In the process of modifying my new H20 M4 to be 922R complaint and would love some advice. I love the M4 for what it is and would to love to keep as much of the firearm as stock as possible. But considering that changing the magazine tube requires me to change 3 parts, I'm confused as to what to change for my third item (magazine tube and follower for the first two). Seeing that my options are the trigger, trigger housing, mesa urbino stock, or forends, I was leaning more towards the forends and my reasoning is that I don't want to mess with the trigger mechanism and by luck when I purchased my M4, it was supposed to come with a pistol grip but it came with a c-stock so they sent me a free pistol grip. Having a third grip just seems wasteful at this point. My only concern with the forend is that most I have searched for seems to include m-lok slots and I was wondering if it would affect the ARGO system but allowing more dirt/dust etc. due to the opening. If that is not the case, I would love some recommendations on what seems to be a good forend. Also, I am not against changing the trigger/housing, just haven't found a good enough reason for that yet. Thank you all in advance!
