Just don't - Atrius Development Forced Reset Selector

Using the Recommended FTG. This does not work. The reason is both simple and stupid. Intalled as recommended I never had the trigger pass a funtions test. Installed without the spring and it passes functions test. Grind on your FTG on every side if you like. But this item is purely a $200 novelty gimmick where a spring prevents action. Or grind on the trigger group until you negate the spring wire with and somehow stop the spring from invading the channels meant for the trigger walls. Just dont buy this unkess you like a lot of precision work, grinding, fitting, testing, tearing down and repeating the install and tear down to keep functions testing that may never come. Then eventually cut through or smash the selector spring until not longer servicable.
