18" MLGS in 5.56, 6.5 Grendel, .224 Valkyrie, etc. is going to be a tough nut to crack suppressed.
The reason is that you already have a lot of excess plug dwell with MLGS and an 18" barrel.
By adding a suppressor, it's like adding more barrel length because of accumulation in the baffle array.
I know guys who have broken bolts using both adjustable gas blocks and adjustable gas carriers at the same time when shooting suppressed.
These are the same problems Crane had when developing the SPR, so they went with RLGS 18" with a reflex Ops Inc can to really tame down the cyclic rate as best as possible.
I personally would not suppress a MLGS 18" unless it has a flow through can, and I would still consider adjustable gas carrier with extra power recoil spring and heavier buffer.
Of all of my personal 18" MLGS Grendels, I haven't even entertained putting my brake attach devices on them for use with my suppressor.
I am looking at the LaRue Tranquilo flow-through suppressor though for them, but would still prefer to cut the barrel to 13.7", P&W the brake, and mount that way just to keep overall length down.
