Cracked M14 flash hider. Accuracy loss?

[ETCss Phil McCrackin]

I’ve got one for you M1A/M14 gurus… I recently discovered that the flash hider on my match M14 was cracked. How much accuracy loss am I looking at until I get this replaced? 600 yard line loss especially.

A cracked Flash Supressor can definitely affect accuracy. I can't quantify it off the top of my head, but I've seen off call shots at 200, 300 AND 600 yards traced to a cracked FS. Typically what I see happening is they will gas cut at the ends of the slots. The gas cutting creates a point in the slot which seems to eventually result in a crack. I'll see if I can post some pics.

It's definitely a "check periodically" item in the long maintainance list for the M14/M1A.
