I have an A1 complete upper with B/BC that I am considering selling. However, I am not sure what price I should ask. Of course, I would like to get the most I can for it, but I don't want to ask for too much and not get any responses.
Although the upper came from a preban colt lower, I am not certain of the manufacturer as it does not seem to have any markings. How would I verify the manufacturer? May there be markings under the handguard? What about the bolt and carrier?
Here is a pic of the upper. As you can see, it has a teardrop forward assist with no deflector. Full birdcage FS w/no bayo lug. The upper also has a triangular handguard cap. Thanks in advance for any help or insight.
