How about the LMT L129 or KAC M110?
Maybe a GI (get it? German Issue, gun puns are the best) of the PTR GayDry clones?
That Fulton Armory M14 ESR gets my juices flowing.
Oh, heck, I can go on all night.
Write all the suggestions down, assign a card to each and then draw one out of a hat!
I would recomend the LMT over the knights because of price only. Also the lmt used some knights technology too
