| I am building a dedicated 9MM lower and contemplating on which is the best option for the lower receiver. I have it narrowed down to 3 options. 1) Colt factory 2 pc mag block installed by M60Joe with roll pins. 2) Hahn Precision dedicated mag block or 3) Spikes mag block. I will be using a Colt upper with ramped bolt and Colt/Metalform mags. My host is a StagArms lower. What are your thoughts/experiences on this? I want the most reliable set up possible and BHO is important. |
