概述巴西自行设计的FA03型LAPA5.56毫米突击步枪由于采用流行的无托结构,引起军界的注意。这支枪是1978年底开始设计的,一年后,制造出样枪。由于不希望缩短枪管长致使降低弹道性能,而要尽量使枪紧凑,FA03型采用了无托结构。于是将扳机移向前方,击发机构及弹匣装在枪托中空里。 FA03型的机匣基本上是由耐碰撞的塑料制成的,外形尤为精巧,便于操作和携行。设计良好的直线结构使步枪抢托底钣着地后能使枪竖起来。翻转式的表尺有两个觇视孔,分别为200或400米,表尺装在类似于AR10的提把
Overview Brazil designed FA03 LAPA 5.56 mm assault rifle due to the popular undelivered structure, causing military attention. The gun was designed at the end of 1978, a year later, to create a sample gun. Since it is not desirable to shorten the barrel length resulting in reduced ballistic performance, and to make the gun compact as possible, the FA03 uses a no-support structure. So move the trigger to the front, firing mechanism and magazine installed in the hollow in the butt. FA03-type casing is basically made of impact-resistant plastic, the shape is particularly delicate, easy to operate and carry. Well-designed straight-line structure so that the rifle grab the end of the board after landing the gun can make the gun up.
