Mods; If this is redundant, or ill advised, please feel free to delete or edit as desired.
This thread was inspired by several posts in another in which it was discussed that it would be nice to have information regarding the condition of various branded forged uppers prior to, and following the lapping procedure. The purpose is to help identify potentially troublesome as well as generally high quality brands of upper receivers for use in building quality at a good value, as well as to track this quality. There are other threads for commentary, so please keep any posts as concise as possible in order to keep this thread open for reference and quick perusal by interested parties.
If you have lapped a forged upper receiver, please post the following information:
Brand and style of receiver, finish, and how aquired - I.E. Anderson, BCA, BCM, PSA, Side charge, Standard, Anodized, Cerakoted, Painted, stripped/assembled, etc...
Picture of receiver face (if taken) prior to lapping
Any measurements, data, or perceptions of condition of receiver prior to lapping I.E. Measured tunnel diameter, oal receiver length, thread condition, finish conditions, etc...
Picture of receiver face (again, if taken) after lapping
Any measurements etc... after lapping I.E. - Anything that changed from the above information, impressions of the finish or receiver condition after procedure, etc...
A concise report of the tools, procedure, and experience of the process. (keep this short, list the tools, say what you did, give quick report of your perception of the upper before and after.)
This thread is not intended to be a bashing board on which to post your disgust or annoyance about any particular brand. Please keep posts focused on the perceived quality of the receiver, leave the ranting to another thread.
Thanks for the information folks, please add-to as you have experience.
