I was thinking about this a month ago. Yahthe mounting was the thing that got me. Only thing I can think of right now is to carry some gun tape and tape it on is all I can think of right now. It'll hold all right. Not pretty but it'll work.
If you don't want to carry a roll of gun tape then I think some sportting/camping stores will sell 1-2ft of folded up gun tape for minimalists go light travelers. I do rememeber seeing on the news something about folding gun tape but that was last year. You know the old saying, you can fix almost anything with gun tape.
