Suppressive Fire - Delivers 100 Potency, 2s Stun at 5y's.
Head Graze - Delivers 100 Potency, 2s Silence at 25y's.

This may just be my opinion but it seems fairly silly to run up to 5ys of your target to "Lay down Suppressive fire". Secondly the name and effect to me don't seem like the best fit. Instead Head Graze, its recast sharing ability, sounds much more suited to being a stun and Suppressive fire should instead be silence.

TL;DR - Swap the names and make both 25y's.
