I've been searching for a stripped Sig 550 or 551 upper receiver for some time. If you have one for sale or know where I can acquire one, including the CCF imported versions, please contact me at Xzero AT aol.com. I would also be interested in a complete, original 550 or 551 if the price is right and the seller is willing to consider partial trades. Thanks.
