I've heard the 7400's called "jam-O-matics" and then I've heard they are really good. I've heard you have to keep the gas port clean, and also remove the front stock to lubricate (which doesn't concern me at all.) I have a chance to trade for one in 30-06 but I don't want a lemon. It's a couple of years old with a synthetic stock in nice condition. I think they are under $500 new. One good thing if they work well is that you can buy 10 round mags for them for everything but hunting. Does anyone know if they work well? How far off am I in my assessment, which comes from no real knowledge? Thanks!!
