The JP SCS does not increase nor decrease reliability in my experience, but there are others who claim the JP SCS is not as reliable as the standard buffer- spring and will never recommend them for a duty gun..I use JP SCS's on all of my hunting and competition AR rifles... The JP SCS does make charging the rifle much smoother and will improve recoil if you know how to set the gas port to the correct SCS recoil spring weight. No matter what Karl from DeRange claims, there is no need to worry about the mil spec recoil retaining detent breaking and jamming the rifle as long as the rifle is in spec. There should be a minimum of .030-.040 space between the buffer detent and the buffer when the rifle is closed..The buffer should never touch the buffer retaining detent until the upper is opened from the lower...
