yes they make them for 7.62. got a flash hider for my scar17 from surefire the wife is using a muzzlebrake from surefire on her savage 308 ive also got their muzzlebrake on my bcm carbine.
ive used a lot of brakes and hiders, the surefire is the best ones out there.
the extra benefit is my surefire suppressor fits on three different guns.
if you cant find what you want call surefire directly they have great customer service. i ordered my scar17 hider over the phone since no one stocks it. it was no backorder everywhere on the net. called surefire and there was one in my mailbox 4 days later.
highly recomend a surefire.
