Assembling a firearm requires precision and attention to detail. Each component must be carefully fitted and secured to ensure proper functionality. Understanding the order of assembly and the role of each piece is essential for building a reliable weapon.

Step 1: Installing the Trigger Mechanism

The first step in the assembly process involves installing the trigger mechanism. Begin by carefully inserting the trigger into the housing, ensuring that it fits properly within the designated area. Once in place, secure the control group components such as the safety switch and hammer. This setup controls the firing action and must be properly aligned to function correctly.

Step 2: Assembling the Buffer System and Stock

Next, the buffer system must be installed. Start by attaching the buffer tube to the main structure, ensuring a tight and secure fit. Then, insert the buffer spring and buffer into the tube, making sure they are aligned correctly for smooth cycling. Finally, attach the stock assembly to the buffer tube, providing support and stability for accurate handling of the firearm.
