why don't you get the 7600 Pump carbine? Its probably just as fast for a second shot and 100 quadgigazillion times more reliable...

once that jam master chamber gets a light coat of rust in it, you can never never ever ever get it completely smooth again (on a molecular level)....3 cents worth of hard chrome in the chamber or maybe even gasp NITRITED (the fire taught me that was good) and the rifle could be reasonable POS instead of a total POS.
