Sig did what they thought was right to use hinge points, where they failed is they had the factory glue them in. You would think anyone droping this kind of jing for this ARF would have a firm grasp in hinge installation, allowing the owner to do his thing the way he wants, why did'nt they just leave them un-glued, crips, c/a hinges would be prefered over too tight points, easier to change over!
