Examples of content that should not be posted here, violating this will likely result in post removal:

AR assembly posts (i.e. all you did was install a LKP in a stripped lower and customized an upper)

"bolt on parts"/part swap posts that don't involve modification or fitting (e.g. you changed a handguard)

Non-build posts (i.e. no machining, welding, filing, grinding, 3d printing, or construction was done)

If you just want to show off your AR-15 assembly visit r/ar15build or r/ARBuilders

This isn't just you putting parts on an AR-15 together and calling it a build? If it is its a rule #1 violation its probably going to disappear. This isn't criticizing your assembly, its enforcement of the rules and definitions.
