Hi Luis,
A company called Mil-art used to do a modern weapons pack, which included the M16 with grenade launcher, but I think they have ceased trading. Historex Agents still sell some of their stock, but not the weapons.

My 13 year old son is after one of these. We saw one on the Forge World stand at a Games Workshop conflict in Edinburgh. It looked very nice, but at £95/$180 he can buy it himself.

I haven't managed to get to Euro since 1999, I hope I can manage this year. I miss the Friday and Saturday night get together in the Clifton Hotel.
