kind of like the piccatiny (sp?) rails that are on three sides of the front lower handguard? That way you could slide the grip on left or right or bottom. Plus you could put some type of bracket on the pistol grip so that the original grip could be used. I saw a pic somewhere on one of the forums (could've been here but I think it was roderus - not sure though) of a homemade three rail setup. If I can locate the pic I'll post it here.Cephus said:
