down to a reasonable size, and im more of a rifle/bow kinda guy, at the end of the day its all down to personal preference.
