Sorry, but you can't simply explain this away as poor tools. If you are going to sell a gun that requires a tool to take down, and you supply a tool SPECIFICALLY for doing that, then that tool should be able to do the job. If it had worked in my case I wouldn't even be turning to other tools. But it didn't. I clamped the supplied hex wrench in vice grips and torqued the screw until the hex wrench broke. Snapped. Again, if the manufacturer supplies a tool to do a specific job, it's not unreasonable to expect that tool to perform the intended job.
