Has anyone been able to loosen up the over travel and sear adjust screws which seem to be glued. I can get the allen wrench in the holes but, seems to have a very tight glue on the threads. The internal weight of pull screw was not glued which was the only way I could bring my trigger anywhere close, to Remington's 3.5lb from the factory claims. I thought maybe heat could be applied to the glued screws but, wasn't sure if there were any plastic parts inside or not. Thanks!
