Separate starting and ending delimiters allows the arbitrary nesting of quotation marks in strings to be used, allowing a fine degree of control of how and when macro expansion takes place in different parts of a string. Requested changes included an electronic round counter that records the number of shots fired, a heavier barrel, and possibly replacing the direct impingement system with a gas piston system.
Compact size Shortened barrel This is for a variety of reasons such as heat dissipation during full-auto, and accuracy as a byproduct of barrel weight.
