I went with a MEGA upper and lower.
While only a few companies supply raw forgings, there are dozens of shops doing the final machining. Most forged 7075 units are very close in finial fit and finish. There are differences such as the mag well opening and ambi controls. Then there are the numerous billet lowers with even more custom options.
Your Mega has the Mega trade mark "Gator grip" on the front of the mag well.
