Hey so I was wondering if the lucky or the orange bolt is a good bolt to get for my PM7? Also I was wondering if the Hybrid bolt back will work on the PM7? I saw a pick of the PM6 and PM7 bolt and they are the same. So I figured it would work on the PM7. Also, if I were to get the Hybrid bolt guide, I know there is a metal tube that fills in the space on the top hat, could I use the Lucky rings with the Hybrid back (Not using the Hybrid Top Hat Ring/sleeve) ? Lastly, can the orangee bolt work with the Hybrid back? Thanks!
