JP AR-10 Heavy SCS Silent Captured Recoil Spring, Heavy Mass (H2) Version, Gen 2

GEN 2 Silent Captured Spring (patented) for AR-10-type rifles
H2 Buffer Version
Includes spacer to allow for installation in both carbine- and rifle-length buffer tubes.

Recommended Use:
Short-barreled rifles (SBRs)
Suppressed weapons
Rifles recommended to use an H2 buffer
Select-fire rifles
Piston-operated rifles

GEN 2 SCS Improvements:
New aluminum guide rod cuts overall weight
Heavier masses translate to more buffering mass and 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 buffers allow conversion between AR-15 and AR-10 models (and vice versa)
