Incidentally, although the gas block is purely AKM, the gas vent in the barrel did change to a 90-degree design to minimize bullet shearing (a problem with early Soviet AK-74s with 45-degree gas blocks). This means the Romanian PA md. 86 has a double-angle gas port, which makes it much harder to clean the gas vent.
The AKM's receiver is stamped from a smooth 1.0 mm (0.04 in) sheet of steel, compared with the AK-47 where the receiver was machined from a solid block of steel. A rear stock trunnion and forward barrel trunnion are fastened to the U-shaped receiver using rivets. The receiver housing also features a rigid tubular cross-section support that adds ...
The operating mechanism does not require a gas expansion chamber at the muzzle, as in the AKS-74U to ensure reliable functioning, but does use a specially designed muzzle brake. The AMD-65, along with the earlier AKM-63, have been largely replaced in Hungarian military service by the AK-63, a more traditional AKM copy with a lower manufacturing ...
The forward hand grip of the AK-63 also lacks the palm swells which characterize the Soviet AKM (and most AKM copies made in many other countries). It's also missing the stepped lightening cut on the bolt carrier and retains the relief ports on the gas tube. The wood on the AK-63, like that of the AKM-63, has a bright, laminated blond finish.
AK-47 barrel and its distinctive gas block with a horizontal row of gas relief ports. The rifle received a barrel with a chrome-lined bore and four right-hand grooves at a 240 mm (1 in 9.45 in) or 31.5 calibers rifling twist rate. The gas block contains a gas channel that is installed at a slanted angle with the bore axis.
It was derived from the AK-74 rifle, with modifications that mirror those made to the AKM to create the RPK. The RPK-74 also uses a longer and heavier chrome-plated barrel, which has a new gas block with a gas channel at a 90° angle to the bore axis, and a ring for the cleaning rod.
While the gas piston is sent rearward, the bolt, attached to the gas piston, is unlocked from the trunion and ejects the spent casing. When the bolt and gas piston reach the rearmost position of the receiver, the recoil spring pushes them forward again picking up a new round and chambers it, and the cycle repeats when the trigger is pulled.
They can be chambered in 5.45×39mm, 5.56×45mm NATO and 7.62×39mm, and use a barrel and gas system assembly and iron sights line similar to that of the AK-74M/AK-100 rifle family. Improvements added from the AK-12 include Picatinny rails , a new pistol grip, a new adjustable buttstock and a new flash hider. [ 14 ]
