a smooth dust cover like the AK-47 and unlike the ribbed dust cover of the AKM. However, it utilizes the simpler dual "U"-shaped recoil spring guide of the AKM instead of the telescoping rod of the AK-47. Has a blued finish like the AK-47 and unlike the AKM, which has a black oxide finish or a parkerized finish. Like the AK-47, sights will only adjust to 800 metres, whereas AKM sights adjust to 1000 metres. It also retains the button on the right side. Nearly all Type 56's lack the side mount plate that was featured on many variations of the AK-47 and AKM. The gas relief ports are located on the gas tube like the AK-47, unlike the AKM which had the gas relief ports relocated forward to the gas block. The gas block is also like the AK-47 in that it has the forward sling loop (instead of the handguard) and a cleaning rod capture. The fixed stock of a Type 56 has a less in-line stock like the AK-47, opposed to the AKM which has a straighter stock. It, however, uses the AKM style single upper tang insert type attachment method and has the rear sling mount on the underside of the stock as opposed to the AK-47 dual tang type and receiver side sling mount. Its rear trunnion is also very similar to the AKM, though the distance between the rivets are different. Certain versions of the 56S/MAK-90 have an angled receiver back wall, though these are typically milled variants with a thumb hole stock. The underfolders have stamped stocks like the AKMS but only lock on the left and are angled downwards like the AKS-47. The stocks are also typically made out of thicker steel, thus have less reinforcing ribs and detents, and they also lack the pistol grip reinforcement plate and true rear trunnion of the AKMS, having a simple pseudo end-cap rear trunnion, likely due to the thicker receiver. Variants Type 56 – Basic variant introduced in 1956. A copy of the AK-47 with a fixed wooden stock and permanently attached spike bayonet. In the mid-1960s production switched from machined to stamped receivers, mimicking the improved (and cheaper) Russian AKM, while the permanently attached bayonet became optional. Still used by Chinese reserve and militia units. Type 56-I – Copy of the AKS, with an under-folding steel shoulder stock and the bayonet removed to
