A "disabling bullet" hidden in the chamber (3 months ago) is going to be forgotten in the heat and stress and fear and ringing in the ears environement of sudden life or death combat. Then it will get the defender killed.

Indeed. There are already cable locks that work by passing through the bore or through a revolver's cylinder, but those are readily visible and you *know* the firearm is disabled. Better that than a device which makes the gun inert at the worst possible minute.

When the M-16 was earning its bad reputation in Vietnam, there were more than a few soldiers found laying dead next to their rifles, each with a cleaning rod stuffed down the barrel in a desperate attempt to unjam a stuck case. This contraption brings similar images to mind. Instant, complete vulnerability, right when you think you have the upper hand. Nice.

Correction on my first post on the Mini. My solution wasn't to accurize the Mini. It was to correct problems in the design so that the point of impact and the groups would remain at an acceptable level without the frustrations of changing impacts. I expect under three inch groups when I'm done with a cold to hot barrel. I don't expect 1 MOA.

You got it! (And I want the .89 cent Mini 14 accuriser too! Shooter can charge $20 for it and make a FORTUNE!)
