JP AR-15 Heavy (H2) SCS Silent Captured Recoil Spring, Heavy Mass Version, Gen 2

GEN 2 Silent Captured Spring (patented) for AR-15-type rifles H2 Buffer Version (Heavy Mass) 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 Maintaining all the benefits of our polished buffer springs and proprietary LMOS™ buffer, this combination buffer-spring assembly eliminates the friction of standard buffer components resulting in outstanding smoothness and sound abatement. The AR-15 version fits and functions in any gas-operated AR-15 variant, regardless of caliber. 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 Interchangeable buffers allow conversion between AR-15 and AR-10 models (and vice versa)
