Because I'm cheap and like to fiddle with stuff...LOL. Typically in the end, it ends up being a very expensive and labour intensive way to go about things
The WE SCAR NPAS system seems like it would work...although I'm not sure how well it'll hold it setting with sustained usage.
Until I see and get a chance to compare the SCAR nozzle and the M4A1 nozzle...I don't want to shell out for something that might not fit.
