Parkerizing or manganese phosphate is a durable, utilitarian finish for firearms that varies in tones of grey. Parkerizing is mainly seen on US Military firearms like the M1 Garand and the M1 Carbine.
We fully disassemble and sand blast all the metal parts taking care to protect vital areas such as the chamber and bore and not round over any edges. Then we degrease all the parts before submerging them in our parkerizing solution.
Parkerizing is also a great pre-treatment for Cerakote application giving you an even more durable finish and better adherence.
