Heavier masses translate to more buffering mass and reduced chance of bolt bounce
Full correspondence between SCS masses and H1, H2 and H3 buffers
Additional mass added to both AR-10 and 9mm models for better, broader function
Interchangeable bumpers allow conversion between AR-15 and AR-10 models (and vice versa)
GEN 2 AR-15 Silent Captured Spring Builder with Alternative Spring Pack, H2 Buffer Version
Includes SCS unit, five alternative weight springs and spacer to allow for installation in both carbine- and rifle-length buffer tubes.
Short-barreled rifles (SBRs)
Rifles recommended to use an H2/H3 buffer
The JPSCS2-15 will not function with older Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling.
