ao-27是实验性“武器- 箭形子弹弹药筒”综合体的一个部分。 该综合体于1960年开始在NII-61开发。 在此时，他们已经完成了多项研究，都在提高 AK-47突击步枪 从不稳定位置射击的有效性。

ao-27 自動系統採用氣動操作，通過槍管壁側面的開口排出火藥氣體。 所用的槍管是標準 7.62 毫米口徑 槍管毛坯，其中有標準輪廓的膛線，但更淺。 子彈的旋轉促使引導子彈沿槍管前進的托板的各個部分明顯分離。

The AO-27 is a Soviet select-fire, gas-operated assault rifle, Designed by D.I. Shiryaev in 1961. The assault rifle is chambered with an original 7.62/3 mm OPS flechette sabot round. Tests shown excellent flatness and penetration of the flechette sabot rounds, but also, a slightly lower accuracy, comparing with common rounds.

The AO-27 was a Soviet assault rifle, chambered for the 7.62 mm fin-stabilized flechette sabot round. The flechette itself had a body diameter of 3 mm.

2024年8月31日 · AO-27 - 10x54R OPS- The AO-27 was an experimental rifle chambered in 10x54R. It fired a flechette round from a modified 7.62x54r case which had had been under development at TSNIITOCHMASH since 1960.

2013年9月6日 · In the late fifties and early sixties in the USSR, designers Dvoryaninov and Shiryayev carried out work on subcaliber swept ammunition. In 1961, Shiryayev created an experimental machine gun AO-27 for these munitions. Tests showed a very good flatness of low-sized feathered bullets, but accuracy, somewhat inferior to conventional ammunition.

The AO-27 is a semi automatic, gas-operated 10x54mmR flechette rifle and AK derivative. The automatic device of a design of Shiryaev of joint-stock company-27 under оперенную подкалиберную bullet Дворянинова is tested in ВНИИточмаш.

工厂专门生产了一批弹药用于ao-27测试，测试的结果很好，自动射击时比ak-47和akm更容易掌握，子弹直线飞行距离约530米，比ak-47和akm高出约200米，这意味着它更利于瞄准，在1000米距离内弹道仍比较平直，同时子弹散布更小。
