My SR556 has about 400 rds through it. No "carrier tilt" just initially wore the finish off the tube lower 1/3 near the pin.
But I discovered a wear point in the receiver, where the charging handle tip rides. The area is about 1/4 " long (depth of wear = 1/64") just aft of a semi circular cut-out.....
I doubt the charge handle tip would have caused this....I'm thinking the cut-out is related to the BCG cam pin movement and the cam pin may be the culprit.....but not a mark on the cam pin.
Any thoughts would be appreciated. I hope the Iphone pix are clear...
