This came on a Tac-Sol X-Ring receiver I purchased awhile ago. Great trigger, but I’m running a Kidd 2-stage instead. The prior (original) owner ground down the rear tang a bit to make it fit a stock he was using. It doesn’t look great, but still fits fine into my X22 stock without issue. Once you install it, you’ll never know, and it breaks nice and clean with a solid reset. I feel that the price of $180 shipped Priority reflects an appropriate discount for the garage gunsmithing work.
Any questions, just ask. No trades please. Thanks!
