Maybe a better question would be, does the 3 rail kit that Sig sells for the 551 hand guards work okay on the 550s?
The three rail kit screws into holes in the swiss guards, the guards have sockets for the nuts. If your cut down guards have the holes down to the rear on the bottom, I'd think the bottom rail would fit.
