The grenade consists of a heavy warhead section of 30–75 mm (1.2–3.0 in) in diameter for the nose, and a lightweight hollow tube for the tail section. The inner diameter of this tube is 22 mm, and fits over the tube attachment on the muzzle with only a small amount of play, to create a good gas seal and promote accuracy.
The original Soviet blade bayonet as standard to the SKS had to be replaced by a unique Yugoslav bayonet to accommodate the new mount placement. [7] A commercial variant of the M59 and M59/66 series, available for sale to civilians in some of the post-Yugoslav republics, lacked the bayonet or the ability to fire rifle grenades. [15]
The gas tube and upper handguard could now be removed as needed to access the gas port and piston for cleaning.

One principal advantage is that the moving parts are placed in-line with the bore axis meaning that sight picture is not ...

The vent-sealing tube accurately fits into a chamber formed at the end of the vent, and is held in place by the gun lock or some similar means. The force of the explosion expands the tube against the walls of its chamber, while the internal structure of the tube renders it gas-tight, preventing any escape of gas through the vent. [3]
