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 the 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.<ref name="Deg"/> 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]].<ref name="Deg">Михаил Дегтярёв, "[http://www.kalashnikov.ru/upload/medialibrary/d29/10_16.pdf «Абакан» Стечкина]" (Stechkin's Abakan), ''Калашников.

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.<ref>{{cite web |url=http://wartime.org.ua/2808-fnalsti-konkursu-abakan.html |title=Фіналісти конкурсу «Абакан» » Військова панорама |accessdate=2013-07-05 |url-status=dead |archiveurl=https://web.archive.org/web/20140413110011/http://wartime.org.ua/2808-fnalsti-konkursu-abakan.html |archivedate=2014-04-13 }}</ref><ref name="Deg"/>

Two exemplarsexamples can be seen in the [[Tula, Russia|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.<ref>[http://www.arms-museum.tula.ru/exposition_new/11.html Оружие И.Я.
