I have a manners stock on my rifle for NRL22 and the balance point is right on the magazine well, but I would like to move it a few inches forward where it balance over a bag on a barricade. Any ideas on how to add weight to the front? I already have a arca rail installed but I’m not afraid to modify the stock further. Maybe a clever way to add weights like you see on mlok chassis. Open to other ideas as well. Thanks.
