I've been trying to find this information for a few days now but I've failed to find what I need, all i've been able to find are specs for the lowers only. Essentially, I'm looking for three specifics but a good set of blueprints would be best.
The three specifics are the size of the extraction hole dimensions on upper, the internal measurements of the magazine, and the bolt face size. I'm just basically wondering if the ar-10 would be able to fit a .777 bullet in its magazine single stack and if a 12 gauge upper for the ar-10 is feasible.
