Military Reisings are usually parkerized. They often have an adjustable front sight with an Allen screw and a rear sight with a retaining screw. They routinely have 14 fins on the barrel, a two piece magazine release, outward flanges on the safety/selector switch, sling swivels, stock ties (crossbolts through the forearm), and a knurled take-down screw. Finally, the military model commonly has a three-hole trigger guard, proofmarks like "PH" or "Pm2" above the chamber, and serial numbers ranging from 20,000 to 120,000.
