Thanks for the feedback, everyone. I read through the comments and decided to take them seriously.

I've already issued a full refund to the buyer, and the files, download link, and assembly video have all been removed.

I underestimated how people would feel about charging for a non-functional dummy model, and that's on me. Rather than argue about it, I think removing it is the better decision.

Thanks to everyone who shared their thoughts.

Just uploaded my printable ACOG 6×48 dummy model

This model does not match the dimensions or internal construction of the real optic. As a result, real ACOG accessories (such as kill flashes, lens covers, etc.) are not compatible.

TEST #1

I'm still testing the receiver's strength, so I'm running the weakest buffer spring possible.

The cycling is reliable, so a new receiver is already printing.

Keeping the original structure while maintaining strength is challenging.

The size means I also have to carefully plan how to split the model for printing.

I'm developing the assembly method along the way as I build it.
