Hello members,
Newbie from Michigan here with some questions. I am wanting to build a Bushy upper. I have a Mega Arms upper/lower billet from a previous 5.56 build. Has anyone built a 450 upper with a MEGA Billet Side Charge Upper? I am wanting to purchase a Mega side charge billet upper (https://www.rainierarms.com/upper-mega- ... ing-upper/) as I know it will mate up with my existing Mega lower. It looks like the port would be large enough from a side charge upper, saving me from modifying the ejection port. I also have other questions, like barrel length (was thinking 18"), gas port location (was thinking mid length), adjustable gas blocks, which BCG to use, and do I need a barrel with threaded end for a brake or a target crown? I will be using this for hunting southern Michigan. Max shot 200 yards. I will be reloading for this rifle as I already have reloading equipment for many other rounds. Thanks for any input.
