i recently modified my auto bolt released plate by grinding down the small spike on it to allow my bolt to close without using the bolt release tab thats located by the safety. when i pull the bolt back and use the bolt tab to keep it open, i then pull back on the bolt and it slams shut without releasing the bolt tab thats by the safety. i also installed an extended magazine release that is admittedly pretty cheap plastic. the problem is that when my bolt is in the open position i will go to change magazines, but when i depress the extended magazine release the bolt will move foward slightly and when i go to pull back on the bolt it will not slam shut like the modification intends it to. in fact the bolt release tab by the safety is even harder to work with and the magazines will not click into place. if i buy a premium extended magazine release, (like a volquartsen) will it allow me to change magazines with the bolt open and then close the bolt by just pulling back on it while still accepting magazines? please help!
