I have had that tacsol release on my 10/22 for 2 or 3 years now and the accidental dump has yet to happen. FWIW, on my gun at least, you have to move that "lever" quite a distance before the mag releases. Also, my release has a bit of play in it too, while typically a negative, I think that in this case such also helps to mitigate the "AD." FWIW, the lever sits much closer to the trigger guard than that pic (understand that was not the purpose of the pic). The one negative that I have experienced with it is when I had the BC folding stock on as well and between the pistol grip and the release there was not much room for the first knuckle...other than that, I think it is a nice addition. Yeah, JJ, that is the "new" one, I have never used one of those to be able to compare with the tacsol.
