[Glock Glockler]

I don't know much about these rifles but I've heard they're a bit of a departure from the normal AK series, specifically that they have an internal balance mechanism that negates the recoil impulse, or at least diminishes it tremendously.

Anyone know the skinny on these?

WISDOM (http://club.guns.ru/eng/ak107.html)

The principles of operation of the AK-107/108 weapons are based on the utilization of energy of propellant combustion gases diverted from the barrel into the gas chamber through the side opening in the barrel. In order to reduce negative effect of the shock of bolt carrier in its front and rear positions, the carrier features a connecting rod in the form of a perforated lower rail. The latter is synchronized with the upper rail by means of a six-tooth sprocket. When a round is fired and the gas escapes into the gas cylinder to activate the two pistons of the upper rail and that of bolt carrier, the bolt carrier rolls into its rear position while the upper rail travels into its front position. The two dead points are reached by two inertia masses simultaneously, thus reducing recoil shock thanks to the synchronizing effect of the sprocket.
