I'm looking to start my Umbrella Corp build. 556 pistol and was wondering what's the shortest length for reliability and accuracy. I'd like to go 7.5 but don't really want a flamethrower. Thanks for any advice.
Hey fellas, I just ordered the M5 receivers from Aero and need help on barrel length and twist. I'm thinking 18 inch mid or rifle. It would be used for deer hunting. Maybe out to 3-400 yards. What impact does bullet weight have on distance?
