柯尔特公司的新型导气系统这种新型导气系统的特征是仅挪动横向定位销就可简单地将活塞筒卸下,然后再卸下活塞组件,无需像其他枪型那样需要卸下上护木。该导气系统由柯尔特公司的设计师迈克·拉普兰特设计。其改进了传统的活塞筒与活塞设计,避免枪管受到过大的压力,从而提高了枪管寿命和射击精度。在这届展会上,除了柯尔特,还有HK等公司也展示了改进活塞筒与活塞的M16系列步枪。
Colt's New Air-Guide System The new air-guiding system features the ability to remove the piston cartridge simply by moving the cross-lock pin and then remove the piston assembly, eliminating the need to remove it as with other gun types Guard wood. The air guiding system was designed by Collaborative designer Mike Lapland. It improves the traditional design of the piston and piston to avoid excessive pressure on the barrel to improve barrel life and shooting accuracy. In this exhibition, in addition to Colt, HK and other companies have also demonstrated improvements to the piston cylinder and piston M16 series rifles.
