Archived [ARCHIVED THREAD] - Is this wear inside the upper receiver at cam pin clearance cut normal?
Posted: 5/7/2008 6:55:55 PM EDT
Colt 7.62 x 39 flat top upper, approx. 250 rounds since new.  Is this wear within reason, or too much?  I just bought the upper, and cycled the bolt a few times.  Took apart and noticed a small hair-thin 3mm long metal shaving.  I have since gone overboard with Militec-1.  Have not fired the upper myself yet as I am concerned of damaging this upper.

Thanks.

All the colts, bushmasters, and my Sabre do it as well. Normal
