Alright guys, you know the HK foregrip used on the PDW right? It is of the smaller size, and has a small guard in front for the upper fingers. This handguard is only available for the MP5 from what I have found so far, but I am looking for a replica type which could mount on a picatinny rail. I'm doing sort of a replica and that little finger guard it has is the main piece which gives it that look. Here's a good photo only on an airsoft gun: Any ideas what I could do here? Thanks!
