I like my Hakim, fun gun. I sure as heck wouldn't have wanted to tote that artillery piece in battle, though.
Thing's gotta weigh 11 lbs. But, with its bayonet, you could reach across the Suez canal to stab someone.
Thing is LONG. I like it because I can take it to the range when someone else is there and they've be all freaked out by it, ask all kinds of questions about it, want to shoot it.
It is odd, if nothing else, and it only cost me 80 bucks in NRA very good/excellent condition. I bought the bayonet later. I've fired probably 500 rounds of assorted surplus ammo through it without incident. Don't know where this "blowing up" thing came from. Mine's been reliable. I only bought it for a curio, though, not anything to get excited about.
I know nothing of the FN49. As for actually using for something, I'll take my Remington M7, thanks. I don't really get excited about milsurp except as a collectable and the Hakim is collectable if only because of its oddity. Wish I'd gotten one of those $180 Rashids at the time when they were available.
