The gun participated in the Russian Army's Project Abakan assault rifle trials.[1][2] Nikonov's AS[M] and Stechkin's design were the only two truly innovative designs in the Abakan competition that made it to the final testing round; all other 6 competitors that made it that far were based on more conventional designs. Stechkin's design could fire two-round bursts at 2000 rpm or sustained fire at 600 rpm.[3] Stechkin's gun was slightly more accurate than Nikonov's, but turned out less reliable, mainly because it accumulated more fouling. Nikonov's design won and became the AN-94.[3] In TKB-0146, switching from one-round semi-automatic to fully automatic fire was accomplished by a secondary trigger located behind the main trigger. Squeezing the main trigger slightly, fired off a single round. Pulling it back fully, so that it pressed the secondary trigger, enabled fully automatic fire. Switching to the two-round burst mode was done by operating a different lever.[4][3] Two exemplars can be seen in the Tula arms museum; one of these is an early prototype that was configured for three-round bursts rather than two, which was the option for the later models.[5] See also
