I've been thinking: what if I mounted an ics glm to an ics m16 ras. Well now I decided im going to do it. But before I begin purchasing parts and grenades, I have some questions like: Can I remove the stock on the glm? Where can I get a rail adapter so I can mount them together(also what is the terminology for rails and rail mounts)? One last thing how much does the glm weigh fully loaded? If anyone could help me out with this I would be much appreciative.
