military weapons are designed with lack of cleaning and maintenance in mind. virtually every SUCCESSFUL small arm designed for the military has succeeded because of that factor alone. when the cleaning issues were overcome, the M16 became a stalwart in the field of small arms.
a good example of a failure, though, was the Chechault (sp?) MG of WW1...way too easily jammed due to the magazine design with the mud and conditions of the WW1 trenches to operate.
when you have two dissimilar metals in a surface-to-surface contact situation, it's much better to maintain a clean/properly lubed surface to minimize any reaction; such as galling.
clean, de-burr and lightly lube... the pins should operate OK.
it is better to remain silent and be thought as being a fool, than to open your mouth and remove all doubt...
