A full mass carrier helps accomplish that, in conjunction with the optimum gas port size, action spring weight, and buffer weight.
If I was configuring a competition AR15 chambered in .223 Wylde with a RLGS or ILGS and I wanted my split times to come down, I would use the JP SCS with a JP Lo-Mass carrier and adjustable gas tuned to one or two specific loads for competition.
For 6.5 Grendel, I would feel better about a longer gas system length used in conjunction with a Low-Mass carrier and adjustable gas, but I would want adjustable gas on the carrier instead of up-front at the block. Right now, I'm unaware of any company making both a lightweight/lo-mass, adjustable gas carrier.
