JP AR-10 Heavy (H3) SCS

H3 Buffer Version

Weight: 7.4 oz.

Recommended Use
The use case for an H3 SCS is virtually the same as the H2. In almost all cases, the two can be used interchangeably, and the choice between the two comes down to a preference in weight and cycling feel. The H2 is will produce a faster, snappier cycle compared to the H3, which will have a slower, heavier cycle. Only in extreme cases such as a severely over-gassed rifle without an adjustable gas block would the H3 be a functional recommendation over the H2.

Similar to the H2, this H3 model will function well in:

Short-barreled rifles (SBRs)
Suppressed weapons
Rifles recommended to use an H3 buffer
Select-fire rifles
Piston-operated rifles
