The Shock Pad is redundant if there's a sling involved since the two don't stack per Arsenal 148
Yeah, but the sling only stacks with a foregrip, not with any other "underbarrel" recoil compensator, like the auto-adjusting weight. Shock Pad stacks with all of them.
Might just be a personal preference for the Shock Pad on my part.
"Recoil compensation from a folding stock, hip pad, rigid stock,
shock pad, or sling are not cumulative with each other." Arsenal 148, emphasis mine. Now I do suppose that if I am taking RC from the Auto weight, and not the sling, then the Shock pad comes back into play, which makes for some excellent RC
That gets you enough recoil compensation to fire a short burst and a long burst: 1 magic, 3 gas-vent, 1 stock, 1 personalized grip, 2 auto-adjusting weight.
RC 8 is excellent for this except the Punisher can't fire Short bursts without modification, which admittedly is cheap, but uses up the last slot in the gun which I'd rather have for skinlink
I'd more likely just use a take aim action, to offset the last uncomped point of recoil on a full burst or the sustain spell penalty
