"Check out the big brain on FredP!"
Wow, that is the first time I've ever heard that one, I'm putting it in my bag O' tricks, thanks Fred.
As for that swap, keep the AK, save up a bit and get a good HP, they aren't that uncommon and as has been said a time or two, even in pristine condition can be found for less than $600.
AK's don't ring everyones bell, I understand that, but when TSHTF, which would you rather be armed with? I would prefer a respectable distance in that situation.
Keep checking the 'for sale' section, you'll find a much better HP sooner or later.
