あれ……?
日本語版wikiのイスパノ20mmの説明って随分前から
「ショートリコイルとロック解放時にガス圧作動という併用方式」
とか書いてあるけど、
英語wikiだと
The HS.404 was gas-operated. When the projectile passes a port cut into the barrel,
the hot gasses enters a chamber where it presses against a piston.
The piston is connected to a rod that unlocks the bolt, allowing pressure in the barrel to drive the bolt backward.
Since the bolt was locked during firing, the heavy bolt of the Oerlikon could be replaced by a much lighter one,
which greatly increased the rate of fire, about 200 rounds a minute over the Oerlikon.
となってて、
26の動作図見ても単なるガスオペで「ショートリコイル」なんてどこにもないような。
