AK-107 is a counter reciprocating balance rod, more of an engineer's experiment in recoil reduction.
Constant recoil involves continued spring compression with more rearward travel of the bolt carrier, so that there is no impact or over-sprung feel to the action, like an AR15 (buffer pad impacts), or an AK (over-gassed and sprung hard, with short bolt travel).
With constant recoil, the automatic mode of fire is pleasantly smooth, and requires no real training for a soldier to use. Amateurs can easily learn to pull off 2rd bursts within a few tries, since the cyclic rate is so much slower with constant recoil. Seasoned soldiers can be quite deadly with it.
The Ultimax100 LMG also used this principle, and is born from Jim Sullivan, who worked with Stoner on the AR15 and Stoner 63.
