Something I hadn't given much thought to until I read about how some handgun designs having problems with parts of different types of metal. Apparently different metals against each other cause electrolysis/corrosion & or can gall when they must slide against each other.
When building an AR there are myriad of parts, metals, & coatings to choose from. For instance, is it a good idea to match a SS gas block to a melonite coated barrel? Or how about putting a SS extension on a chome-moly barrel? Is that a big no-no?
TIA for any advice or comments...
