I have the silent capture spring on my lilja build.....I really can't tell any difference with or without it.....but I have a surefire brake and adjustable SLR gas block....and the grendel doesn't recoil that hard to begin with.......BUT...after using an adjustable block.....I can't go back to a standard one. All my guns have em now.the brake with the gas block made the most difference.
The jb captured spring g comes alittle too light out of the box and I have to turn the adjustment in more on the block...i would have to get the different spring options to make itwork on my setup if I didn't have the adjustable block. I'm not totally convinced the captured spring makes that much of a difference to warrant the price
Granted mine is a mid gas...u may not need an adjustable gas block on a rifle length..just have a H2 or h3 buffer handy when u test fire.
Besides some recoil benefit.the adjustable block allows more control over th gas when shooting with a suppressor, easier on the brass,better compenant longevity
