Took my new M15 out for a test run and this was the results. It has an 18 inch barrel 1:8 twist, I was shooting Factory Hornady 60gr bullets. Can the flash compensator cause this? I've already contacted the manufacture. I'm tempted to take it off and see how it shoots? I also put some 70 gr Barns TSX through it and it did the same thing. What do you guys think?

Either the bullet is hitting something or it's flying apart. But since the twist shouldn't be fast enough to cause the bullets to spin apart, I'm thinking the flash hider is causing it or the barrel is rough enough to tear the bullet apart.
Got to be the flash hider...I think....but do look down the barrel.
Barnes TSX are disintegrating? That is very strange. I would not shoot it again send it back to the manufacturer or have a gunsmith check it out. A smith should have rods they can check muzzle device clearance and bore scope the barrel.
Wowza! I would contact the manufacturer, as I would say it's a machining issue with barrel or flash hider. Perhaps in the threads. Could be something as horrible as bore and chamber centering issue. The flash hider would be the first place I would look. Should see contact wear if it is off center with bore. Otherwise it could be the bore diameter too tight and it is peeling off the bullet jackets.
Thanks for everyone's thoughts. I took off the flash compensator and sure enough I can clearly see where it's been touched by the rounds.. I'm still going to take this up with Armalite and at least have them send me a new compensator or I might just get something different on my own.. I'm taking it back to the range tomorrow just to make sure.
