GENERAL CONSTRUCTION AND OPERATION

The AK-47MAK-90 is a semi-automatic or self-loading, magazine fed repeating rifle. Gas pressure generated by the fired cartridge is utilized to drive the rifle’s gas piston system to automatically effect spent case ejection, recocking of hammer/trigger mechanism, and the loading of a fresh round from the magazine to the barrel chamber. A single shot will be fired with each pull of the trigger, until both magazine and chamber are empty. The trigger must be fully released forward before it can be pulled again to fire a succeeding shot.
Solid steel construction is used throughout for the operating components, with the exception of the stocks, which are either wood or high strength, heat resistant synthetic material.
WARNING: Before firing this rifle, be absolutely certain there are no obstructions in the barrel bore and chamber, such as grease, mud, snow or cleaning patches, etc. Also check your ammunition to determine that it is in good condition and that it is the correct caliber and specific type of commercial manufacture intended for this gun. The proper caliber description is tamped on the left receiver wall of the rifle) is 7.62x 39mm centerfire.
MANUAL SAFETY OPERATION

This rifle is equipped with a manually operated safety device in the form of a long pivoted lever located on the right hand side of the receiver. When set in the upper "safe" position a letter S on the receiver is visible just forward of the tip of the lever. In this safety position the trigger is blocked from being pulled to release the hammer and fire the rifle. In addition, it serves two other functions when "on safe"; it prevents foreign matter from entering the mechanism through the bolt handle slot in the receiver cover and also prevents the handle being pulled far enough to the rear to pick up and feed a round from a loaded magazine into the empty barrel chamber.

To set to "fire" position, the lever must be pushed downward with the thumb until it clicks to a stop. Again, a letter indicating that the safety is in "fire" mode will be visible just forward of the lever tip. The trigger may now be pulled to fire the rifle as described previously. CAUTION: Unless you are actually firing or plan to do so immediately, the safety lever should be kept in "on safe" position regardless of whether the rifle is loaded or unloaded.
