Hey everyone. I had a question. I was curious if someone could help me with my lower receiver build I have going. I have a friend who is helping me build our lower receivers and both of us are Military however, he is the expert at SolidWorks and is deployed. I needed 2 changes on the receiver but I have no clue how to do so lol. Any help would be much appreciated if possible. If not, I understand. Basically we just want the magwell not angled like it is and more flat like the HK416s lower magwell. I can provide more details if needed. I didn't figure I would go into to much detail in case this wasn't possible LOL. Thank you in advance.
