NOTE- The Nickel Boron coating is well known for reducing friction because of its molecular structure, it offers great heat dissipation properties, reduces wear on the BCG and the corresponding parts, and it increases the longevity of the BCG. Nickel Boron coatings are also known to reduce problems with function due to the decrease in overall friction and wear.
