I was curious, have you tried using any of the lighter Wolff sear springs with these or only factory originals?
I was wondering if it would make any significant difference in the ease of pushing the button. It looks easy enough in the video, but that finger is the one finger I have arthritis in....and the shooter in the video could be a classical pianist in his spare time.
I was also a little curious about whether these work fine on milled and stamped triggers alike. The only time I messed with an alternate mag release was during development, and I got stuck discovering mine only worked with milled...which wasn't the intended trigger for me. In both cases where I might want to get one of these, they are stamped groups.
The nice thing about these, is they are less than half the cost of two of those cool new Archangel mags with the built in release....and this works with mags I already have....not those huge 40 round things they only offer that release on...for now. The mechanics of changing mags with your release is better than an AK style anyway.
