Best A2 Lower?

[Jakal]

For a forged lower and a no-hassel barrel nut, I'd go with Aero's M4E or M5E(AR-10) builder sets or just the get the lower. Really like the nylon adjust screw that takes up the slop between the lower and upper. I get mine just tight enough that you need a pencil, pin etc to start the take down pins. The AR was intentionally designed with slop in it. Most people say accuracy is not harmed. I don't agree with that. If you can move your upper 1/8 to the left and right, that has to cause issues downrange trying to keep a tight group.
