原文：

The GAU-5A features a quick-connector barrel and handguard assembly that attaches to the upper and lower receiver of the weapon. The new Aircrew Self Defense Weapon is based on the M4 Carbine, and weighs under seven pounds. It's designed to fit inside the seat survival kit of ACES 2 ejection seats. The M4 carbine also breaks down into two main components. Two pins disconnect the M4's upper receiver from the lower receiver and barrel assembly.

The GAU 5A's pistol grip is designed to fold back against the collapsible buttstock to save space when stowed. It also features folding front and rear iron sights, replacing the standard M16-style A-frame front sight.中譯：

GAU-5A式自動步槍具備槍管快拆功能，而且槍枝的上機匣與下機匣都附加了護手。

這款「空勤人員自衛武器」是依據M-4式卡賓槍改造的新式自動步槍，重量不到7磅，可收納在ACES 2型彈射座椅的座椅求生包內。

M-4式卡賓槍也能分解成兩大組件，僅靠兩根插梢就能將上、下機匣及槍管總成分解開來。

GAU-5A式自動步槍採用手槍式槍把設計，可以往後折疊靠向伸縮式槍托，以節省收納空間。它也具備準星與覘孔均可折疊的功能，取代了M16步槍標配的A形框準星座。
