A friend of mine bought a 700 Remington in .223 at my recomendation. I shot it and cleaned it several times for him. The triger was very heavy to my liking so I recomended he get a triger job done before we shoot it any more. He took it to get a triger job and the guy returned it and said there was nothing he could do for it. If I understand right it has screws that can not be adjusted. Anyone know what this is all about? The triger pull scale said the triger was pulling over 5 1/2 lbs. I thought all 700 Remingtons had adjustable trigers. Can this triger be replaced with a aftermarket triger?
