Anybody played with the e-brake and/or the flash hider endcaps. I see where they say the e-brake helps with felt recoil and added dB reduction. This is mostly going to rest on a 10.5” 300AAC build that will be in a HD roll by the bedside and the reason for the K is to be as small as possible so not sure how necessary the e-brake is but if it makes enough of a difference I’ll buy it for trips to the range. And if the flash hider endcap actually helps then I might add it for the bedside roll, just not sure any of it is worth it in the end.
