Stripping down the 750 seems rather easy a screw up front on the forarm gets you to the spring while the two pins on the receiver get you to the trigger mec.With my bar i always stripped it down about every 100 rounds . The main thing is not to over lube and i like to store with the muzzle down i was told to use the chamber brush as discribed by remington and was also told that synthectic oils will not gum up. I myself just use the Hoppes #9and have never had any problems .(used it on my BAR for three years with never a jam) Most problems with jamming is guys tend to over lube. Keep it dry. Later Tanoose
