Ok, I am EMBARRASHED to ask a newbie question. But, I really do need to know, so please help me.

I know this question is in the FAQ, but the FAQ does not have a photo for me to compare.

Is this normal wear along the cam pin cutout ? This is actually along the rail surface. My quess is that the leading edge of the carrier (bearing surface of the carrier) is scrapping the reciever in this spot.

Is this the normal wear that is referenced in the FAQ I "Wear inside upper at cam pin clearance cut" ?

ETA - The is a new reciever that has fired only 75 rounds. The carrier is a new Bushmaster carrier.

May be the gas tube lifting the carrier slightly.

Tweak, thanks for the heads up! I'll order a new gas tube shortly. the test passed fine during the last range session. another 1k down range with no issues to report.
