I too run JP SCS's in both my 16" and 18" Grendels. The sproing feeling in the stock is one of the things I hate in the AR platform. Both rifles are midlength gas systems. I run the H1 equivalent in the 16" and an H2 equivalent in the 18". Ejection on the 16" is a perfect 4:00 to 4:30 while ejection on the 18" is more of a 3:30. Never ran supressed on either so can't comment on that. I'll never go back to a regular buffer again, for what it's worth.
