Will tango down rail covers fit the First samco M44 hadgaurds? I guess I should have asked this before I ordered both, but now I have the covers and the gaurds are on there way. Also does anyone make rile legth rail covers ? I  just realized that the covers that I got are only 6 inch long. Should I just get two more and trim them to fill in the extra space or is there another option?

Magpull may make rifle length panels not sure.. I also hear they are a bit flimsy.  If you want or need to cover the entire rail, yes trim another TD panel and mount the latches at either end of the rail.  I've seen it done where they butt against each other forming a continuous panel look(if trimmed in the proper spot), but I just trimmed mine  to get it close. no big deal.  and they're only 11 bucks or so.

good luck
