A good walkthrough of the external and internal features of the new VFC AV74M AKM gas blowback rifle done by Jeidanten. This GBBR features a tough full-steel construction with stamped steel parts, giving it a rigid and durable build. The external dimensions and markings are highly accurate, allowing for the use of real AK furniture and accessories. Internally, the AV-74M also features a CNC machined steel bolt carrier, simulated bolt, and long-stroke piston assembly, ensuring durability and robustness. The adjustable bolt travel setting allows for both long-stroke and short-stroke operation, while the fire control group is made of full steel and features a realistic braided wire hammer spring. The gun also comes with a fully adjustable hop-up unit and a new 5.45x39-style AK gas magazine with a 107cc gas capacity.
