New Army weapon tech could make cleaning obsolete

Army engineers at Picatinny Arsenal believe they’ve cracked the code to make it happen with a new surface applicant, which they said could go into production in 2018.

When rifles and machine guns are fired, byproducts accumulate, leading to what's known as "fouling." Buildup of powder residue and moisture can eventually cause the weapon to jam, or lose accuracy, reliability and cyclic rate (rounds per minute). That’s why soldiers have to clean their rifles, generally with a wet lubricant known as CLP (cleaner, lubricant and preservative).

The new material, known as durable solid lubricant, would be applied during manufacturing and coats the weapon's moving parts. DSL simply prevents material from sticking to the weapon's surface. Since the fouling buildup only loosely adheres to a DSL surface, any force from the other moving parts or vibrations from firing is enough to knock it loose and keep the rifle clean.
