The JP Enterprises SCS-15 Builder Kit With Spring Pack is the perfect choice for use with short-barreled rifles, suppressed weapons, rifles recommended to use an H2/H3 buffer, select-fire rifles, and piston-operated rifles. These AR15 Lower Parts by the experts at JP Enterprises will not function with the Primary Weapon Systems direct impingement bolt carrier as the design will prevent the rifle from cycling. The JP Enterprises SCS-15 Builder Kit with Spring Pack includes partially assembled SCS unit, five alternative weight springs and spacer to allow for installation in both carbine-length and rifle-length buffer tubes so you have everything you need.
